This is a technical documentation on PTIDEJ¹ entry-points.
PTIDEJ stands for Pattern Traces Identification, Detection, and Enhancement in Java.
PTIDEJ is mainly written by Yann-Gaël Guéhéneuc.
      Many thanks to Hervé Albin-Amiot for the Pattern Description Language and PatternsBox;
      to Matthieu Bacqueville, Nicolas Benoit, Jean-Sébastien Brunner and Christian Gossart for the implementation within Eclipse.
We welcome all feedback.

PTIDEJ is a tool for object-oriented software design quality. PTIDEJ shall allow:

• To define design patterns as first-class entities.
• To detect these patterns in any source code. The results of the detection are both the complete and distorted versions of the design patterns.
• To transforme the source code according to the advices given by the design patterns found in the source code.

PTIDEJ offers several distinctive entry-points:

• An entry point to the pattern repository. The singleton class patterns.PatternRepository offers methods to list and to manipulate known patterns abstract models (see Gamma et al. [1]).
• An entry point to the reverse-engineering algorithms. The class patterns.PatternIntrospector offers methods to create a model from a list of class-files. The jut.viewer.core.ProjectLoaderViewerPanel.build() method demonstrates a typical use of the patterns.PatternIntrospector class. The idea is to construct an instance of the PatternIntrospector class, to use the patterns.util.TypeLoader class to build instances of class ClassFile representing the class files in a directory, and to build the model of the class files using the patterns.PatternIntrospector.build(ClassFile[]) method.
• An entry point to the graphic framework. The jtu.ui.kernel.Pattern class offers methods to build a graphical representation of a pattern (subclass of class patterns.kernel.Pattern) or of a model of class files (class PatternIntrospector). The jtu.viewer.core.ViewerPanel.setCurrentPattern(patterns.kernel.Pattern) method demonstrates a typical use of the jtu.ui.kernel.Pattern class. An instance of class jtu.ui.kernel.Pattern is created with a given instance of a (subclass of) class patterns.kernel.Pattern, a given instance of a concrete factory for the graphic primitives (either jtu.ui.primitive.awt.PrimitiveFactory for AWT primitives or jtu.ui.primitive.swt.PrimitiveFactory for SWT primitives), and a given layout algorithm. The instance of class jtu.ui.kernel.Pattern is then built and displayed in a given canvas (either jtu.viewer.core.AWTCanvas for AWT or jtu.viewer.eclipse.ui.SWTCanvas for SWT).

¹ PTIDEJ stands for "breakfast" (in french argot) and is pronounced "tE-dAzh (see Pterodactyl and Déjà vu).
