Ignores source values for a duration determined by another Observable, then emits the most recent value from the source Observable, then repeats this process.
Ignores source values for a duration determined by another Observable, then emits the most recent value from the source Observable, then repeats this process.
It's like auditTime, but the silencing duration is determined by a second Observable.
audit is similar to throttle, but emits the last value from the silenced
time window, instead of the first value. audit emits the most recent value
from the source Observable on the output Observable as soon as its internal
timer becomes disabled, and ignores source values while the timer is enabled.
Initially, the timer is disabled. As soon as the first source value arrives,
the timer is enabled by calling the durationSelector function with the
source value, which returns the "duration" Observable. When the duration
Observable emits a value or completes, the timer is disabled, then the most
recent source value is emitted on the output Observable, and this process
repeats for the next source value.
A function that receives a value from the source Observable, for computing the silencing duration, returned as an Observable or a Promise.
{Observable[T]} An Observable that performs rate-limiting of emissions from the source Observable.
val result = clickStream.audit(ev => Observable.interval(1000)) result.subscribe(x => println(x))

value from the source Observable, then repeats this process.
Ignores source values for duration milliseconds, then emits the most recent
value from the source Observable, then repeats this process.
When it sees a source values, it ignores that plus the next ones for `duration` milliseconds, and then it emits the most recent value from the source.
auditTime is similar to throttleTime, but emits the last value from the
silenced time window, instead of the first value. auditTime emits the most
recent value from the source Observable on the output Observable as soon as
its internal timer becomes disabled, and ignores source values while the
timer is enabled. Initially, the timer is disabled. As soon as the first
source value arrives, the timer is enabled. After duration milliseconds (or
the time unit determined internally by the optional scheduler) has passed,
the timer is disabled, then the most recent source value is emitted on the
output Observable, and this process repeats for the next source value.
Optionally takes a Scheduler for managing timers.
Time to wait before emitting the most recent source
value, measured in milliseconds or the time unit determined internally
by the optional scheduler.

This technique, which is called "fold" or "reduce" here, is sometimes called "aggregate,"
"accumulate," "compress," or "inject" in other programming contexts. Groovy, for instance,
has an inject method that does a similar operation on lists.

Groups the items emitted by an Observable according to a specified criterion, and emits these
grouped items as (key, observable) pairs.
Note: A (key, observable) will cache the items it is to emit until such time as it
is subscribed to. For this reason, in order to avoid memory leaks, you should not simply ignore those
(key, observable) pairs that do not concern you. Instead, you can signal to them that they may
discard their buffers by applying an operator like take(0) to them.

Instruct an Observable to pass control to another Observable rather than invoking onError if it encounters an error.
Instruct an Observable to pass control to another Observable rather than invoking onError if it encounters an error.
By default, when an Observable encounters an error that prevents it from emitting the
expected item to its Observer, the Observable invokes its Observer's
onError method, and then quits without invoking any more of its Observer's
methods. The onErrorResumeNext method changes this behavior. If you pass a
function that returns an Observable (resumeFunction) to
onErrorResumeNext, if the original Observable encounters an error, instead of
invoking its Observer's onError method, it will instead relinquish control to
the Observable returned from resumeFunction, which will invoke the Observer's
onNext method if it is able to do so. In such a case, because no
Observable necessarily invokes onError, the Observer may never know that an
error happened.
You can use this to prevent errors from propagating or to supply fallback data should errors be encountered.

(resumeFunction) to an Observable's onErrorReturn method, if the
original Observable encounters an error, instead of invoking its Observer's
onError method, it will instead pass the return value of
resumeFunction to the Observer's onNext method.
You can use this to prevent errors from propagating or to supply fallback data should errors be encountered.

Retry subscription to origin Observable upto given retry count.
If Observer.onError is invoked the source Observable will be re-subscribed to as many times as defined by retryCount.
Any Observer.onNext calls received on each attempt will be emitted and concatenated together.
For example, if an Observable fails on first time but emits [1, 2] then succeeds the second time and emits [1, 2, 3, 4, 5] then the complete output would be [1, 2, 1, 2, 3, 4, 5, onCompleted].

Observable with retry logic.
Returns an Observable that emits the same values as the source observable with the exception of an
onError.
Returns an Observable that emits the same values as the source observable with the exception of an
onError. An onError notification from the source will result in the emission of a
Throwable to the Observable provided as an argument to the notificationHandler
function. If the Observable returned onCompletes or onErrors then retry will call
onCompleted or onError on the child subscription. Otherwise, this Observable will
resubscribe to the source Observable.
Example:
This retries 3 times, each time incrementing the number of seconds it waits.
receives an Observable of a Throwable with which a user can complete or error, aborting the retry
the source Observable modified with retry logic
This retries 3 times, each time incrementing the number of seconds it waits.

Call this method to subscribe an Observer for receiving items and notifications from the Observable.
Call this method to subscribe an Observer for receiving items and notifications from the Observable.
A typical implementation of subscribe does the following:
It stores a reference to the Observer in a collection object, such as a List[T] object.
It returns a reference to the subscription.Subscription interface. This enables Observers to unsubscribe, that is, to stop receiving items and notifications before the Observable stops sending them, which also invokes the Observer's Observer.complete() method.
An Observable[T] instance is responsible for accepting all subscriptions
and notifying all Observers. Unless the documentation for a particular
Observable[T] implementation indicates otherwise, Observers should make no
assumptions about the order in which multiple Observers will receive their notifications.

Emits a value from the source Observable, then ignores subsequent source values for a duration determined by another Observable, then repeats this process.
Emits a value from the source Observable, then ignores subsequent source values for a duration determined by another Observable, then repeats this process.
It's like throttleTime, but the silencing duration is determined by a second Observable.
throttle emits the source Observable values on the output Observable
when its internal timer is disabled, and ignores source values when the timer
is enabled. Initially, the timer is disabled. As soon as the first source
value arrives, it is forwarded to the output Observable, and then the timer
is enabled by calling the durationSelector function with the source value,
which returns the "duration" Observable. When the duration Observable emits a
value or completes, the timer is disabled, and this process repeats for the
next source value.

Returns an Observable that emits a single item, a list composed of all the items emitted by the source Observable.
Returns an Observable that emits a single item, a list composed of all the items emitted by the source Observable.
Normally, an Observable that returns multiple items will do so by invoking its rxscalajs.subscription.ObserverFacade's
onNext method for each such item. You can change
this behavior, instructing the Observable to compose a list of all of these items and then to
invoke the Observer's onNext function once, passing it the entire list, by
calling the Observable's toList method prior to calling its Observable.subscribe method.
Be careful not to use this operator on Observables that emit infinite or very large numbers of items, as you do not have the option to unsubscribe.

Observable produces an object. That object is used to construct an Observable to emit windows, feeding it into closings function.
Windows are emitted when the created Observable produces an object.
The rxscalajs.Observable which when it produces an object, will cause another window to be created.
The function which is used to produce an rxscalajs.Observable for every window created. When this rxscalajs.Observable produces an object, the associated window is emitted.

Returns an Observable formed from this Observable and another Observable by combining
corresponding elements in pairs.
The number of onNext invocations of the resulting Observable[(T, U)]
is the minumum of the number of onNext invocations of this and that.
the Observable to zip with

Returns an Observable that emits items that are the result of applying a specified function to pairs of values, one each from the source Observable and a specified Iterable sequence.
Returns an Observable that emits items that are the result of applying a specified function to pairs of values, one each from the source Observable and a specified Iterable sequence.
Note that the other Iterable is evaluated as items are observed from the source Observable it is
not pre-consumed. This allows you to zip infinite streams on either side.
