PLMD::lepton Namespace Reference

Classes
class	AsmJitRuntimePtr
class	CompiledExpression
	A CompiledExpression is a highly optimized representation of an expression for cases when you want to evaluate it many times as quickly as possible. More...
class	CustomFunction
	This class is the interface for defining your own function that may be included in expressions. More...
class	Exception
	This class is used for all exceptions thrown by lepton. More...
class	ExpressionProgram
	An ExpressionProgram is a linear sequence of Operations for evaluating an expression. More...
class	ExpressionTreeNode
	This class represents a node in the abstract syntax tree representation of an expression. More...
class	Operation
	An Operation represents a single step in the evaluation of an expression, such as a function, an operator, or a constant value. More...
class	ParsedExpression
	This class represents the result of parsing an expression. More...
class	Parser
	This class provides the main interface for parsing expressions. More...
class	ParseToken
