Damon,
Here you go! It's almost a direct rip off from the example logging
interceptor on the web site.
package com.mckesson.adept.hivemind;
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Proxy;
import java.util.List;
import org.apache.hivemind.InterceptorStack;
import org.apache.hivemind.ServiceInterceptorFactory;
import org.apache.hivemind.internal.Module;
public class TimerInterceptorFactory implements ServiceInterceptorFactory {
public TimerInterceptorFactory() {
super();
}
public void createInterceptor(InterceptorStack stack,
Module invokingModule, List parameters) {
InvocationHandler handler = new TimerInvocationHandler(stack.peek(),
stack.getServiceInterface());
Object interceptor = Proxy.newProxyInstance(invokingModule
.getClassResolver().getClassLoader(), new Class[]{stack
.getServiceInterface()}, handler);
stack.push(interceptor);
}
}
package com.mckesson.adept.hivemind;
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import com.mckesson.common.util.Timer;
public class TimerInvocationHandler implements InvocationHandler {
private String className;
private Object inner;
public TimerInvocationHandler(Object inner, Class intf) {
super();
this.inner = inner;
this.className = inner.getClass().getName();
if (this.className.startsWith("$")) {
this.className = intf.getName();
}
this.className += '.';
}
public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable {
String timer = this.className + method.getName();
Timer.startTimer(timer);
try {
Object result = method.invoke(this.inner, args);
return result;
}
catch (InvocationTargetException ex) {
throw ex.getTargetException();
}
finally {
Timer.stopTimer(timer);
}
}
}

Richard,
Could you please distribute your reflection/proxy - based interceptor?
(Or at least send me a version?)
Cheers, ~dmr
