示例1: EventHandler

public EventHandler(Object target, String action, String eventPropertyName,
String listenerMethodName) {
if (target == null || action == null) {
throw new NullPointerException();
}
this.target = target;
this.action = action;
this.eventPropertyName = eventPropertyName;
this.listenerMethodName = listenerMethodName;
this.context = AccessController.getContext();
}
示例2: create
import com.googlecode.openbeans.EventHandler; //導入依賴的package包/類
@SuppressWarnings("unchecked")
