Class Summary

CExprEvaluator
CExprLexer
CExprParser
CTypeEvaluator
DetailedAST	An AST that also retains the location of its token.
Expression	An expression (well actually the expression tree).
ExpressionFactory	Create expressions and related stuff.
ExprSearchEngine	This class adapts ObjectDeclarationSearchEngine so that it is usable by ExprSymTab.
FQIdentifier
FQIdentParser	Funky HPD #-syntax doesn't map very well to LL-k type parser (for constant 'k').
FQIdentPatternAll	Pattern for part of the FQ identifier that is missing.
FQIdentPatternExact	Pattern for exactly specified part of FQ identifier.
FQIdentPatternGlob	Pattern for part of FQ identifier specified by a glob.
FQIdentToken
ScratchSymTab
TestArithmetics	Scratch is for the case where there isn't any symbols, basic ops should still work.
TestbedSymTab
TestCompletion	Create expressions and related stuff.

Exception Summary

CompletionException	An incomplete blah.
FQIdentParser.ExtraGarbageException

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.
