\class QTextCodecPlugin
\brief The QTextCodecPlugin class provides an abstract base for custom QTextCodec plugins.
\reentrant
\ingroup plugins
The text codec plugin is a simple plugin interface that makes it
easy to create custom text codecs that can be loaded dynamically
into applications.
Writing a text codec plugin is achieved by subclassing this base
class, reimplementing the pure virtual functions names(),
aliases(), createForName(), mibEnums() and createForMib(), and
exporting the class with the Q_EXPORT_PLUGIN2() macro. See \l{How
to Create Qt Plugins} for details.
See the \l{http://www.iana.org/assignments/character-sets}{IANA
character-sets encoding file} for more information on mime
names and mib enums.
*/
/*!
\fn QStringList QTextCodecPlugin::names() const
Returns the list of MIME names supported by this plugin.
If a codec has several names, the extra names are returned by aliases().
\sa createForName(), aliases()
*/
/*!
\fn QList<QByteArray> QTextCodecPlugin::aliases() const
Returns the list of aliases supported by this plugin.
*/
/*!
\fn QTextCodec *QTextCodecPlugin::createForName(const QByteArray &name)
Creates a QTextCodec object for the codec called \a name. The \a name
must come from the list of encodings returned by names(). Encoding
names are case sensitive.
Example:
\snippet doc/src/snippets/code/src_corelib_codecs_qtextcodecplugin.cpp 0
\sa names()
*/
/*!
\fn QList<int> QTextCodecPlugin::mibEnums() const
Returns the list of mib enums supported by this plugin.
\sa createForMib()
*/
/*!
\fn QTextCodec *QTextCodecPlugin::createForMib(int mib);
Creates a QTextCodec object for the mib enum \a mib.
See \l{http://www.iana.org/assignments/character-sets}{the
IANA character-sets encoding file} for more information.
\sa mibEnums()
*/

Constructs a text codec plugin with the given \a parent. This is
invoked automatically by the Q_EXPORT_PLUGIN2() macro.

Destroys the text codec plugin.
You never have to call this explicitly. Qt destroys a plugin
