Installation
-
Install Java 2 Runtime Environment, Standard Edition 1.5.0 or newer
You can download it from http://java.com/en/index.jsp -
Download the Design Pattern detection Tool (version 4.13 - build 25/02/2020)
In order to avoid Heap size OutOfMemoryError, execute in console java -Xms32m -Xmx512m -jar pattern4.jar
Usage
- You must first select the root of the project package. Only class files (bytecode files) are necessary for the project analysis.
- Then select the pattern(s) to be detected from the pattern list.
- You can use some of the Huston design pattern Java demos for testing the tool.
- You can find a guide explaining how to add your own custom design pattern definition(s) in the tool.
Proxy Variation
The design pattern reported by the tool as Proxy2 is actually a variation of Proxy pattern.
However, this Proxy variation is structurally more similar to Decorator pattern than Proxy pattern, since Proxy role has an association to Subject role (named subject)
and method Request() declared in Proxy invokes an abstract method having the same signature through subject association
(as exactly happens between Decorator and Component roles in Decorator pattern).
The differences between Decorator pattern and this Proxy variation are: a) Decorator role is abstract while Proxy role is concrete,
b) Proxy role initializes its association to Subject role with a reference to an object of RealSubject role which is instantiated inside the constructor of Proxy role.
This kind of Proxy variation has been reported by Gunter Kniesel and Alex Binun from University of Bonn.
ChangeLog
- Supported the detection of the Enum Singleton variant proposed by Joshua Bloch only if it has one named constant. (version 4.13)
- Adapter and Command pattern instances are reported separately. State and Strategy pattern instances are reported separately (version 4.12)
- Added support for Chain of Responsibility design pattern (version 4.11)
- Improved performance in the generation of subsystems for the detection of design patterns residing in two inheritance hierarchies (version 4.10)
- Added support for Bridge design pattern (version 4.9)
- Test classes are automatically excluded from the analysis (version 4.9)
- Updated ASM library to version 5.1 (version 4.8)
- Added behavioral information for the State/Strategy and Adapter/Command design patterns (version 4.7)
- Excluded enum types from being reported as Singleton instances (version 4.6)
- Fixed a bug related with the handling of composite generic types (bug reported by Lin-Chieh Wen from the Dept. of Information Engineering & Computer Science, Feng Chia University, Tai-Chung, Taiwan, R.O.C.) (version 4.5)
- Report of additional pattern roles corresponding to methods and fields (version 4.4)
- The Subject role in Observer pattern should also contain a detach method used for unregistering Observers (version 4.3)
- In Visitor pattern visitConcreteElement methods may also have Element type as parameter instead of ConcreteElement types (version 4.2)
- Array types are included in the analysis for the identification of Composite and Observer pattern instances (version 4.1)
- Fixed the problem concerning the distinction of Observer from Composite pattern (version 4)
- Add support for Proxy design pattern (version 4)
- Export detected design pattern instances to XML format (version 2)
- Detection of all design patterns with a single click (version 2)
- Console version (version 2)
Execution: java -Xms32m -Xmx512m -jar pattern4.jar -target "C:\foo\myclasses" -output "C:\foo\output.xml"
