intercept method calls (on the client and on the server side)
-------------------------------------------------------------
Key: XMLRPC-135
URL: https://issues.apache.org/jira/browse/XMLRPC-135
Project: XML-RPC
Issue Type: Improvement
Affects Versions: 3.0, 3.1
Reporter: Mario Linke
Priority: Critical
Fix For: 3.0, 3.1
This extension is to integrate cross-cutting concerns (AOP), how stopping the
time, logging or transform args and return value.
public interface Interceptor {
public void beforeMethodInvocation (InterceptorContext
pInterceptorContext);
public void afterMethodInvocation (InterceptorContext
pInterceptorContext);
public void onError (Throwable pThrowable);
}
public final class InterceptorContext {
private Method method = null;
private Object[] args = null;
private Object result = null;
}
InterceptorContext is analog to the XmlRpcRequest, extended to the result and
the method object.
Extend the XmlRpcController to register the Interceptors:
- addInterceptor
- removeInterceptor
- getInterceptorByNumber
and delegate before and after event:
by the client to XmlRpcWorker
by the server to the XmlRpcHandler
