Example 1 with NamingEvent

use of javax.naming.event.NamingEvent in project wildfly by wildfly.

the class NamingEventCoordinator method fireEvent.

     * Fire a naming event.  An event will be created with the provided information and sent to each listener that matches
     * the target and scope information.

     * @param context The event context generating the event.
     * @param name The target name the event represents
     * @param existingBinding The existing binding at the provided name
     * @param newBinding The new binding at the provided name
     * @param type The event type
     * @param changeInfo The change info for the event
     * @param scopes The scopes this event should be fired against
