Class Zip.TwoObservable<T,U,V>

java.lang.Object

hu.akarnokd.reactive4java.reactive.Zip.TwoObservable<T,U,V>

Type Parameters:

T - the left observable's element type

U - the right observable's element type

V - the result element type

All Implemented Interfaces:

Observable<V>

Enclosing class:

Zip

public static class Zip.TwoObservable<T,U,V>
extends java.lang.Object
implements Observable<V>

Pairwise merges the two observable sequences and emits the value by the selector.

The resulting sequence terminates if no more pairs can be established, i.e., streams of length 1 and 2 zipped will produce only 1 item.

Exception semantics: errors from the source observable are propagated as-is.
