/*!
 * \class KPluginFactory
 * \inmodule KCoreAddons
 *
 * \brief KPluginFactory provides a convenient way to provide factory-style plugins.
 *
 * Qt plugins provide a singleton object, but a common pattern is for plugins
 * to generate as many objects of a particular type as the application requires.
 * By using KPluginFactory, you can avoid implementing the factory pattern
 * yourself.
 *
 * KPluginFactory also allows plugins to provide multiple different object
 * types, indexed by keywords.
 *
 * The objects created by KPluginFactory must inherit QObject, and must have a
 * standard constructor pattern:
 * \list
 * \li if the object is a KPart::Part, it must be of the form
 * \code
 * T(QWidget *parentWidget, QObject *parent, const QVariantList &args)
 * \endcode
 * or
 * \code
 * T(QWidget *parentWidget, QObject *parent, const KPluginMetaData &metaData, const QVariantList &args)
 * \endcode
 * \li if it is a QWidget, it must be of the form
 * \code
 * T(QWidget *parent, const QVariantList &args)
 * \endcode
 * or
 * \code
 * T(QWidget *parent, const KPluginMetaData &metaData, const QVariantList &args)
 * \endcode
 * \li otherwise it must be of the form
 * \code
 * T(QObject *parent, const QVariantList &args)
 * \endcode
 * or
 * \code
 * T(QObject *parent, const KPluginMetaData &metaData, const QVariantList &args)
 * \endcode
 * \endlist
 * You should typically use either K_PLUGIN_CLASS() or
 * K_PLUGIN_CLASS_WITH_JSON() in your plugin code to generate a factory.
 * The typical pattern is:
 *
 * \code
 * #include <KPluginFactory>
 * #include <plugininterface.h>
 *
 * class MyPlugin : public PluginInterface
 * {
 * public:
 *     MyPlugin(QObject *parent, const QVariantList &args)
 *         : PluginInterface(parent)
 *     {}
 * };
 *
 * K_PLUGIN_CLASS(MyPlugin)
 * #include <myplugin.moc>
 * \endcode
 *
 * If you want to write a custom KPluginFactory not using the standard macro(s)
 * you can reimplement the
 * create(const char *iface, QWidget *parentWidget, QObject *parent, const QVariantList &args)
 * method.
 *
 * Example:
 * \code
 * class SomeScriptLanguageFactory : public KPluginFactory
 * {
 *     Q_OBJECT
 * public:
 *     SomeScriptLanguageFactory()
 *     {}
 *
 * protected:
 *     virtual QObject *create(const char *iface, QWidget *parentWidget, QObject *parent, const QVariantList &args)
 *     {
 *         // Create an identifier based on the iface and given pluginId
 *         const QString identifier = QLatin1String(iface) + QLatin1Char('_') + metaData().pluginId();
 *         // load scripting language module from the information in identifier and return it:
 *         return object;
 *     }
 * };
 * \endcode
 *
 * To load the KPluginFactory from an installed plugin you can use loadFactory() and for
 * directly creating a plugin instance from it instantiatePlugin()
 *
