Constructor & Destructor Documentation

ParameterEvaluator()

ParameterEvaluator	(	const HString &	rName,
		const HString &	rValue,
		const HString &	rDescription,
		const HString &	rQuantity,
		const HString &	rUnit,
		const HString &	rType,
		void *	pDataPtr = 0,
		ParameterEvaluatorHandler *	pParameterEvalHandler = 0
	)

Constructor.

Parameters

[in]	rName	The desired parameter name, e.g. m
[in]	rValue	The value of the parameter, always a string
[in]	rDescription	The description of the parameter e.g. Mass
[in]	rQuantity	The physical quantity of the parameter e.g. Mass
[in]	rUnit	The physical unit of the parameter e.g. kg
[in]	rType	The type of the parameter e.g. double
[in]	pDataPtr	Only used by Components, system parameters don't use this, default: 0
[in]	pParentParameters	A pointer to the Parameters object that contains the Parameter

evaluate() [1/2]

bool evaluate

(

)

Evaluate the parameter.

Returns

true if success, otherwise false

This function is used by Parameters. The point with run this function is to write the right value to the mData pointer.

See also

evaluate(HString &result)

evaluate() [2/2]

bool evaluate

(

HString &

rResult

)

Evaluate the parameter.

Parameters

[out]

rResult

The result of the evaluation

Returns

true if success, otherwise false

This function is used by Parameters

See also

evaluate()

getDataPtr()

void * getDataPtr

(

)

Returns a pointer directly to the parameter data variable.

Warning

Don't use this function unless YOU REALLY KNOW WHAT YOU ARE DOING

getType()

const HString & getType

(

)

const

Returns the type of the parameter.

Returns

The type of the parameter

setParameterValue()

bool setParameterValue	(	const HString &	rValue,
		ParameterEvaluator **	ppNeedEvaluation = 0,
		bool	force = false
	)

Set the parameter value for an existing parameter.

Parameters

[in]	rValue	The new value for the parameter
[out]	ppNeedEvaluation	Tell if the parameter needs evaluation, e.g. is a system parameter or an expression

Returns

true if success, otherwise false

This function is used by Parameters
