Class OperatorMapPair<T,U,R>

java.lang.Object

rx.internal.operators.OperatorMapPair<T,U,R>

Type Parameters:

T - the type of items emitted by the source Observable

U - the type of items emitted by the derived Observables

R - the type of items to be emitted by this Operator

All Implemented Interfaces:

Func1<Subscriber<? super Observable<? extends R>>,Subscriber<? super T>>, Function, Observable.Operator<Observable<? extends R>,T>

public final class OperatorMapPair<T,U,R>
extends java.lang.Object
implements Observable.Operator<Observable<? extends R>,T>

An Observable.Operator that pairs up items emitted by a source Observable with the sequence of items emitted by the Observable that is derived from each item by means of a selector, and emits the results of this pairing.

Method Detail

convertSelector

public static <T,U> Func1<T,Observable<U>> convertSelector(Func1<? super T,? extends java.lang.Iterable<? extends U>> selector)

Creates the function that generates a Observable based on an item emitted by another Observable.

Parameters:

selector - a function that accepts an item and returns an Iterable of corresponding items

Returns:

a function that converts an item emitted by the source Observable into an Observable that emits the items generated by selector operating on that item
