class XxxArithExpression : public XxxValueExpression

Simple arithmetic expressions

Inheritance:

Public Methods

virtual XxxBool	Match (const XxxExpression* OtherExpr, char *Env = NULL) Checks to see if the expression matches another expression
virtual XxxBool	Match (const XxxExpression* RuleExpr, XxxBindingEnv *BindEnv) Checks if the expression matches another rule input expression If match is successful, return true, and assign BindTerm array inside XxxBindingEnv class
virtual XxxExpression*	Replicate () Provides a convenient way to copy arbitrary expressions
	XxxArithExpression (const XxxArithExpression &src) Copy constructor.
