CommentTemplate: A Code Generation Extension for Java

CommentTemplate (jamopp.org/CommentTemplate) is a code generation extension for Java built with JaMoPP.

eJava: Modeling Behaviour with Java Statements

eJava (jamopp.org/eJava) can be used to specify the behaviour of Ecore's EOperations with Java statements in separate files on the modelling level.

EMFCustomize: Customize Generated Code

EMFCustomize (emftext.org/EMFCustomize) allows the controlled mixing of generated and hand-written code when working with EMF Ecore models. It uses JaMoPP to refactor and merge generated and hand-written code.

JaMoPP Example Applications

To illustrate the potential of JaMoPP, we realized a set of example applications that profit from JaMoPP. The applications represent typical software modelling development activities (e.g., generating, analysing and visualising code), but also cover more advanced actions (e.g., composing programs or building product lines).

All applications use a common example that is a contact management application (cf. Figure 1). A ContactList is organised into several Groups, each containing a number of Contact. We distinguish Person and Company contacts. In addition information like Addresses, or Relationships between Contacts is managed.

Resource: Contact Management Application UML Model

The different applications, enumerated in the following, make use of different JaMoPP features:

• Java code generation by model transformation
  requires the printing of Java models to code.
• Model-based analysis of Java code
  requires JaMoPP's parsing and resolving capabilities.
• Graphical editing of Java programs
  requires both parsing and printing.
• Extending the Java language by metamodelling
  profits from the fact that JaMoPP is developed model-driven; that is, the metamodel and the EMFText syntax specification can be extended without breaking the JaMoPP tooling.
• Reusing Java statements for behaviour modelling
  defines a metamodel and a text syntax that extends both UML and Java and integrates them to use Java methods for UML behaviour definition.
• Applying a model-based visual tool on Java programs
  is enabled by the fact that JaMoPP is developed with EMFText that provides a text editor with the same integration into the Eclipse Platform as other (i.e., graphical) Eclipse model-editors.
• Model-driven Modernisation with JaMoPP and QVT
  on the example of migrating classical for loops to the new for-each style (introduced in Java 5) and converting anonymous classes to closures (planned for Java 8).
