Class ResourceListenerFactory

This class is used by a module to help make a REST Resource more extensible through the use of a listener pattern. Example usage:

In MODA:

 @Path("/my-resource")
 public class MODARestResource extends BaseResource {
   
   @POST
   @Path("/update")
   public JSONObject update(@FormParam("sysId") Long sysId) {
     List listeners = ResourceListenerFactory.get(MODARestResourceListener.class);
     for(MODARestResourceListener listener : listeners) {
       listener.preUpdate(sysId);
     }
     
     ...
     
     for(MODARestResourceListener listener : listeners) {
       listener.postUpdate(sysId);
     }
   }
   
 }
 
 public abstract class MODARestResourceListener {
   
   public void preUpdate(Long sysId) { }
   public void postUpdate(Long sysId) { }
   
 }
 

In MODB (which depends on MODA):

 @ResourceListener("com.onenetwork.moda.rest.MODARestResourceListener")
 public class MODBRestResourceListener extends MODARestResourceListener {
   
   public void preUpdate(Long sysId) {
     ...
   }
   
   public void postUpdate(Long sysId) {
     ...
   }
   
 }
