- All Implemented Interfaces:
Token
public class ClassicToken extends Object implements Token
A Token object like we'd use in ANTLR 2.x; has an actual string created and associated with this object. These objects are needed for imaginary tree nodes that have payload objects. We need to create a Token object that has a string; the tree node will point at this token. CommonToken has indexes into a char stream and hence cannot be used to introduce new strings.
