Detailed Description

Derived from Entity, used for storing pointers to math functions.

This class has pointer to functions that are standard math.h functions. These are called from the MathExpression during parsing. Several types are posible of these class.

Note

Example:

EntityType::OperatorInIntOutInt is a function of the type int function(int a_value)

Constructor & Destructor Documentation

Operator::Operator	(	const string &	a_name,
		EntityType	a_type = EntityType::Operator,
		OperatorPrecedence	a_precedence = OperatorPrecedence::Function,
		double(*)(const double)	a_ddOperator = nullptr,
		double(*)(const double, const double)	a_dddOperator = nullptr,
		double(*)(const double, const int)	a_ddiOperator = nullptr
	)

Constructor, with constructor list only.

Parameters

a_name	Name key of the Operator, part of the Entity parent class
a_type	Type of the Operator, part of the Entity parent class
a_precedence	The OperatorPrecedence

Member Function Documentation

double Operator::dddOperator	(	double	a_arg1,
		double	a_arg2
	)		const

Overload of the function call.

Parameters

a_arg1	First argument
a_arg2	Second argument

Returns

double Return value from function(a_arg1, a_arg2)

double Operator::ddOperator

(

double

a_arg1

)

const

Overload of the function call.

Parameters

a_arg1

First argument

Returns

double Return value from function(a_arg1)

uint16_t Operator::precedence

(

)

const

Return the operator precedence as unsigned int.

We return the unsigned int in order to be able to compare two precedences.

Returns

uint16_t The cast of the OperatorPrecedence enum
