Interface IExtensionRegistryFilter

public interface IExtensionRegistryFilter

Callback interface to filter out elements in the Extension Registry. Extensions that are attached to the RegistryFilter extension point and implement this interface will be called as necessary when a client operates on a named registry instance that matches their target specification.

1. Define an Extension for the RegistryFilter Extension Point for a named registry instance

     <extension point="org.eclipse.extensionregistry.RegistryFilter">
         <filter instance="AdminConsole*" class="com.ibm.ws.admin.AdminConsoleExtensionFilter"/>
     </extension>
 

2. Filter implements this IExtensionRegistryFilter interface

     package com.ibm.ws.admin;
     public class AdminConsoleExtensionFilter implements IExtensionRegistryFilter {
             :
     }
 

3. Host asks for a named instance of the registry to activate any associated filters

     IExtensionRegistry reg = factory.getExtensionRegistry( "AdminConsole" );
