JExpr - a parser for a very small subset of Java. It was created to help me understand what would be necessary to develop a full compiler starting from a JavaCC-generated parser - in effect to answer the FAQ "TODO".

Only a very small subset of Java can be compiled - see expr.txt as an example.

This system consists of the following components:

• A JavaCC parser, JExpr.jj - see JExpr
• A set of Abstract Syntax Tree classes.
• A Contextual (semantic) Analsys visitor.
• An Operator type resolution class used by the Contextual Visitor.
