Step 2 - The Parser http://www.ahristov.com/tutoriales/java-compiler/duplicating-parser.html This series focuses on the introducion of a new operator - the # - that performs an already existing functionality. In this article we show how to make the parser recognize the new operator and construct an appopriate AST tree, as well as how to integrate the operator in the existing precedence system. es (c) 2006 Alexander Hristov.
