/**
 * @class TAO_Codeset_Translator_Factory
 *
 * @brief Abstract base class for factories providing codeset translators
 *
 * The codeset translator factory is a loadable service object. It is used to
 * supply the actual translator used in converting between two codesets. The
 * intent of using a factory is to avoid requiring codeset translators to be
 * multiply inherited both from the translator base class and the service
 * object base. The translator factory is also responsible for assigning
 * translators to CDR streams. Since there is no common base class between
 * input and output CDRs, the assingment code must be duplicated.
