| + | ====== 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. | ||
