public static class SwitchMapToOperator

Inheritance

System.Object

SwitchMapToOperator

Methods

SwitchMapTo<TSource, TResult>(Observable<TSource>, Observable<TResult>)

Projects every value from source to the same innerObservable, regardless of the source value, switching to a fresh subscription every time source emits (tearing down the previous one, even if still active). Equivalent to source.SwitchMap(_ => innerObservable).

public static Observable<TResult> SwitchMapTo<TSource, TResult>(this Observable<TSource> source, Observable<TResult> innerObservable)

Parameters

source Observable<TSource>

The source sequence.

innerObservable Observable<TResult>

The observable to switch to for every value emitted by source.

Returns

Observable<TResult>

An observable that emits the values of only the most recent subscription to innerObservable.

Type Parameters

TSource

The type of values emitted by source.

TResult

The type of values emitted by innerObservable.

Remarks

Marked @deprecated upstream (in favor of switchMap(() => result)) but still present in rxjs 7.8.2, so it is ported here too. Like SwitchMapOperator, this does not port rxjs's deprecated resultSelector parameter — apply .Map(...) to the result for a projection.
