Class OperatorSequenceEqual

java.lang.Object

rx.internal.operators.OperatorSequenceEqual

public final class OperatorSequenceEqual
extends java.lang.Object

Returns an Observable that emits a single Boolean value that indicates whether two source Observables emit sequences of items that are equivalent to each other.

Modifier and Type	Method and Description
static <T> Observable<java.lang.Boolean>	sequenceEqual(Observable<? extends T> first, Observable<? extends T> second, Func2<? super T,? super T,java.lang.Boolean> equality) Tests whether two Observable sequences are identical, emitting true if both sequences complete without differing, and false if the two sequences diverge at any point.

Method Detail

sequenceEqual

public static <T> Observable<java.lang.Boolean> sequenceEqual(Observable<? extends T> first,
                                              Observable<? extends T> second,
                                              Func2<? super T,? super T,java.lang.Boolean> equality)

Tests whether two Observable sequences are identical, emitting true if both sequences complete without differing, and false if the two sequences diverge at any point.

Parameters:

first - the first of the two Observables to compare

second - the second of the two Observables to compare

equality - a function that tests emissions from each Observable for equality

Returns:

an Observable that emits true if first and second complete after emitting equal sequences of items, false if at any point in their sequences the two Observables emit a non-equal item.
