====== PADL Generator ======

In general, a code-level model can be obtain for a system through reverse-engineering/parsing using:

<code>
final ICodeLevelModel codeLevelModel =
   Factory.getInstance().createCodeLevelModel(<Name>);
codeLevelModel.create(
   new <A>Creator(
       <FileRepository>.getInstance(),
       new String[] { <Some files> }), <Recurse in directories>);
</code>

where:
    * <Name> can be any String;
    * <A>Creator is any class implementing the ICodeLevelModelCreator interface. A creator is the concrete parser or reverse-engineering algorithm that builds a PADL model from some files;
    * <FileRepository> is any class implementing the IFileRepository interface. A file repository allows the meta-model and the creator to access necessary PADL resources (constituents, analyses, etc.) in a platform-independent way;
    * <Some files> are any String pointing towards the files/directories to be parsed, as required by the creator;
    * <Recurse in directories> is a Boolean flag that allow you to specify only the top most directory of a set of source files.

Because all PADL creators are builders (as in the Builder design pattern) and 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:
  - Annotating the models with information about lines of code;
  - Annotating the models with information about conditional statements;
  - Adding appropriate listeners (if desired);
  - Handling special files, such as Eclipse ''.project'' files or AOL CLD files;
  - ...

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.
