Detailed Description

For each item from this observable subscribe to one at a time, in the order received. For each item from all of the given observables deliver from the new observable that is returned.

There are 2 variants of the operator:

• The source observable emits nested observables, nested observables are concatenated.
• The source observable and the arguments v0...vn are used to provide the observables to concatenate.

Template Parameters

Coordination	the type of the scheduler (optional).
Value0	... (optional).
ValueN	types of source observables (optional).

Parameters

cn	the scheduler to synchronize sources from different contexts (optional).
v0	... (optional).
vn	source observables (optional).

Returns

Observable that emits the items emitted by each of the Observables emitted by the source observable, one after the other, without interleaving them.

Sample Code

    auto o1 = rxcpp::observable<>::range(1, 3);
    auto o2 = rxcpp::observable<>::just(4);
    auto o3 = rxcpp::observable<>::from(5, 6);
    auto base = rxcpp::observable<>::from(o1.as_dynamic(), o2, o3);
    auto values = base.concat();
    values.
        subscribe(
            [](int v){printf("OnNext: %d\n", v);},
            [](){printf("OnCompleted\n");});
