Class ReplayingShare<T>

java.lang.Object

com.jakewharton.rx.ReplayingShare<T>

All Implemented Interfaces:

io.reactivex.FlowableTransformer<T,T>, io.reactivex.ObservableTransformer<T,T>

public final class ReplayingShare<T>
extends Object
implements io.reactivex.ObservableTransformer<T,T>, io.reactivex.FlowableTransformer<T,T>

A transformer which combines the replay(1), publish(), and refCount() operators.

Unlike traditional combinations of these operators, `ReplayingShare` caches the last emitted value from the upstream observable or flowable *only* when one or more downstream subscribers are connected. This allows expensive upstream sources to be shut down when no one is listening while also replaying the last value seen by *any* subscriber to new ones.
