Example 73 with BundleEvent

Example 74 with BundleEvent

use of org.osgi.framework.BundleEvent in project smarthome by eclipse.

the class AutomationResourceBundlesEventQueue method run.

/**
 * When a new event for a bundle providing automation resources is received, this will causes a creation of a new
 * thread if there is no other created yet. If the thread already exists, then it will be notified for the event.
 * Starting the thread will cause the execution of this method in separate thread.
 * <p>
 * The general contract of this method <code>run</code> is invoking of the
 * {@link #processBundleChanged(BundleEvent)} method and executing it in separate thread.
 *
 * @see java.lang.Thread#run()
