Class HttpAdapterInvokeAdapter

java.lang.Object
oracle.panama.adapter.http.event.HttpAdapterInvokeAdapter

All Implemented Interfaces:

java.util.EventListener, HttpAdapterInvokeListener

public abstract class HttpAdapterInvokeAdapter

extends java.lang.Object

implements HttpAdapterInvokeListener

An abstract adapter class for receiving "HttpAdapterInvoke" events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Extend this class to create a HttpAdapterInvokeInvokeEvent listener and override the methods for the events of interest. (If you implement the HttpAdapterInvokeListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)

The subclasses must implement the Singleton design pattern and define a method getInstance. Here is an example

 public class HttpAdapterInvokeListenerImpl extends HttpAdapterInvokeAdapter {
     private static HttpAdapterInvokeListener instance;
     public static synchronized HttpAdapterInvokeListener getInstance() {
         if (instance == null) {
             instance = new HttpAdapterInvokeListenerImpl();
         }
         return instance;
     }

     ...

 }
