Unnumbered Development Release

This will install a new unnumbered (same release number) "development" release locally:

cdevents
mvn clean install; ./bin/install -f

How to add New Commands

This is how you code new clad commands:

Clad User Manual

A few things to keep in mind:

  • The pipeline is initialized by the runtime, but there is no queue between the event processor and terminator. The command must install it.
  • The command executes on the main thread and might exit (and kill the JVM in the process) before the terminator had a chance to process its queue. Always register an EndOfStreamListerer with the terminator and wait on the main thread until that listener is notified.

Terminator terminator = runtime.getTerminator();

final CountDownLatch rendezVous = new CountDownLatch(1);

terminator.addEndOfStreamListener(new EndOfStreamListener() {
   @Override
   public void eventStreamEnded() {
        rendezVous.countDown();
    }
});

// ...

//
// wait until terminator finishes its queue
//
rendezVous.await();

or, better yet:

runtime.waitForEndOfStream();
