Class LoggingAspect

java.lang.Object

com.goldencode.util.LoggingAspect

public class LoggingAspect
extends java.lang.Object

The class implements Aspect logging of a program execution. The idea is to annotate program entities and so get meaningful logging output with minimum effort. To use, annotate any method with LogExecution, recompile and voilà! The log output will contain the method execution, together with the target instance toString() and all the parameters and return value.
