Concat

object Concat

Takes two streams and outputs an output stream formed from the two input streams by consuming one stream first emitting all of its elements, then consuming the second stream emitting all of its elements.

Note that a junction instance describes exactly one place (vertex) in the FlowGraph that multiple flows can be attached to; if you want to have multiple independent junctions within the same FlowGraph then you will have to create multiple such instances.

Emits when the current stream has an element available; if the current input completes, it tries the next one

Backpressures when downstream backpressures

Completes when all upstreams complete

Cancels when downstream cancels

    Create a new anonymous Concat vertex with the specified input types.

    Create a new anonymous Concat vertex with the specified input types. Note that a Concat instance can only be used at one place (one vertex) in the FlowGraph. This method creates a new instance every time it is called and those instances are not equal.
