NAME

       QSqlDriverPlugin - Abstract base for custom QSqlDriver plugins

SYNOPSIS

       #include <qsqldriverplugin.h>

   Public Members
       QSqlDriverPlugin ()
       ~QSqlDriverPlugin ()
       virtual QStringList keys () const = 0
       virtual QSqlDriver * create ( const QString & key ) = 0

DESCRIPTION

       The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins.

       The SQL driver plugin is a simple plugin interface that makes it easy to create your own SQL driver plugins that can be loaded dynamically
       by Qt.

       Writing a SQL plugin is achieved by subclassing this base class, reimplementing the pure virtual functions keys() and create(), and
       exporting the class with the Q_EXPORT_PLUGIN macro. See the SQL plugins that come with Qt for example implementations (in the
       plugins/src/sqldrivers subdirectory of the source distribution). Read the plugins documentation for more information on plugins.

       See also Plugins.

MEMBER FUNCTION DOCUMENTATION

QSqlDriverPlugin::QSqlDriverPlugin ()
       Constructs a SQL driver plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QSqlDriverPlugin::~QSqlDriverPlugin ()
       Destroys the SQL driver plugin.

       You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.

QSqlDriver * QSqlDriverPlugin::create ( const QString & key ) [pure virtual]
       Creates and returns a QSqlDriver object for the driver key key. The driver key is usually the class name of the required driver.

       See also keys().

QStringList QSqlDriverPlugin::keys () const [pure virtual]
       Returns the list of drivers (keys) this plugin supports.

       These keys are usually the class names of the custom drivers that are implemented in the plugin.

       See also create().
