Description copied from interface: MethodEnhancer

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;
 }
 

Specified by:

enhance in interface MethodEnhancer

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
