Detailed Description

Simple class that adds an entry to the Transient Event Store to record that the processing flow triggered its execution.

The main use case is to replace OutputStream instances appearing in the normal processing flow of workers in GaudiMP jobs. The information is then passed to the writer process where an instance of ReplayOutputStream will trigger the actual writing.
