TranslationDevice Class Reference

This class is intended as a secondary superclass for those Stream classes that are implemented using InterSystems IRIS devices and thus support the use of a Translation Table for character set conversion on input, on output, or both. More...

Detailed Description

This class is intended as a secondary superclass for those Stream classes that are implemented using InterSystems IRIS devices and thus support the use of a Translation Table for character set conversion on input, on output, or both.

It contains a property TranslationTable that names the translation table to be used, if any. It also implements a number of classmethods to support the use of a Translation Table. This class also extends the class ILineStream which facilitates line-by-line Read and Write operations.
