Identificar posibles instancias de patrones de diseño utilizando técnicas de análisis estático, clustering, AST (Abstract Syntax Tree) o pattern matching

Abstract

Abstract:This degree work focuses on the analysis of source code in JAVA programming language, due to the need to validate the correct implementation of design patterns, they allow them to increase the quality of software solutions. Among the techniques evaluated, AST and pattern matching are the most predominant in the development of the prototype. The AST allowed through the compiler to identify the structure of the JAVA projects analyzed and from that, obtain the code characteristics such as methods, classes, packages, attributes and more. With the implementation of the pattern matching and procedures stored in the database, it was possible to compare the characteristics necessary for the implementation of each design pattern with the characteristics extracted from the analyzed code and thus determine whether the instance of the pattern was fully met or no. The prototype developed allows the percentage of implementation of the following design patterns to be identified: Singleton, Strategy / State, Composite, Observer and Facade, in addition to visualizing which classes are involved in the implementation of these design patterns.
