Class OperatorGroupBy<T,K,V>

java.lang.Object

com.github.davidmoten.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:

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

public final class OperatorGroupBy<T,K,V>
extends Object
implements rx.Observable.Operator<rx.observables.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.
