Even though WeakMapModule is not global, the linter thinks it - * is, which is why it is in the overrides list below. - * - *

NOTE: Before using this WeakMap emulation in a non-SES - * environment, see the note below about hiddenRecord. - * - * @author Mark S. Miller - * @requires crypto, ArrayBuffer, Uint8Array, navigator, console - * @overrides WeakMap, ses, Proxy - * @overrides WeakMapModule - */ +},{"./bn-sign":374,"./num-to-bn":378}],380:[function(require,module,exports){ +'use strict' -/** - * This {@code WeakMap} emulation is observably equivalent to the - * ES-Harmony WeakMap, but with leakier garbage collection properties. - * - *

As with true WeakMaps, in this emulation, a key does not - * retain maps indexed by that key and (crucially) a map does not - * retain the keys it indexes. A map by itself also does not retain - * the values associated with that map. - * - *

However, the values associated with a key in some map are - * retained so long as that key is retained and those associations are - * not overridden. For example, when used to support membranes, all - * values exported from a given membrane will live for the lifetime - * they would have had in the absence of an interposed membrane. Even - * when the membrane is revoked, all objects that would have been - * reachable in the absence of revocation will still be reachable, as - * far as the GC can tell, even though they will no longer be relevant - * to ongoing computation. - * - *

The API implemented here is approximately the API as implemented - * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman, - * rather than the offially approved proposal page. TODO(erights): - * upgrade the ecmascript WeakMap proposal page to explain this API - * change and present to EcmaScript committee for their approval. - * - *

The first difference between the emulation here and that in - * FF6.0a1 is the presence of non enumerable {@code get___, has___, - * set___, and delete___} methods on WeakMap instances to represent - * what would be the hidden internal properties of a primitive - * implementation. Whereas the FF6.0a1 WeakMap.prototype methods - * require their {@code this} to be a genuine WeakMap instance (i.e., - * an object of {@code [[Class]]} "WeakMap}), since there is nothing - * unforgeable about the pseudo-internal method names used here, - * nothing prevents these emulated prototype methods from being - * applied to non-WeakMaps with pseudo-internal methods of the same - * names. - * - *

Another difference is that our emulated {@code - * WeakMap.prototype} is not itself a WeakMap. A problem with the - * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap - * providing ambient mutability and an ambient communications - * channel. Thus, if a WeakMap is already present and has this - * problem, repairES5.js wraps it in a safe wrappper in order to - * prevent access to this channel.

To treat objects as identity-keys with reasonable efficiency - * on ES5 by itself (i.e., without any object-keyed collections), we - * need to add a hidden property to such key objects when we - * can. This raises several issues: - *

    - *
  • Arranging to add this property to objects before we lose the - * chance, and - *
  • Hiding the existence of this new property from most - * JavaScript code. - *
  • Preventing certification theft, where one object is - * created falsely claiming to be the key of an association - * actually keyed by another object. - *
  • Preventing value theft, where untrusted code with - * access to a key object but not a weak map nevertheless - * obtains access to the value associated with that key in that - * weak map. - *
- * We do so by - *
    - *
  • Making the name of the hidden property unguessable, so "[]" - * indexing, which we cannot intercept, cannot be used to access - * a property without knowing the name. - *
  • Making the hidden property non-enumerable, so we need not - * worry about for-in loops or {@code Object.keys}, - *
  • monkey patching those reflective methods that would - * prevent extensions, to add this hidden property first, - *
  • monkey patching those methods that would reveal this - * hidden property. - *
- * Unfortunately, because of same-origin iframes, we cannot reliably - * add this hidden property before an object becomes - * non-extensible.

Assumes that an ES5 platform where, if {@code WeakMap} is + * already present, then it conforms to the anticipated ES6 + * specification. To run this file on an ES5 or almost ES5 + * implementation where the {@code WeakMap} specification does not + * quite conform, run repairES5.js first. + * + *

Even though WeakMapModule is not global, the linter thinks it + * is, which is why it is in the overrides list below. + * + *

NOTE: Before using this WeakMap emulation in a non-SES + * environment, see the note below about hiddenRecord. + * + * @author Mark S. Miller + * @requires crypto, ArrayBuffer, Uint8Array, navigator, console + * @overrides WeakMap, ses, Proxy + * @overrides WeakMapModule + */ + +/** + * This {@code WeakMap} emulation is observably equivalent to the + * ES-Harmony WeakMap, but with leakier garbage collection properties. + * + *

As with true WeakMaps, in this emulation, a key does not + * retain maps indexed by that key and (crucially) a map does not + * retain the keys it indexes. A map by itself also does not retain + * the values associated with that map. + * + *

However, the values associated with a key in some map are + * retained so long as that key is retained and those associations are + * not overridden. For example, when used to support membranes, all + * values exported from a given membrane will live for the lifetime + * they would have had in the absence of an interposed membrane. Even + * when the membrane is revoked, all objects that would have been + * reachable in the absence of revocation will still be reachable, as + * far as the GC can tell, even though they will no longer be relevant + * to ongoing computation. + * + *

The API implemented here is approximately the API as implemented + * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman, + * rather than the offially approved proposal page. TODO(erights): + * upgrade the ecmascript WeakMap proposal page to explain this API + * change and present to EcmaScript committee for their approval. + * + *

The first difference between the emulation here and that in + * FF6.0a1 is the presence of non enumerable {@code get___, has___, + * set___, and delete___} methods on WeakMap instances to represent + * what would be the hidden internal properties of a primitive + * implementation. Whereas the FF6.0a1 WeakMap.prototype methods + * require their {@code this} to be a genuine WeakMap instance (i.e., + * an object of {@code [[Class]]} "WeakMap}), since there is nothing + * unforgeable about the pseudo-internal method names used here, + * nothing prevents these emulated prototype methods from being + * applied to non-WeakMaps with pseudo-internal methods of the same + * names. + * + *

Another difference is that our emulated {@code + * WeakMap.prototype} is not itself a WeakMap. A problem with the + * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap + * providing ambient mutability and an ambient communications + * channel. Thus, if a WeakMap is already present and has this + * problem, repairES5.js wraps it in a safe wrappper in order to + * prevent access to this channel.

To treat objects as identity-keys with reasonable efficiency + * on ES5 by itself (i.e., without any object-keyed collections), we + * need to add a hidden property to such key objects when we + * can. This raises several issues: + *

    + *
  • Arranging to add this property to objects before we lose the + * chance, and + *
  • Hiding the existence of this new property from most + * JavaScript code. + *
  • Preventing certification theft, where one object is + * created falsely claiming to be the key of an association + * actually keyed by another object. + *
  • Preventing value theft, where untrusted code with + * access to a key object but not a weak map nevertheless + * obtains access to the value associated with that key in that + * weak map. + *
+ * We do so by + *
    + *
  • Making the name of the hidden property unguessable, so "[]" + * indexing, which we cannot intercept, cannot be used to access + * a property without knowing the name. + *
  • Making the hidden property non-enumerable, so we need not + * worry about for-in loops or {@code Object.keys}, + *

Even though WeakMapModule is not global, the linter thinks it - * is, which is why it is in the overrides list below. - * - *

NOTE: Before using this WeakMap emulation in a non-SES - * environment, see the note below about hiddenRecord. - * - * @author Mark S. Miller - * @requires crypto, ArrayBuffer, Uint8Array, navigator, console - * @overrides WeakMap, ses, Proxy - * @overrides WeakMapModule - */ +},{"./bn-sign":374,"./num-to-bn":378}],380:[function(require,module,exports){ +'use strict' -/** - * This {@code WeakMap} emulation is observably equivalent to the - * ES-Harmony WeakMap, but with leakier garbage collection properties. - * - *

As with true WeakMaps, in this emulation, a key does not - * retain maps indexed by that key and (crucially) a map does not - * retain the keys it indexes. A map by itself also does not retain - * the values associated with that map. - * - *

However, the values associated with a key in some map are - * retained so long as that key is retained and those associations are - * not overridden. For example, when used to support membranes, all - * values exported from a given membrane will live for the lifetime - * they would have had in the absence of an interposed membrane. Even - * when the membrane is revoked, all objects that would have been - * reachable in the absence of revocation will still be reachable, as - * far as the GC can tell, even though they will no longer be relevant - * to ongoing computation. - * - *

The API implemented here is approximately the API as implemented - * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman, - * rather than the offially approved proposal page. TODO(erights): - * upgrade the ecmascript WeakMap proposal page to explain this API - * change and present to EcmaScript committee for their approval. - * - *

The first difference between the emulation here and that in - * FF6.0a1 is the presence of non enumerable {@code get___, has___, - * set___, and delete___} methods on WeakMap instances to represent - * what would be the hidden internal properties of a primitive - * implementation. Whereas the FF6.0a1 WeakMap.prototype methods - * require their {@code this} to be a genuine WeakMap instance (i.e., - * an object of {@code [[Class]]} "WeakMap}), since there is nothing - * unforgeable about the pseudo-internal method names used here, - * nothing prevents these emulated prototype methods from being - * applied to non-WeakMaps with pseudo-internal methods of the same - * names. - * - *

Another difference is that our emulated {@code - * WeakMap.prototype} is not itself a WeakMap. A problem with the - * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap - * providing ambient mutability and an ambient communications - * channel. Thus, if a WeakMap is already present and has this - * problem, repairES5.js wraps it in a safe wrappper in order to - * prevent access to this channel.

To treat objects as identity-keys with reasonable efficiency - * on ES5 by itself (i.e., without any object-keyed collections), we - * need to add a hidden property to such key objects when we - * can. This raises several issues: - *

    - *
  • Arranging to add this property to objects before we lose the - * chance, and - *
  • Hiding the existence of this new property from most - * JavaScript code. - *
  • Preventing certification theft, where one object is - * created falsely claiming to be the key of an association - * actually keyed by another object. - *
  • Preventing value theft, where untrusted code with - * access to a key object but not a weak map nevertheless - * obtains access to the value associated with that key in that - * weak map. - *
- * We do so by - *
    - *
  • Making the name of the hidden property unguessable, so "[]" - * indexing, which we cannot intercept, cannot be used to access - * a property without knowing the name. - *
  • Making the hidden property non-enumerable, so we need not - * worry about for-in loops or {@code Object.keys}, - *
  • monkey patching those reflective methods that would - * prevent extensions, to add this hidden property first, - *
  • monkey patching those methods that would reveal this - * hidden property. - *
- * Unfortunately, because of same-origin iframes, we cannot reliably - * add this hidden property before an object becomes - * non-extensible.

Assumes that an ES5 platform where, if {@code WeakMap} is + * already present, then it conforms to the anticipated ES6 + * specification. To run this file on an ES5 or almost ES5 + * implementation where the {@code WeakMap} specification does not + * quite conform, run repairES5.js first. + * + *

Even though WeakMapModule is not global, the linter thinks it + * is, which is why it is in the overrides list below. + * + *

NOTE: Before using this WeakMap emulation in a non-SES + * environment, see the note below about hiddenRecord. + * + * @author Mark S. Miller + * @requires crypto, ArrayBuffer, Uint8Array, navigator, console + * @overrides WeakMap, ses, Proxy + * @overrides WeakMapModule + */ + +/** + * This {@code WeakMap} emulation is observably equivalent to the + * ES-Harmony WeakMap, but with leakier garbage collection properties. + * + *

As with true WeakMaps, in this emulation, a key does not + * retain maps indexed by that key and (crucially) a map does not + * retain the keys it indexes. A map by itself also does not retain + * the values associated with that map. + * + *

However, the values associated with a key in some map are + * retained so long as that key is retained and those associations are + * not overridden. For example, when used to support membranes, all + * values exported from a given membrane will live for the lifetime + * they would have had in the absence of an interposed membrane. Even + * when the membrane is revoked, all objects that would have been + * reachable in the absence of revocation will still be reachable, as + * far as the GC can tell, even though they will no longer be relevant + * to ongoing computation. + * + *

The API implemented here is approximately the API as implemented + * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman, + * rather than the offially approved proposal page. TODO(erights): + * upgrade the ecmascript WeakMap proposal page to explain this API + * change and present to EcmaScript committee for their approval. + * + *

The first difference between the emulation here and that in + * FF6.0a1 is the presence of non enumerable {@code get___, has___, + * set___, and delete___} methods on WeakMap instances to represent + * what would be the hidden internal properties of a primitive + * implementation. Whereas the FF6.0a1 WeakMap.prototype methods + * require their {@code this} to be a genuine WeakMap instance (i.e., + * an object of {@code [[Class]]} "WeakMap}), since there is nothing + * unforgeable about the pseudo-internal method names used here, + * nothing prevents these emulated prototype methods from being + * applied to non-WeakMaps with pseudo-internal methods of the same + * names. + * + *

Another difference is that our emulated {@code + * WeakMap.prototype} is not itself a WeakMap. A problem with the + * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap + * providing ambient mutability and an ambient communications + * channel. Thus, if a WeakMap is already present and has this + * problem, repairES5.js wraps it in a safe wrappper in order to + * prevent access to this channel.

To treat objects as identity-keys with reasonable efficiency + * on ES5 by itself (i.e., without any object-keyed collections), we + * need to add a hidden property to such key objects when we + * can. This raises several issues: + *

    + *
  • Arranging to add this property to objects before we lose the + * chance, and + *
  • Hiding the existence of this new property from most + * JavaScript code. + *
  • Preventing certification theft, where one object is + * created falsely claiming to be the key of an association + * actually keyed by another object. + *
  • Preventing value theft, where untrusted code with + * access to a key object but not a weak map nevertheless + * obtains access to the value associated with that key in that + * weak map. + *
+ * We do so by + *
    + *
  • Making the name of the hidden property unguessable, so "[]" + * indexing, which we cannot intercept, cannot be used to access + * a property without knowing the name. + *
  • Making the hidden property non-enumerable, so we need not + * worry about for-in loops or {@code Object.keys}, + *

The - primary way of interacting with a promise is through its `then` method, which - registers callbacks to receive either a promise's eventual value or the reason - why the promise cannot be fulfilled. - - Terminology - ----------- - - - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - - `thenable` is an object or function that defines a `then` method. - - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - - `exception` is a value that is thrown using the throw statement. - - `reason` is a value that indicates why a promise was rejected. - - `settled` the final resting state of a promise, fulfilled or rejected. - - A promise can be in one of three states: pending, fulfilled, or rejected. - - Promises that are fulfilled have a fulfillment value and are in the fulfilled - state. Promises that are rejected have a rejection reason and are in the - rejected state. A fulfillment value is never a thenable. - - Promises can also be said to *resolve* a value. If this value is also a - promise, then the original promise's settled state will match the value's - settled state. So a promise that *resolves* a promise that rejects will - itself reject, and a promise that *resolves* a promise that fulfills will - itself fulfill. - - - Basic Usage: - ------------ - - ```js - var promise = new Promise(function(resolve, reject) { - // on success - resolve(value); - - // on failure - reject(reason); - }); - - promise.then(function(value) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Advanced Usage: - --------------- - - Promises shine when abstracting away asynchronous interactions such as - `XMLHttpRequest`s. - - ```js - function getJSON(url) { - return new Promise(function(resolve, reject){ - var xhr = new XMLHttpRequest(); - - xhr.open('GET', url); - xhr.onreadystatechange = handler; - xhr.responseType = 'json'; - xhr.setRequestHeader('Accept', 'application/json'); - xhr.send(); - - function handler() { - if (this.readyState === this.DONE) { - if (this.status === 200) { - resolve(this.response); - } else { - reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); - } - } - }; - }); - } - - getJSON('/posts.json').then(function(json) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Unlike callbacks, promises are great composable primitives. - - ```js - Promise.all([ - getJSON('/posts'), - getJSON('/comments') - ]).then(function(values){ - values[0] // => postsJSON - values[1] // => commentsJSON - - return values; - }); - ``` - - @class Promise - @param {function} resolver - Useful for tooling. - @constructor - */ - function lib$es6$promise$promise$$Promise(resolver) { - this[lib$es6$promise$$internal$$PROMISE_ID] = lib$es6$promise$$internal$$nextId(); - this._result = this._state = undefined; - this._subscribers = []; - - if (lib$es6$promise$$internal$$noop !== resolver) { - typeof resolver !== 'function' && lib$es6$promise$promise$$needsResolver(); - this instanceof lib$es6$promise$promise$$Promise ? lib$es6$promise$$internal$$initializePromise(this, resolver) : lib$es6$promise$promise$$needsNew(); - } + }; + var d3_geo_streamGeometryType = { + Sphere: function(object, listener) { + listener.sphere(); + }, + Point: function(object, listener) { + object = object.coordinates; + listener.point(object[0], object[1], object[2]); + }, + MultiPoint: function(object, listener) { + var coordinates = object.coordinates, i = -1, n = coordinates.length; + while (++i < n) object = coordinates[i], listener.point(object[0], object[1], object[2]); + }, + LineString: function(object, listener) { + d3_geo_streamLine(object.coordinates, listener, 0); + }, + MultiLineString: function(object, listener) { + var coordinates = object.coordinates, i = -1, n = coordinates.length; + while (++i < n) d3_geo_streamLine(coordinates[i], listener, 0); + }, + Polygon: function(object, listener) { + d3_geo_streamPolygon(object.coordinates, listener); + }, + MultiPolygon: function(object, listener) { + var coordinates = object.coordinates, i = -1, n = coordinates.length; + while (++i < n) d3_geo_streamPolygon(coordinates[i], listener); + }, + GeometryCollection: function(object, listener) { + var geometries = object.geometries, i = -1, n = geometries.length; + while (++i < n) d3_geo_streamGeometry(geometries[i], listener); } - - lib$es6$promise$promise$$Promise.all = lib$es6$promise$promise$all$$default; - lib$es6$promise$promise$$Promise.race = lib$es6$promise$promise$race$$default; - lib$es6$promise$promise$$Promise.resolve = lib$es6$promise$promise$resolve$$default; - lib$es6$promise$promise$$Promise.reject = lib$es6$promise$promise$reject$$default; - lib$es6$promise$promise$$Promise._setScheduler = lib$es6$promise$asap$$setScheduler; - lib$es6$promise$promise$$Promise._setAsap = lib$es6$promise$asap$$setAsap; - lib$es6$promise$promise$$Promise._asap = lib$es6$promise$asap$$asap; - - lib$es6$promise$promise$$Promise.prototype = { - constructor: lib$es6$promise$promise$$Promise, - - /** - The primary way of interacting with a promise is through its `then` method, - which registers callbacks to receive either a promise's eventual value or the - reason why the promise cannot be fulfilled. - - ```js - findUser().then(function(user){ - // user is available - }, function(reason){ - // user is unavailable, and you are given the reason why - }); - ``` - - Chaining - -------- - - The return value of `then` is itself a promise.

This can be achieved by returning a promise in the - fulfillment or rejection handler. The downstream promise will then be pending - until the returned promise is settled. This is called *assimilation*. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // The user's comments are now available - }); - ``` - - If the assimliated promise rejects, then the downstream promise will also reject. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user);

Even though WeakMapModule is not global, the linter thinks it + * is, which is why it is in the overrides list below. + * + *

NOTE: Before using this WeakMap emulation in a non-SES + * environment, see the note below about hiddenRecord. + * + * @author Mark S. Miller + * @requires crypto, ArrayBuffer, Uint8Array, navigator, console + * @overrides WeakMap, ses, Proxy + * @overrides WeakMapModule + */ -Red.prototype.iadd = function iadd(a, b) { - this._verify2(a, b); +/** + * This {@code WeakMap} emulation is observably equivalent to the + * ES-Harmony WeakMap, but with leakier garbage collection properties. + * + *

As with true WeakMaps, in this emulation, a key does not + * retain maps indexed by that key and (crucially) a map does not + * retain the keys it indexes. A map by itself also does not retain + * the values associated with that map. + * + *

However, the values associated with a key in some map are + * retained so long as that key is retained and those associations are + * not overridden. For example, when used to support membranes, all + * values exported from a given membrane will live for the lifetime + * they would have had in the absence of an interposed membrane. Even + * when the membrane is revoked, all objects that would have been + * reachable in the absence of revocation will still be reachable, as + * far as the GC can tell, even though they will no longer be relevant + * to ongoing computation. + * + *

The API implemented here is approximately the API as implemented + * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman, + * rather than the offially approved proposal page. TODO(erights): + * upgrade the ecmascript WeakMap proposal page to explain this API + * change and present to EcmaScript committee for their approval. + * + *

The first difference between the emulation here and that in + * FF6.0a1 is the presence of non enumerable {@code get___, has___, + * set___, and delete___} methods on WeakMap instances to represent + * what would be the hidden internal properties of a primitive + * implementation. Whereas the FF6.0a1 WeakMap.prototype methods + * require their {@code this} to be a genuine WeakMap instance (i.e., + * an object of {@code [[Class]]} "WeakMap}), since there is nothing + * unforgeable about the pseudo-internal method names used here, + * nothing prevents these emulated prototype methods from being + * applied to non-WeakMaps with pseudo-internal methods of the same + * names. + * + *

Another difference is that our emulated {@code + * WeakMap.prototype} is not itself a WeakMap. A problem with the + * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap + * providing ambient mutability and an ambient communications + * channel. Thus, if a WeakMap is already present and has this + * problem, repairES5.js wraps it in a safe wrappper in order to + * prevent access to this channel.

Assumes that an ES5 platform where, if {@code WeakMap} is - * already present, then it conforms to the anticipated ES6 - * specification. To run this file on an ES5 or almost ES5 - * implementation where the {@code WeakMap} specification does not - * quite conform, run repairES5.js first. - * - *

Even though WeakMapModule is not global, the linter thinks it - * is, which is why it is in the overrides list below. - * - *

NOTE: Before using this WeakMap emulation in a non-SES - * environment, see the note below about hiddenRecord. - * - * @author Mark S. Miller - * @requires crypto, ArrayBuffer, Uint8Array, navigator, console - * @overrides WeakMap, ses, Proxy - * @overrides WeakMapModule - */ - -/** - * This {@code WeakMap} emulation is observably equivalent to the - * ES-Harmony WeakMap, but with leakier garbage collection properties. - * - *

As with true WeakMaps, in this emulation, a key does not - * retain maps indexed by that key and (crucially) a map does not - * retain the keys it indexes. A map by itself also does not retain - * the values associated with that map. - * - *

However, the values associated with a key in some map are - * retained so long as that key is retained and those associations are - * not overridden. For example, when used to support membranes, all - * values exported from a given membrane will live for the lifetime - * they would have had in the absence of an interposed membrane. Even - * when the membrane is revoked, all objects that would have been - * reachable in the absence of revocation will still be reachable, as - * far as the GC can tell, even though they will no longer be relevant - * to ongoing computation. - * - *

The API implemented here is approximately the API as implemented - * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman, - * rather than the offially approved proposal page. TODO(erights): - * upgrade the ecmascript WeakMap proposal page to explain this API - * change and present to EcmaScript committee for their approval. - * - *

The first difference between the emulation here and that in - * FF6.0a1 is the presence of non enumerable {@code get___, has___, - * set___, and delete___} methods on WeakMap instances to represent - * what would be the hidden internal properties of a primitive - * implementation. Whereas the FF6.0a1 WeakMap.prototype methods - * require their {@code this} to be a genuine WeakMap instance (i.e., - * an object of {@code [[Class]]} "WeakMap}), since there is nothing - * unforgeable about the pseudo-internal method names used here, - * nothing prevents these emulated prototype methods from being - * applied to non-WeakMaps with pseudo-internal methods of the same - * names. - * - *

Another difference is that our emulated {@code - * WeakMap.prototype} is not itself a WeakMap. A problem with the - * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap - * providing ambient mutability and an ambient communications - * channel. Thus, if a WeakMap is already present and has this - * problem, repairES5.js wraps it in a safe wrappper in order to - * prevent access to this channel. (See - * PATCH_MUTABLE_FROZEN_WEAKMAP_PROTO in repairES5.js). - */ - -/** - * If this is a full secureable ES5 platform and the ES-Harmony {@code WeakMap} is - * absent, install an approximate emulation. - * - *

If WeakMap is present but cannot store some objects, use our approximate - * emulation as a wrapper. - * - *

If this is almost a secureable ES5 platform, then WeakMap.js - * should be run after repairES5.js. - * - *
