The Window object implements a function matchMedia that returns a response of type MediaQueryList. range. Returns an observable sequence that is the result of invoking the selector on a connectable observable sequence that shares a single subscription to the underlying sequence replaying bufferSize notifications within window. (Defined by, Overloaded. (Defined by, Overloaded. has passed without another source emission. satisfied. Returns an Observable that emits only the last item emitted by the source Observable. emits an error notification. while still sharing its values between multiple subscribers. Creates a dictionary from an observable sequence according to a specified key selector function, and an element selector function. Combines multiple Observables to create an Observable whose values are auditTime(duration: number, scheduler: Scheduler): Observable. ReplaySubject in @staltz's definition is missing a number of things including the buffer size according to relative time. We'll also see how to use the async pipe to subscribe to Observables from templates Represents all of the notifications from the source Observable as next (Defined by, Overloaded. (Defined by, Overloaded. Projects each element of an observable sequence into consecutive non-overlapping windows. Applies an accumulator function over an observable sequence. (Defined by, Overloaded. To be more in line with BehaviorSubject, it could also be a method returning the buffer: ReplaySubject.getBuffer. throw(error: any, scheduler: Scheduler): Observable. (Defined by, Overloaded. do(nextOrObserver: Observer | function, error: function, complete: function): Observable. accumulator function itself returns an Observable, then each intermediate periodic time intervals. Bypasses values in an observable sequence as long as a specified condition is true and then returns the remaining values. (Defined by, Samples the next value (blocking without buffering) from in an observable sequence. (Defined by, Overloaded. concatMapTo(innerObservable: ObservableInput, resultSelector: function(outerValue: T, innerValue: I, outerIndex: number, innerIndex: number): any): Observable. factory function of closing Observables to determine when to start a new two values. Emits a value from the source Observable only after a particular time span Any public static (Shared in Visual Basic) members of this type are thread safe. concat(input1: ObservableInput, input2: ObservableInput, scheduler: Scheduler): Observable. Returns the first element of an observable sequence that matches the predicate, or a default value if no value is found. Assembly:  System.Reactive (in System.Reactive.dll). Determines whether an observable sequence contains a specified element by using a specified System.Collections.Generic.IEqualityComparer<T>. (Defined by, Overloaded. and when source Observable completes it emits a single item: the item with the smallest value. A ReplaySubject buffers items it receives. (Defined by, Overloaded. Examples. (Defined by, Invokes an action for each element in the observable sequence, and blocks until the sequence is terminated. Creates an output Observable which concurrently emits all values from every emitted by the source Observable. the output Observable. Creates an Observable that emits events of a specific type coming from the Determines whether an observable sequence contains any elements. pass the condition. throttle(durationSelector: function(value: T): SubscribableOrPromise, config: Object): Observable. whose values are calculated from the latest values of each, only when the multicast(subjectOrSubjectFactory: Function | Subject, selector: Function): Observable. debounce(durationSelector: function(value: T): SubscribableOrPromise): Observable. subscribes to the second Observable. Returns an observable sequence that contains only distinct elements according to the keySelector. Projects each element of an observable sequence into a new form by incorporating the element’s index with the specified source and selector. (Defined by, Overloaded. The ReplaySubject type exposes the following members. (Defined by, Overloaded. Records the timestamp for each value in an observable sequence with the specified source. an emission from openings and ending when the output of closingSelector (Defined by, Invokes a specified action after source observable sequence terminates normally or by an exception. Emits only the first value emitted by the source Observable that meets some Buffers the source Observable values for a specific time period. merging the next. You can rate examples to help us improve the quality of examples. Ignores the values from an observable sequence which are followed by another value before due time with the specified source and dueTime. bufferCount(bufferSize: number, startBufferEvery: number): Observable. Records the time interval between consecutive values in an observable sequence with the specified source and scheduler. (Defined by, Overloaded. Emits the given constant value on the output Observable every time the source Projects each source value to the same Observable which is flattened multiple distinctUntilChanged(compare: function): Observable. It would look something like this in time. Ignores source values for duration milliseconds, then emits the most recent ReplaySubject(Int32, TimeSpan, IScheduler), Aggregate(TAccumulate, Func), Buffer(TimeSpan, TimeSpan, IScheduler), Buffer(Func>), Buffer(IObservable, Func>), Catch(Func>), Distinct(Func, IEqualityComparer), DistinctUntilChanged(IEqualityComparer), DistinctUntilChanged(Func), DistinctUntilChanged(Func, IEqualityComparer), Do(Action, Action, Action), GroupBy(Func, IEqualityComparer), GroupBy(Func, Func), GroupBy(Func, Func, IEqualityComparer), GroupByUntil(Func, Func, IObservable>), GroupByUntil(Func, Func, IObservable>, IEqualityComparer), GroupByUntil(Func, Func, Func, IObservable>), GroupByUntil(Func, Func, Func, IObservable>, IEqualityComparer), GroupJoin, Join, MaxBy(Func, IComparer), MinBy(Func, IComparer), Multicast(ISubject), Multicast(Func>, Func, IObservable>), Publish(Func, IObservable>), Publish(Func, IObservable>, T), PublishLast(Func, IObservable>), Replay(Func, IObservable>), Replay(Func, IObservable>, IScheduler), Replay(Func, IObservable>, TimeSpan), Replay(Func, IObservable>, Int32), Replay(Func, IObservable>, TimeSpan, IScheduler), Replay(Func, IObservable>, Int32, IScheduler), Replay(Func, IObservable>, Int32, TimeSpan), Replay(Func, IObservable>, Int32, TimeSpan, IScheduler), Scan(TAccumulate, Func), Select(Func), SelectMany(IObservable), SelectMany(Func>), SelectMany(Func>), SelectMany(Func>, Func>, Func>), SelectMany(Func>, Func), SelectMany(Func>, Func), SequenceEqual(IObservable, IEqualityComparer), Subscribe(Action, Action), Subscribe(Action, Action, Action), Timeout(DateTimeOffset, IObservable), Timeout(TimeSpan, IObservable, IScheduler), Timeout(DateTimeOffset, IObservable, IScheduler), ToDictionary(Func, IEqualityComparer), ToDictionary(Func, Func), ToDictionary(Func, Func, IEqualityComparer), ToLookup(Func, IEqualityComparer), ToLookup(Func, Func), ToLookup(Func, Func, IEqualityComparer), Window(TimeSpan, TimeSpan, IScheduler), Window(Func>), Window(IObservable, Func>), Zip(IObservable, Func), Zip(IEnumerable, Func).
