Class GroupByUntil.Default<K,V,T,D>

java.lang.Object

hu.akarnokd.reactive4java.reactive.GroupByUntil.Default<K,V,T,D>

Type Parameters:

T - the source element type

K - the key type

V - the value type

D - the duration element type, ignored

All Implemented Interfaces:

Observable<GroupedObservable<K,V>>

Enclosing class:

GroupByUntil

public static final class GroupByUntil.Default<K,V,T,D>
extends java.lang.Object
implements Observable<GroupedObservable<K,V>>

Groups the source sequence of Ts until the specified duration for that group fires.

The key comparison is done by the Object.equals() semantics of the HashMap.

Exception semantics: if the source throws an exception, all active groups will receive the exception followed by the outer observer of the groups.

Completion semantics: if the source finishes, all active groups will receive a finish signal followed by the outer observer.
