- ## Methodendetails

  - ### autoDetectAdapter

    public static Adapter autoDetectAdapter(Connection con) throws InstantiationException, SQLException
    Creates a new instance of the Torque database adapter based on the JDBC meta-data
    Parameter:
      `con` - a database connection
    Gibt zurück:
      An instance of a Torque database adapter, or null if no adapter could be detected.
    Löst aus:
      `InstantiationException` - if the adapter could not be instantiated
      `SQLException` - if there are problems getting the JDBC meta data

  - ### setCapabilities

    public static void setCapabilities(Connection con, Adapter adapter) throws SQLException
    Update static capabilities of the Torque database adapter with actual readings based on the JDBC meta-data
    Parameter:
      `con` - a database connection
      `adapter` - an adapter
    Löst aus:
      `SQLException` - if there are problems getting the JDBC meta data

  - ### create

    public static Adapter create(String key) throws InstantiationException
    Creates a new instance of the Torque database adapter associated with the specified JDBC driver or adapter key.
    Parameter:
      `key` - The fully-qualified name of the JDBC driver or a shorter form adapter key.
    Gibt zurück:
      An instance of a Torque database adapter, or null if no adapter exists for the given key.
    Löst aus:
      `InstantiationException` - throws if the adapter could not be instantiated

  - ### create

    public static Adapter create(String key, String className) throws InstantiationException
    Creates a new instance of the Torque database adapter associated with the specified JDBC driver or adapter key and the class defined.
    Parameter:
      `key` - The fully-qualified name of the JDBC driver or a shorter form adapter key.
      `className` - The fully qualified name of the adapter class
    Gibt zurück:
      An instance of a Torque database adapter.
    Löst aus:
      `InstantiationException` - throws if the adapter could not be instantiated
