Detailed Description

Attribute that gets its value from an asynNDArrayDriver driver parameter.

The updateValue() method for this class retrieves the current value of the driver parameter.

Constructor & Destructor Documentation

paramAttribute() [1/2]

paramAttribute::paramAttribute	(	const char *	pName,
		const char *	pDescription,
		const char *	pSource,
		int	addr,
		class asynNDArrayDriver *	pDriver,
		const char *	dataType
	)

Constructor for driver/plugin attribute.

Parameters

[in]	pName	The name of the attribute to be created; case-insensitive.
[in]	pDescription	The description of the attribute.
[in]	pSource	The DRV_INFO string used to identify the parameter in the asynPortDriver.
[in]	addr	The asyn addr (address) for this parameter.
[in]	pDriver	The driver or plugin object from which to obtain the parameter.
[in]	dataType	The data type for this parameter. Must be "INT", "DOUBLE", or "STRING" (case-insensitive).

paramAttribute() [2/2]

paramAttribute::paramAttribute

(

paramAttribute &

attribute

)

Copy constructor for driver/plugin attribute.

Parameters

[in]

attribute

A paramAttribute to copy from

~paramAttribute()

paramAttribute::~paramAttribute

(

)

Destructor for driver/plugin attribute.

Member Function Documentation

copy()

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

virtual

Reports on the properties of the paramAttribute 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 paramAttribute::updateValue ( )

virtual

Updates the current value of this attribute; sets the attribute value to the current value of the driver/plugin parameter in the parameter library.

Reimplemented from NDAttribute.
