DeclarationScanner

public class DeclarationScanner extends Object implements DeclarationVisitor
A visitor for declarations that scans declarations contained within the given declaration. For example, when visiting a class, the methods, fields, constructors, and nested types of the class are also visited.

To control the processing done on a declaration, users of this class pass in their own visitors for pre and post processing. The preprocessing visitor is called before the contained declarations are scanned; the postprocessing visitor is called after the contained declarations are scanned.
