Package frysk.expr Description

This package implements frysk's expression handling.

Overview

Frysk uses the antlr parser generator to generate an expression parser. ExprSymTab.java provides the interface between the antlr generated parser, which is specified in CExprEvaluator.g, CExpr.g, and CTypeEvaluator.g, and the frysk hpd requests.
