This page details the designs for adding custom interceptors declaratively into JBossCache.

UPDATED: See JBC3Config for details of all new config elements in JBoss Cache 3.x.

Configuration

The end goal is for users to be able to provide the following in their configurations:

<attribute name="CustomInterceptors">
   <config>
      <interceptor>
         <class>com.myCompany.MyInterceptor</class>
         <properties>
            x=y
            i=10
         </properties>
         <position first="true" ></position>
         <!-- could also be either of: 
            <position last="true" ></position>
            <position index="4" ></position>
            <position before="org.jboss.cache.interceptors.CallInterceptor" ></position>
            <position after="org.jboss.cache.interceptors.CallInterceptor" ></position>
         -->
      </interceptor>
      ...
   </config>
</attribute>

Custom interceptor design

• Custom interceptors must extend org.jboss.cache.interceptors.CommandInterceptor.

• Custom interceptors must declare a public, empty constructor to enable construction.

• Custom interceptors will have any properties declared passed in as a Properties object, in CommandInterceptor's setProperties(Properties p) method.

• Custom interceptors will not be able to participate in any lifecycle or injection (at this time).  Annotating methods as @Inject, @Start, @Stop or @Destroy will have no effect.
