Class LoggingInterceptorClassFactory

java.lang.Object
  org.apache.hivemind.service.impl.LoggingInterceptorClassFactory

public class LoggingInterceptorClassFactory
extends java.lang.Object

Factory for creation of interceptor classes that add logging capability to a service. The logging is based upon the Jakarta commons-logging toolkit, which makes it very transportable.

The interceptor will log entry to each method and exit from the method (with return value), plus log any exceptions thrown by the method. The logger used is the id of the service, which is not necessarily the name of the implementing class. Logging occurs at the debug level.
