Detailed Description

This class wraps the MySQL driver class, providing easier change for the future Also, for performance, this class may one day become an ObjectPool of connections for greater efficiency

SraData::DbConnectionFactory::DbConnectionFactory	(	const std::string &	dbName,
		const std::string &	login,
		const std::string &	password,
		const std::string &	schema
	)

Sets the database information for this object, sets this instance as the Singleton, and initializes the MySQL driver

Definition at line 26 of file DbConnectionFactory.cpp.

References _driver, get_driver_instance(), ObjectPool< sql::Connection >::setDeleteAllInstances(), and Singleton< DbConnectionFactory >::SetSingleton().

            _schema(schema)
    {
        //create an instance of the driver on creation of the factory
        //this will be used to create connections in the future
        _driver = get_driver_instance();

        //set singleton up for this class
        SetSingleton(this);

        //when this factory dies, all of its children must die (so sad)
        setDeleteAllInstances(true);
