rx.operators

Class OperatorCache<T>

java.lang.Object

rx.operators.OperatorCache<T>

Type Parameters:

T - the cached value type

All Implemented Interfaces:

Action, Action1<Subscriber<? super T>>, Function, Observable.OnSubscribe<T>

public final class OperatorCache<T>
extends java.lang.Object
implements Observable.OnSubscribe<T>

This method has similar behavior to Observable.replay() except that this auto-subscribes to the source Observable rather than returning a connectable Observable.

This is useful with an Observable that you want to cache responses when you can't control the subscribe/unsubscribe behavior of all the Observers.

NOTE: You sacrifice the ability to unsubscribe from the origin when you use this operator, so be careful not to use this operator on Observables that emit infinite or very large numbers of items, as this will use up memory.
