-/**
- * A visitor for declarations that scans declarations contained within
- * the given declaration in source code order. 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.
- *
- * @deprecated All components of this API have been superseded by the
- * standardized annotation processing API. The replacement for the
- * functionality of this class is {@link
- * javax.lang.model.util.SimpleElementVisitor6}.
