Examples of org.zkoss.zk.ui.event.EventThreadCleanup

org.zkoss.zk.ui.event.EventThreadCleanup
Used to clean the event processing thread.
How this interface is used.
1. First, you specify a class that implements this interface in WEB-INF/zk.xml as a listener.
2. Then, an instance of the specified class is constructed and {@link #cleanup}is invoked when the event processing thread has processed an event, and then {@link #complete} of the same instance is called in the servletthread.
Thus, the typical use is to cleaup un-closed transactions when {@link #cleanup} is called. @author tomyeh


    final List cleanups = new LinkedList();
    for (int j = 0; j < ary.length; ++j) {
      final Class klass = (Class)ary[j];
      try {
        final EventThreadCleanup cleanup =
          (EventThreadCleanup)klass.newInstance();
        cleanup.cleanup(comp, evt, errs);
        cleanups.add(cleanup);
      } catch (Throwable t) {
        if (errs != null) errs.add(t);
        if (!silent)
          log.error("Failed to invoke "+klass, t);
