Detailed Description

A wrapper for pipeline actions.

Pipeline actions, unlike normal events, do not transport data but execution instructions to be executed.

Note

On pipelines, actions unlike events, when submitted are always executed synchronously, meaning that when the call returns all handlers already processed it. Actions are good for executing start and stop actions for example, but also for configuring handlers.
