sparta::statistics::expression Namespace Reference

Namespace containing methods for parsing, building, and evaluating statistical expressions in sparta. More...

Namespaces
namespace	grammar
	Statistical Expression Grammar.

Classes
struct	BinaryFunction
	Represents a Binary function node. More...
struct	Constant
class	Expression
	Expression container/builder. Contains a single ExpressionNode representing the root of an expression tree. This is the object on which the parser operates to build an expression incrementally through basic operators. More...
class	ExpressionNode
	Abstract interface class for an item in an expression. Subclasses can contain other ExpressionNodes. More...
class	ExpressionParser
	Class for parsing statistical expressions based on a specific TreeNode context. More...
struct	Operation
	Operation Node (e.g. +,-,*,/) More...
struct	ReferenceVariable
	Expression node for a reference to a double. Anything that cannot actually vary can be handled as a constant through Expression. If it can vary, however, it should be handled through this or SimVariable (for functions) More...
struct	SimVariable
	Expression node for a simulation variable. Anything that cannot actually vary within a simulation can be handled as a Constant. If it can vary, however, it should be handled through this. More...
struct	StatVariable
struct	TernaryFunction
	Represents a Ternary function node. More...
struct	UnaryFunction
	Represents a Unary function node. More...

Functions
