Class AspectPattern

  org.jcoderz.commons.tracing.AspectPattern

public class AspectPattern
extends Object

This class allows to match aspectJ like patterns with the java internal class representation.

The following limitations / specialties should be considered:

• the '+' is not supported so you can not check for classes implementing a certain interface.
• throws is not supported as a part of the matching signature.
• The pattern is based on the information you can find at aspectwerkz
• The method name new can be used to refer to the constructor (<init>) and to the class ( <clinit>) initialization.

TODO: Javadoc TODO: Support '+' for inheritance
