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.
