Prerequisite

• AttributeValue
• AttributeValuePoi
• AttributeValueTol

Etymology

"AttributeValuePoiTol" is a contraction of "Attribute Value", "Pointer" and "Tolerance", and stores an Attribute by aliasing it with a pointer and associating it with some tolerance.

Synopsis

An AttributeValuePoiTol combines the aliasing (via a pointer) provided by the AttributeValuePoi class, and the tolerance provided by the AttributeValueTol class. See these classes for examples.

Motivation

The motivation for this class is to be able to provide in-built tolerance and aliasing for AttributeValues.

template<class T>

virtual AttributeValueBase* casa::AttributeValuePoiTol< T >::clone

(

)

const [virtual]

Return a new copy of the AttributeValuePoiTol (virtual constructor).

Reimplemented from casa::AttributeValueTol< T >.

template<class T>

virtual DataType casa::AttributeValuePoiTol< T >::getPointerType

(

)

const [virtual]

Get the DataType of the aliased variable.

template<class T>

const AttributeValuePoiTol<T>& casa::AttributeValuePoiTol< T >::myCast

(

const AttributeValueBase &

other

)

const [private]

Cast from Base class.

Reimplemented from casa::AttributeValue< T >.

template<class T>

virtual void casa::AttributeValuePoiTol< T >::operator+=

(

const AttributeValueBase &

other

)

[virtual]

Add other to *this.

Needs to over-ride base class definition because the pointers need to be dereferenced prior to addition.

Reimplemented from casa::AttributeValue< T >.

template<class T>

const AttributeValuePoiTol<T>& casa::AttributeValuePoiTol< T >::operator=

(

const AttributeValuePoiTol< T > &

other

)

Assignment operator.

template<class T>

virtual void casa::AttributeValuePoiTol< T >::setValue

(

const T &

value

)

[virtual]

Change the value of the AttributeValue.

Reimplemented from casa::AttributeValue< T >.

template<class T>

virtual void casa::AttributeValuePoiTol< T >::setValue

(

const Vector< T > &

value

)

[virtual]

Reimplemented from casa::AttributeValue< T >.

template<class T>

void casa::AttributeValuePoiTol< T >::updatePointerValue

(

)

const [private]

Update the variable that is aliased to the AttributeValuePoiTol.

Member Data Documentation

template<class T>

DataType casa::AttributeValuePoiTol< T >::itsPointerType [private]

The pointer DataType.

Definition at line 129 of file AttValPoiTol.h.

template<class T>

T* casa::AttributeValuePoiTol< T >::itsScalarPointerPtr [private]

Definition at line 125 of file AttValPoiTol.h.

template<class T>

Vector<T>* casa::AttributeValuePoiTol< T >::itsVectorPointerPtr [private]

Pointer to the aliased variable.

Only one is ever active depending upon how the object was constructed. The memory allocated to these pointers does not belong to this object.
