\n *\n * This static operator is useful for creating a simple Observable that only\n * emits the complete notification. It can be used for composing with other\n * Observables, such as in a {@link mergeMap}.\n *\n * @example ![](\"./img/findIndex.png\")
\n *\n * `findIndex` searches for the first item in the source Observable that matches\n * the specified condition embodied by the `predicate`, and returns the\n * (zero-based) index of the first occurrence in the source. Unlike\n * {@link first}, the `predicate` is required in `findIndex`, and does not emit\n * an error if a valid value is not found.\n *\n * @example ![](\"./img/defer.png\")
\n *\n * `defer` allows you to create the Observable only when the Observer\n * subscribes, and create a fresh Observable for each Observer. It waits until\n * an Observer subscribes to it, and then it generates an Observable,\n * typically with an Observable factory function. It does this afresh for each\n * subscriber, so although each subscriber may think it is subscribing to the\n * same Observable, in fact each subscriber gets its own individual\n * Observable.\n *\n * @example ![](\"./img/defaultIfEmpty.png\"){kind=spacer}
\n *\n * `defaultIfEmpty` emits the values emitted by the source Observable or a\n * specified default value if the source Observable is empty (completes without\n * having emitted any `next` value).\n *\n * @example ![](\"./img/share.png\")
\n *\n * @return {Observable![](\"./img/elementAt.png\")
\n *\n * `elementAt` returns an Observable that emits the item at the specified\n * `index` in the source Observable, or a default value if that `index` is out\n * of range and the `default` argument is provided. If the `default` argument is\n * not given and the `index` is out of range, the output Observable will emit an\n * `ArgumentOutOfRangeError` error.\n *\n * @example ![](\"./img/reduce.png\")
\n *\n * Like\n * [Array.prototype.reduce()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce),\n * `reduce` applies an `accumulator` function against an accumulation and each\n * value of the source Observable (from the past) to reduce it to a single\n * value, emitted on the output Observable. Note that `reduce` will only emit\n * one value, only when the source Observable completes. It is equivalent to\n * applying operator {@link scan} followed by operator {@link last}.\n *\n * Returns an Observable that applies a specified `accumulator` function to each\n * item emitted by the source Observable. If a `seed` value is specified, then\n * that value will be used as the initial value for the accumulator. If no seed\n * value is specified, the first item of the source is used as the seed.\n *\n * @example ![](\"./img/fromEvent.png\")
\n *\n * `fromEvent` accepts as a first argument event target, which is an object with methods\n * for registering event handler functions. As a second argument it takes string that indicates\n * type of event we want to listen for. `fromEvent` supports selected types of event targets,\n * which are described in detail below. If your event target does not match any of the ones listed,\n * you should use {@link fromEventPattern}, which can be used on arbitrary APIs.\n * When it comes to APIs supported by `fromEvent`, their methods for adding and removing event\n * handler functions have different names, but they all accept a string describing event type\n * and function itself, which will be called whenever said event happens.\n *\n * Every time resulting Observable is subscribed, event handler function will be registered\n * to event target on given event type. When that event fires, value\n * passed as a first argument to registered function will be emitted by output Observable.\n * When Observable is unsubscribed, function will be unregistered from event target.\n *\n * Note that if event target calls registered function with more than one argument, second\n * and following arguments will not appear in resulting stream. In order to get access to them,\n * you can pass to `fromEvent` optional project function, which will be called with all arguments\n * passed to event handler. Output Observable will then emit value returned by project function,\n * instead of the usual value.\n *\n * Remember that event targets listed below are checked via duck typing. It means that\n * no matter what kind of object you have and no matter what environment you work in,\n * you can safely use `fromEvent` on that object if it exposes described methods (provided\n * of course they behave as was described above). So for example if Node.js library exposes\n * event target which has the same method names as DOM EventTarget, `fromEvent` is still\n * a good choice.\n *\n * If the API you use is more callback then event handler oriented (subscribed\n * callback function fires only once and thus there is no need to manually\n * unregister it), you should use {@link bindCallback} or {@link bindNodeCallback}\n * instead.\n *\n * `fromEvent` supports following types of event targets:\n *\n * **DOM EventTarget**\n *\n * This is an object with `addEventListener` and `removeEventListener` methods.\n *\n * In the browser, `addEventListener` accepts - apart from event type string and event\n * handler function arguments - optional third parameter, which is either an object or boolean,\n * both used for additional configuration how and when passed function will be called. When\n * `fromEvent` is used with event target of that type, you can provide this values\n * as third parameter as well.\n *\n * **Node.js EventEmitter**\n *\n * An object with `addListener` and `removeListener` methods.\n *\n * **JQuery-style event target**\n *\n * An object with `on` and `off` methods\n *\n * **DOM NodeList**\n *\n * List of DOM Nodes, returned for example by `document.querySelectorAll` or `Node.childNodes`.\n *\n * Although this collection is not event target in itself, `fromEvent` will iterate over all Nodes\n * it contains and install event handler function in every of them. When returned Observable\n * is unsubscribed, function will be removed from all Nodes.\n *\n * **DOM HtmlCollection**\n *\n * Just as in case of NodeList it is a collection of DOM nodes. Here as well event handler function is\n * installed and removed in each of elements.\n *\n *\n * @example ![](\"./img/switchMapTo.png\")
\n *\n * Maps each source value to the given Observable `innerObservable` regardless\n * of the source value, and then flattens those resulting Observables into one\n * single Observable, which is the output Observable. The output Observables\n * emits values only from the most recently emitted instance of\n * `innerObservable`.\n *\n * @example ![](\"./img/auditTime.png\")
\n *\n * `auditTime` is similar to `throttleTime`, but emits the last value from the\n * silenced time window, instead of the first value. `auditTime` emits the most\n * recent value from the source Observable on the output Observable as soon as\n * its internal timer becomes disabled, and ignores source values while the\n * timer is enabled. Initially, the timer is disabled. As soon as the first\n * source value arrives, the timer is enabled. After `duration` milliseconds (or\n * the time unit determined internally by the optional `scheduler`) has passed,\n * the timer is disabled, then the most recent source value is emitted on the\n * output Observable, and this process repeats for the next source value.\n * Optionally takes a {@link IScheduler} for managing timers.\n *\n * @example \\n

Then, each output value is given to the\n * `project` function which returns an inner Observable to be merged on the\n * output Observable.

\n *\n * Returns an Observable that emits items based on applying a function that you\n * supply to each item emitted by the source Observable, where that function\n * returns an (so-called \"inner\") Observable.

\n *\n * `delayWhen` time shifts each emitted value from the source Observable by a\n * time span determined by another Observable. When the source emits a value,\n * the `delayDurationSelector` function is called with the source value as\n * argument, and should return an Observable, called the \"duration\" Observable.\n * The source value is emitted on the output Observable only when the duration\n * Observable emits a value or completes.\n *\n * Optionally, `delayWhen` takes a second argument, `subscriptionDelay`, which\n * is an Observable. When `subscriptionDelay` emits its first value or\n * completes, the source Observable is subscribed to and starts behaving like\n * described in the previous paragraph. If `subscriptionDelay` is not provided,\n * `delayWhen` will subscribe to the source Observable as soon as the output\n * Observable is subscribed.\n *\n * @example \n *\n * `merge` subscribes to each given input Observable (as arguments), and simply\n * forwards (without doing any transformation) all the values from all the input\n * Observables to the output Observable. The output Observable only completes\n * once all input Observables have completed. Any error delivered by an input\n * Observable will be immediately emitted on the output Observable.\n *\n * @example ![](\"./img/bufferWhen.png\")
\n *\n * Opens a buffer immediately, then closes the buffer when the observable\n * returned by calling `closingSelector` function emits a value. When it closes\n * the buffer, it immediately opens a new buffer and repeats the process.\n *\n * @example ![](\"./img/takeWhile.png\")
\n *\n * `takeWhile` subscribes and begins mirroring the source Observable. Each value\n * emitted on the source is given to the `predicate` function which returns a\n * boolean, representing a condition to be satisfied by the source values. The\n * output Observable emits the source values until such time as the `predicate`\n * returns false, at which point `takeWhile` stops mirroring the source\n * Observable and completes the output Observable.\n *\n * @example \n *\n * Returns an Observable that emits items based on applying a function that you\n * supply to each item emitted by the source Observable, where that function\n * returns an (so-called \"inner\") Observable.

However, `exhaustMap` ignores every new projected\n * Observable if the previous projected Observable has not yet completed. Once\n * that one completes, it will accept and flatten the next projected Observable\n * and repeat this process.\n *\n * @example \n *\n * `defaultIfEmpty` emits the values emitted by the source Observable or a\n * specified default value if the source Observable is empty (completes without\n * having emitted any `next` value).\n *\n * @example ![](\"./img/buffer.png\")
\n *\n * Buffers the incoming Observable values until the given `closingNotifier`\n * Observable emits a value, at which point it emits the buffer on the output\n * Observable and starts a new buffer internally, awaiting the next time\n * `closingNotifier` emits.\n *\n * @example ![](\"./img/count.png\")
\n *\n * `count` transforms an Observable that emits values into an Observable that\n * emits a single value that represents the number of values emitted by the\n * source Observable. If the source Observable terminates with an error, `count`\n * will pass this error notification along without emitting a value first. If\n * the source Observable does not terminate at all, `count` will neither emit\n * a value nor terminate. This operator takes an optional `predicate` function\n * as argument, in which case the output emission will represent the number of\n * source values that matched `true` with the `predicate`.\n *\n * @example \\n \\n \\n \\n \\n \\n \\n \\n \\n \\n

If one observable never\n * completes or emits after the other complets, the returned observable will never complete.\n *\n * @example ![](\"./img/combineLatest.png\")
\n *\n * `combineLatest` combines the values from this Observable with values from\n * Observables passed as arguments. This is done by subscribing to each\n * Observable, in order, and collecting an array of each of the most recent\n * values any time any of the input Observables emits, then either taking that\n * array and passing it as arguments to an optional `project` function and\n * emitting the return value of that, or just emitting the array of recent\n * values directly if there is no `project` function.\n *\n * @example ![](\"./img/mergeMap.png\")
\n *\n * Returns an Observable that emits items based on applying a function that you\n * supply to each item emitted by the source Observable, where that function\n * returns an Observable, and then merging those resulting Observables and\n * emitting the results of this merger.\n *\n * @example ![](\"./img/onErrorResumeNext.png\")
\n *\n * `onErrorResumeNext` is an operator that accepts a series of Observables, provided either directly as\n * arguments or as an array. If no single Observable is provided, returned Observable will simply behave the same\n * as the source.\n *\n * `onErrorResumeNext` returns an Observable that starts by subscribing and re-emitting values from the source Observable.\n * When its stream of values ends - no matter if Observable completed or emitted an error - `onErrorResumeNext`\n * will subscribe to the first Observable that was passed as an argument to the method. It will start re-emitting\n * its values as well and - again - when that stream ends, `onErrorResumeNext` will proceed to subscribing yet another\n * Observable in provided series, no matter if previous Observable completed or ended with an error. This will\n * be happening until there is no more Observables left in the series, at which point returned Observable will\n * complete - even if the last subscribed stream ended with an error.\n *\n * `onErrorResumeNext` can be therefore thought of as version of {@link concat} operator, which is more permissive\n * when it comes to the errors emitted by its input Observables. While `concat` subscribes to the next Observable\n * in series only if previous one successfully completed, `onErrorResumeNext` subscribes even if it ended with\n * an error.\n *\n * Note that you do not get any access to errors emitted by the Observables. In particular do not\n * expect these errors to appear in error callback passed to {@link subscribe}. If you want to take\n * specific actions based on what error was emitted by an Observable, you should try out {@link catch} instead.\n *\n *\n * @example \n *\n * Buffers the incoming Observable values until the given `closingNotifier`\n * Observable emits a value, at which point it emits the buffer on the output\n * Observable and starts a new buffer internally, awaiting the next time\n * `closingNotifier` emits.\n *\n * @example \n *\n * @param {function(notifications: Observable): Observable} notifier - Receives an Observable of notifications with\n * which a user can `complete` or `error`, aborting the repetition.\n * @return {Observable} The source Observable modified with repeat logic.\n * @method repeatWhen\n * @owner Observable\n */\nfunction repeatWhen(notifier) {\n return function (source) { return source.lift(new RepeatWhenOperator(notifier)); };\n}\nexports.repeatWhen = repeatWhen;\nvar RepeatWhenOperator = (function () {\n function RepeatWhenOperator(notifier) {\n this.notifier = notifier;\n }\n RepeatWhenOperator.prototype.call = function (subscriber, source) {\n return source.subscribe(new RepeatWhenSubscriber(subscriber, this.notifier, source));\n };\n return RepeatWhenOperator;\n}());\n/**\n * We need this JSDoc comment for affecting ESDoc.\n * @ignore\n * @extends {Ignored}\n */\nvar RepeatWhenSubscriber = (function (_super) {\n __extends(RepeatWhenSubscriber, _super);\n function RepeatWhenSubscriber(destination, notifier, source) {\n _super.call(this, destination);\n this.notifier = notifier;\n this.source = source;\n this.sourceIsBeingSubscribedTo = true;\n }\n RepeatWhenSubscriber.prototype.notifyNext = function (outerValue, innerValue, outerIndex, innerIndex, innerSub) {\n this.sourceIsBeingSubscribedTo = true;\n this.source.subscribe(this);\n };\n RepeatWhenSubscriber.prototype.notifyComplete = function (innerSub) {\n if (this.sourceIsBeingSubscribedTo === false) {\n return _super.prototype.complete.call(this);\n }\n };\n RepeatWhenSubscriber.prototype.complete = function () {\n this.sourceIsBeingSubscribedTo = false;\n if (!this.isStopped) {\n if (!this.retries) {\n this.subscribeToRetries();\n }\n if (!this.retriesSubscription || this.retriesSubscription.closed) {\n return _super.prototype.complete.call(this);\n }\n this._unsubscribeAndRecycle();\n this.notifications.next();\n }\n };\n /** @deprecated internal use only */ RepeatWhenSubscriber.prototype._unsubscribe = function () {\n var _a = this, notifications = _a.notifications, retriesSubscription = _a.retriesSubscription;\n if (notifications) {\n notifications.unsubscribe();\n this.notifications = null;\n }\n if (retriesSubscription) {\n retriesSubscription.unsubscribe();\n this.retriesSubscription = null;\n }\n this.retries = null;\n };\n /** @deprecated internal use only */ RepeatWhenSubscriber.prototype._unsubscribeAndRecycle = function () {\n var _a = this, notifications = _a.notifications, retries = _a.retries, retriesSubscription = _a.retriesSubscription;\n this.notifications = null;\n this.retries = null;\n this.retriesSubscription = null;\n _super.prototype._unsubscribeAndRecycle.call(this);\n this.notifications = notifications;\n this.retries = retries;\n this.retriesSubscription = retriesSubscription;\n return this;\n };\n RepeatWhenSubscriber.prototype.subscribeToRetries = function () {\n this.notifications = new Subject_1.Subject();\n var retries = tryCatch_1.tryCatch(this.notifier)(this.notifications);\n if (retries === errorObject_1.errorObject) {\n return _super.prototype.complete.call(this);\n }\n this.retries = retries;\n this.retriesSubscription = subscribeToResult_1.subscribeToResult(this, retries);\n };\n return RepeatWhenSubscriber;\n}(OuterSubscriber_1.OuterSubscriber));\n//# sourceMappingURL=repeatWhen.js.map\n\n\n// WEBPACK FOOTER //\n// ./node_modules/rxjs/operators/repeatWhen.js.pre-build-optimizer.js","\"use strict\";\nvar switchMap_1 = require('./switchMap');\nvar identity_1 = require('../util/identity');\nfunction switchAll() {\n return switchMap_1.switchMap(identity_1.identity);\n}\nexports.switchAll = switchAll;\n//# sourceMappingURL=switchAll.js.map\n\n\n//////////////////\n// WEBPACK FOOTER\n// ./node_modules/rxjs/operators/switchAll.js\n// module id = Am8Y\n// module chunks = 0","//! moment.js locale configuration\n//! locale : Portuguese (Brazil) [pt-br]\n//! author : Caio Ribeiro Pereira : https://github.com/caio-ribeiro-pereira\n\n;(function (global, factory) {\n typeof exports === 'object' && typeof module !== 'undefined'\n && typeof require === 'function' ?
