Class Zip.ManyObservables<T,U>

java.lang.Object

hu.akarnokd.reactive4java.reactive.Zip.ManyObservables<T,U>

Type Parameters:

T - the common element type

U - the result element type

All Implemented Interfaces:

Observable<U>

Enclosing class:

Zip

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

Merges the values across multiple sources and applies the selector function.

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.
