Detailed Description

For each item from this observable until on_next occurs on the trigger observable or until the specified time, emit them from the new observable that is returned. take_until takes (TriggerObservable, optional Coordination) or (TimePoint, optional Coordination)

Template Parameters

TriggerSource	the type of the trigger observable.
TimePoint	the type of the time interval.
Coordination	the type of the scheduler (optional).

Parameters

t	an observable whose first emitted item will stop emitting items from the source observable.
when	a time point when the returned observable will stop emitting items.
cn	the scheduler to use for scheduling the items (optional).

Returns

An observable that emits the items emitted by the source observable until trigger observable emitted or the time runs out.

Sample Code

    auto source = rxcpp::observable<>::interval(std::chrono::milliseconds(10)).take(7);
    auto trigger = rxcpp::observable<>::timer(std::chrono::milliseconds(25));
    auto values = source.take_until(trigger);
    values.
        subscribe(
            [](long v){printf("OnNext: %ld\n", v);},
            [](){printf("OnCompleted\n");});

OnNext: 1
OnNext: 2
OnNext: 3
OnCompleted

Sample Code

    printf("[thread %s] Start task\n", get_pid().c_str());
    auto source = rxcpp::observable<>::interval(std::chrono::milliseconds(10)).take(7).map([](long v){
        printf("[thread %s] Source emits, value = %ld\n", get_pid().c_str(), v);
        return v;
    });
    auto trigger = rxcpp::observable<>::timer(std::chrono::milliseconds(25)).map([](long v){
        printf("[thread %s] Trigger emits, value = %ld\n", get_pid().c_str(), v);
        return v;
    });
    auto values = source.take_until(trigger, rxcpp::observe_on_new_thread());
    values.

            [](){printf("[thread %s] OnCompleted\n", get_pid().c_str());});
    printf("[thread %s] Finish task\n", get_pid().c_str());
