public class Token
extends java.lang.Object

Tokens are the basic units of the scanning and parsing process. Tokens are created by the syntax scanner implementations in compliance with a given syntax for the source language. lists of tokens representing statements that are written in the source language are passed to the handlers, which attempt to construct a parse-tree for the statement. If successful, the parser takes the generated parse-tree and adds it to the program model.
