public interface MethodEnhancer

Implementations of this interface will be used to enhance methods with profiling information/ callbacks. TODO This can be moved, I think it's also useful outside the profile package.

Method Detail

enhance

DynamicMethod enhance(String name,
                    DynamicMethod delegate)

Will be called with a method which should be enhanced. e.g. with information or callback invocations required by the profiling. In most cases you don't want to profile all methods, just the methods of your own code. So you can add a simple filter here

 if( isMyCode( delegate ) ) {
     return new ProfilingDynamicMethod( delegate );
 } else {
     return delegate;
 }
 

Parameters:

name - the name of the given delegate

delegate - the method to enhance

Returns:

the enhanced method. if nothing is to be done, the delegate itself can be returned
