Example 76 with Closure

use of groovy.lang.Closure in project groovy-core by groovy.

the class JmxEventListener method handleNotification.

/**
 * This is the implemented method for NotificationListener.  It is called by an event emitter to dispatch
 * JMX events to listeners.  Here it handles internal JmxBuilder events.
 *
 * @param notification the notification object passed to closure used to handle JmxBuilder events.
 * @param handback     - In this case, the handback is the closure to execute when the event is handled.

    Map event = (Map) handback;
