combine

Operator

  combine — combine parallel pipeline branches into a single output

Synopsis

( ... ) ( ... ) | ...

Description

The implied combine operator merges inputs from multiple upstream branches of the pipeline into a single output. The order of values in the combined output is undefined.

You need not explicit reference the operator with any text. Instead, the mere existence of a merge point in the flow graph implies its existence and its semantics of undefined merge order.

Examples

Copy input to two pipeline branches and combine with the implied operator

fork
  ( pass )
  ( pass )
| sort this
