    • getFactory

      public static ClientJDBCObjectFactory getFactory()
      This method returns an Implementation of ClientJDBCObjectFactory depending on VM under use Currently it returns either ClientJDBCObjectFactoryImpl (or) ClientJDBCObjectFactoryImpl42

    • createDefaultFactoryImpl

      private static ClientJDBCObjectFactory createDefaultFactoryImpl()
      Returns an instance of the ClientJDBCObjectFactoryImpl class

    • createJDBC40FactoryImpl

      private static ClientJDBCObjectFactory createJDBC40FactoryImpl()
      Returns an instance of the ClientJDBCObjectFactoryImpl40 class If a ClassNotFoundException occurs then it returns an instance of ClientJDBCObjectFactoryImpl If a future version of JDBC comes then a similar method would be added say createJDBCXXFactoryImpl in which if the class is not found then it would return the lower version thus having a sort of cascading effect until it gets a valid instance

    • createJDBC42FactoryImpl

      private static ClientJDBCObjectFactory createJDBC42FactoryImpl()
      Returns an instance of the ClientJDBCObjectFactoryImpl42 class If a ClassNotFoundException occurs then it returns an instance of the most refined ClientJDBCObjectFactoryImpl possible If a future version of JDBC comes then a similar method would be added say createJDBCXXFactoryImpl in which if the class is not found then it would return the lower version thus having a sort of cascading effect until it gets a valid instance
