public void fireDbAttributeDisplayEvent(AttributeDisplayEvent e) {
    boolean changed = !Arrays.equals(e.getAttributes(), currentState.dbAttrs);
    if (changed) {
        if (e.getEntity() != currentState.dbEntity) {

Example 37 with EventListener

use of java.util.EventListener in project nutzboot by nutzam.

Example 38 with EventListener

use of java.util.EventListener in project litiengine by gurkenlabs.

the class ReflectionUtilities method getEvents.

/**

 * naming conventions for event subscription (i.e. the method name starts with one of the prefixes "add" or "on".
 *
 * @param type
 *          The type to inspect the events on.
 * @return All methods on the specified type that are considered to be events.
