Detailed Description

Attribute that gets its value from a user-defined function The updateValue() method for this class retrieves the current value from the function.

Constructor & Destructor Documentation

◆ functAttribute() [1/2]

functAttribute::functAttribute	(	const char *	pName,
		const char *	pDescription,
		const char *	pSource,
		const char *	pParam
	)

Constructor for function attribute.

Parameters

[in]	pName	The name of the attribute to be created; case-insensitive.
[in]	pDescription	The description of the attribute.
[in]	pSource	The symbol name for the function to be called to get the value of the parameter.
[in]	pParam	A string that will be passed to the function, typically to specify what/how to get the value.

◆ functAttribute() [2/2]

functAttribute::functAttribute ( functAttribute & attribute )

Copy constructor for function attribute.

Parameters

[in] attribute The functAttribute to copy from.

◆ ~functAttribute()

functAttribute::~functAttribute ( )

Destructor for driver/plugin attribute.

Member Function Documentation

◆ copy()

functAttribute * functAttribute::copy ( NDAttribute * pOut )

virtual

Copies properties from this to pOut.

Parameters

[in] pOut A pointer to the output attribute If NULL the output attribute will be created using the copy constructor Only the value is copied, all other fields are assumed to already be the same in pOut

Returns: Returns a pointer to the copy

Reimplemented from NDAttribute.

◆ report()

int functAttribute::report	(	FILE *	fp,
		int	details
	)

virtual

Reports on the properties of the functAttribute object; calls base class NDAttribute::report() to report on the parameter value.

Parameters

[in]	fp	File pointer for the report output.
[in]	details	Level of report details desired; currently does nothing in this derived class.

Reimplemented from NDAttribute.

◆ updateValue()

int functAttribute::updateValue ( )

virtual

Updates the current value of this attribute; sets the attribute value to the return value of the specified function.

Reimplemented from NDAttribute.
