#include <FWCore/ServiceRegistry/interface/ActivityRegistry.h>

Detailed Description

Description: Registry holding the signals that Services can subscribe to

Usage: Services can connect to the signals distributed by the ActivityRegistry in order to monitor the activity of the application.

There are unit tests for the signals that use the Tracer to print out the transitions as they occur and then compare to a reference file. One test does this for a SubProcess test and the other for a test using unscheduled execution. The tests are in FWCore/Integration/test: run_SubProcess.sh testSubProcess_cfg.py run_TestGetBy.sh testGetBy1_cfg.py testGetBy2_cfg.py
