* \brief qx::IxRepository : common interface for all repositories to provide access to database by introspection using QObject class or qx::IxCollection class
*
* There is a type verification at runtime using <i>dynamic_cast</i> function.
* For example, if you are working with a class named <i>MyType</i>, you can call all methods of <i>qx::IxRepository</i> interface using :
* - <i>MyType *</i> for a single object, if <i>MyType</i> inherits from <i>QObject</i> ;
* - <i>qx::QxCollection< Key, QSharedPointer<MyType> > *</i> for a list of objects, where <i>Key</i> is the primary key type defined for <i>MyType</i> class (<i>long</i> by default).
*
* Note : if a bad type is detected at runtime, an exception of type <i>qx::dao::sql_error</i> is thrown.
