Classes
class	AbsoluteValueExpression
class	AddExpression
class	AndExpression
class	ArithmeticASTAndClause
class	ArithmeticASTExpression
class	ArithmeticASTFactor
class	ArithmeticASTFunction
class	ArithmeticASTNode
	Base class for Abstract Syntax Tree (AST) for the simple Arithmetic language defined here. More...
class	ArithmeticASTOrClause
class	ArithmeticASTRestAndClause
class	ArithmeticASTRestExpression
class	ArithmeticASTRestOrClause
class	ArithmeticASTRestTerm
class	ArithmeticASTTerm
class	ArithmeticASTValue
	either a variable or a literal. More...
class	ArithmeticScanner
class	ASTPrinter
	Traverse the AST and print it to standard out. More...
class	ASTVisitor
	Double-dispatch visitor pattern for abstract syntax tree. More...
class	BinaryExpression
class	BooleanExpressionCreator
class	BooleanExpressionScanner
class	DivideExpression
class	EqualsExpression
class	Expression
	Pure virtual base class to define arbitrary expressions for scripting arithmetic operations (e.g. addition and multipliction). More...
class	ExpressionCreator
	Class to traverse the abstract syntax tree produced by the parsing of a properly-formed string in the Arithmetic expression language. Produces an Expression tree capable of performing arithmetic. Connects the "variable" nodes in this tree to the owning WrapperOptEMultifunc so that their values can be retrieved during expression evaluation inside the WrapperOptEMultifunc functor. More...

class	LTE_Expression
	Less Than or Equal To. More...
class	MaxExpression
class	MetaMaxExpression
	Evaluates ee1 when e1 is larger than e2; evaluates ee2 otherwise. More...
class	MetaMinExpression
	Evaluates ee1 when e1 is less than e2; evaluates ee2 otherwise. More...
class	MinExpression
class	MultiplyExpression
class	NaryExpression
