Version: 3.2.2 (fraclet-java)
Released: March 19th, 2009
  • Fraclet is a Java programming model for the Fractal component model. Fraclet exploits the principles of annotation-oriented programming (@OP) to implement this model. Thus, Fraclet leverages the process of writing a Fractal application by providing a set of annotations, which reduces the amount of code written by developers.

    The current implementation of Fraclet (3.2) provides the following functionalities:

    • Extensive set of Java5 annotations dealing with all the features of Fractal,
    • Compile-time transformation of the Java5 annotations using the Spoon source code analysis and transformation tool,
      • Insertion of the callback interfaces into the source code (BindingController, AttributeController, LifeCycleController),
      • Generation of the Fractal ADL descriptors for primitive components,
      • Generation of the Fractal ADL abstract descriptors for composite components.


  • If you never used Fraclet before, read the user guide;
  • If you were using a former version of Fraclet, read the migration guide.


To start using Fraclet, you can either:


Former versions

Two versions of the Fraclet framework were formerly developed:

These versions are still available, but no more supported. Please read the Fraclet migration guide to migrate to the new annotation set.
