Because all PADL creators are builders (as in the Builder design pattern) and must conform to the same interface padl.kernel.ICodeLevelModelCreator provided by PADL, it is simple to provide a unified entry point for all of them. Also, the creation of interesting models often require the additional steps of:

1. Annotating the models with information about lines of code;
2. Annotating the models with information about conditional statements;
3. Adding appropriate listeners (if desired);
4. Handling special files, such as Eclipse .project files or AOL CLD files;
5. …

So, the class padl.generator.helper.ModelGenerator in the project PADL Generator provides this entry point and should be used unless there are compelling reasons not to do so. The direct use of a creator will throw a warning at run-time.
