Commands reaching this pipe pair are transformed into a sequence of commands for the next or events for the previous stage.
Commands reaching this pipe pair are transformed into a sequence of commands for the next or events for the previous stage.
Throwing exceptions within this method will abort processing of the whole pipeline which this pipe pair is part of.

Management commands are sent to all stages in a broadcast fashion, conceptually in parallel (but not actually executing a stage reentrantly in case of events or commands being generated in response to a management command).

Wrap a single command for efficient return to the pipeline’s machinery.
Wrap a single command for efficient return to the pipeline’s machinery. This method avoids allocating a scala.util.Right and an java.lang.Iterable by reusing one such instance within the AbstractPipePair, hence it can be used ONLY ONCE by each pipeline stage. Prototypic and safe usage looks like this:
final MyResult result = ... ; return singleCommand(result);

Wrap a single event for efficient return to the pipeline’s machinery.
Wrap a single event for efficient return to the pipeline’s machinery. This method avoids allocating a scala.util.Left and an java.lang.Iterable by reusing one such instance within the AbstractPipePair, hence it can be used ONLY ONCE by each pipeline stage. Prototypic and safe usage looks like this:
final MyResult result = ... ; return singleEvent(result);
PipelineContext#singleEvent
A convenience type for expressing a AbstractPipePair which has the same types for commands and events.
