Merge

object Merge

Merge several streams, taking elements as they arrive from input streams (picking randomly when several have elements ready).

When building the FlowGraph you must connect one or more input sources and one output sink to the Merge vertex.

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 one of the inputs has an element available

Backpressures when downstream backpressures

Completes when all upstreams complete

Cancels when downstream cancels
