net.percederberg.grammatica.parser.Analyzer

A parse tree analyzer. This class provides callback methods that may be used either during parsing, or for a parse tree traversal. This class should be subclassed to provide adequate handling of the parse tree nodes. The general contract for the analyzer class does not guarantee a strict call order for the callback methods. Depending on the type of parser, the enter() and exit() methods for production nodes can be called either in a top-down or a bottom-up fashion. The only guarantee provided by this API, is that the calls for any given node will always be in the order enter(), child(), and exit(). If various child() calls are made, they will be made from left to right as child nodes are added (to the right). @author Per Cederberg, @version 1.5
