Detailed Description

Return an observable that emits connected, non-overlapping windows of items from the source observable that were emitted during a fixed duration of time or when the window has reached maximum capacity (whichever occurs first), on the specified scheduler.

Template Parameters

Duration	the type of time intervals.
Coordination	the type of the scheduler (optional).

Parameters

period	the period of time each window collects items before it is completed and replaced with a new window.
count	the maximum size of each window before it is completed and new window is created.
coordination	the scheduler for the windows (optional).

Returns

Observable that emits connected, non-overlapping windows of items from the source observable that were emitted during a fixed duration of time or when the window has reached maximum capacity (whichever occurs first).

Sample Code

    int counter = 0;
    auto int1 = rxcpp::observable<>::range(1L, 3L);
    auto int2 = rxcpp::observable<>::timer(std::chrono::milliseconds(50));
    auto values = int1.
        concat(int2).
        window_with_time_or_count(std::chrono::milliseconds(20), 2, rxcpp::observe_on_event_loop());
    values.
        as_blocking().
        subscribe(
            [&counter](rxcpp::observable<long> v){
                int id = counter++;
                printf("[window %d] Create window\n", id);
                v.subscribe(
                    [id](long v){printf("[window %d] OnNext: %ld\n", id, v);},
                    [id](){printf("[window %d] OnCompleted\n", id);});
