Package rx.internal.operators

Class OperatorGroupBy<T,K,V>

java.lang.Object

rx.internal.operators.OperatorGroupBy<T,K,V>

Type Parameters:

K - the key type

T - the source and group value type

V - the value type of the groups

All Implemented Interfaces:

Func1<Subscriber<? super GroupedObservable<K,V>>,Subscriber<? super T>>, Function, Observable.Operator<GroupedObservable<K,V>,T>

public final class OperatorGroupBy<T,K,V>
extends java.lang.Object
implements Observable.Operator<GroupedObservable<K,V>,T>

Groups the items emitted by an Observable according to a specified criterion, and emits these grouped items as Observables, one Observable per group.
