MaintainJ

Sat, 21 Oct 2006 12:00:54 GMT

Eclipse plug-in for generating run-time UML sequence and class diagrams for a use case.
MaintainJ logs runtime method execution sequence to a file and uses that trace file to render sequence and class diagrams. MaintainJ Instrumentation Wizard instruments a Java/J2EE application and MaintainJ UML Editor renders sequence and class diagram from the trace file.

MaintainJ helps you to find out what happens in an application when you run a use case. It can be used to understand large, complex Java code.

Features include:
- Generate runtime UML sequence and class diagrams for a given use case on demand
- Source untouched: The application code is untouched; application is rebuilt using AspectJ compiler to capture the method execution sequence at runtime
- Aspects for instrumenting the code are generated by wizard
- Collapsible calls: Method calls in sequence diagram are collapsible. Developers can explore a sequence diagram by collapsing and expanding calls as necessary.
- Focused Diagrams: Only application classes in specified packages are shown in diagrams. All loop calls and recursive calls are removed from sequence diagrams.
- Instrument Java applications or Jar files in Eclipse using AJDT or outside Eclipse using Ant. Generate trace files by running the application with instrumented class or jar files.
- Multi-threaded application support: MaintainJ logs separate trace files for each thread in one use case.
- JUnit integration
- Eclipse Integration: Double click a call or class to open matching method or class in Eclipse.
- Print or export diagrams as JPEG images.

Spoon

Thu, 07 Sep 2006 20:50:28 GMT

Java program processor that provides a Java metamodel where any program element (classes, methods, fields, statements, expressions...) can be accessed both for reading and modification.
Spoon can be used on validation purpose, to ensure that your programs respect some programming conventions or guidelines, or for program transformation, by using a pure-Java template engine.

Spoon provides an Eclipse plugin (SpoonJDT) that allows for integration of Spoon within the Eclipse environment. With SpoonJDT, a set of validations and transformations packaged as a Spoonlet can occur on the fly and the reports are well-integrated into the Eclipse JDT.

Relief

Thu, 28 Jun 2007 12:50:50 GMT

Tool that uses visual characteristics to describe entities and relations of a Java project: size, color, distance to the center, height and links.
Relying on our ability to deal with real objects by examining their shape, size or relative place in space, Relief gives a "physical" view on Java packages, types and fields and their relationships.
This makes it possible to grasp coherence and robustness of a project by detecting dead code, unwanted relations, strong coupling between entities, use of external libraries, etc.
