List of all members.

Detailed Description

An abstract base class for implementing text encodings like UTF-8 or ISO 8859-1.

Subclasses must override the canonicalName(), isA(), characterMap() and convert() methods and need to be thread safe and stateless.

TextEncoding also provides static member functions for managing mappings from encoding names to TextEncoding objects.
