Class ProjectFileParser

java.lang.Object
  edu.rice.cs.drjava.project.ProjectFileParserFacade
      edu.rice.cs.drjava.project.ProjectFileParser

public class ProjectFileParser
extends ProjectFileParserFacade

This parser uses the s-expression parser defined in the util pacakge. The SExp tree given by the parser is interpreted into a ProjectFileIR that is given to the user. This class must also deal with different versions of the project file.

If at some point new information is to be stored in the project file, the following places in the code that need to changed:

If the new information pertains to a document, the DocFile class should be augmented to store the new info.

The interface for the DocumentInfoGetter should be expanded to allow for the new data to be retrieved.

Add a new clause to the else-if ladder in the FilePropertyVisitor.

Add the new information to the DocFile form the DocumentInfoGetter in the ProjectFileBuilder's addSourceDocument method.

If the change is at the top level, you must modify the evaluateExpression method in this parser and add the corresponding methods to the ProjectFileIR, ProjectFileIRImpl, and ProjectFileBuilder
