Detailed Description

Returns an Observable that emits true if every item emitted by the source Observable satisfies a specified condition, otherwise false. Emits true if the source Observable terminates without emitting any item.

Template Parameters

Predicate

the type of the test function.

Parameters

p	the test function to test items emitted by the source Observable.

Returns

Observable that emits true if every item emitted by the source observable satisfies a specified condition, otherwise false.

Sample Code

    auto values = rxcpp::observable<>::from(1, 2, 3, 4, 5).all([](int n) { return n < 6; });
    values.
            subscribe(
            [](bool v) { printf("OnNext: %s\n", v ? "true" : "false"); },
            []() { printf("OnCompleted\n"); });

OnNext: true
OnCompleted
