All Flow Control Reference
Purpose: Sends the same message to multiple target message processors.
Minimum Configuration: None
Discussion: Use the All Flow Control to route or broadcast the same message to more than one processor component.
In many cases, All sends messages to endpoints. If the endpoints has a filter associated to it, then the message must pass through the filtering criteria in order for the endpoint to receive it.
If the targets receiving messages from the All Flow Control also return messages, then these return messages, if any, are suggested together and collectively from the response.
