Design Patterns are typically encoded into Java code in an ad-hoc fashion. They are either embedded into the names of the classes or written into the Javadocs. Unfortunately it is impossible to accurately determine a pattern based solely on the class structure without knowing the intent of the code author. JPatterns is a collection of annotations that make it easy to communicate the use of (Design)Patterns within your code to your fellow developers and your future self.
