Synopsis

This class is a specialization of the abstract base class DataConversion . It contains functions to copy data without conversion.

This class exists to make it possible to use a DataConversion object when no conversion is actually needed.

Example

See example in class DataConversion .

Motivation

This class makes it possible to use the conversion framework for operations where a conversion is only a simple copy.

To Do

• Support data type long double.
