Class ConcurrentExecutionTracker

java.lang.Object

org.eclipse.microprofile.fault.tolerance.tck.util.ConcurrentExecutionTracker

@Dependent
public class ConcurrentExecutionTracker
extends Object

Utility bean to track the number of concurrent executions of a method

The method being tracked needs to call executionStarted() when it starts and executionEnded() when it's about to end.

 try {
     tracker.executionStarted();
     // whatever the method is meant to do
 }
 finally {
     tracker.executionEnded()
 }
 

Another method can then call waitForRunningExecutions(int) to wait for the expected number of executions to start.
