Method Detail

• getLogWriter

  PrintWriter getLogWriter()                  throwsSQLException

  Retrieves the log writer for thisDataSource object.

  The log writer is a character output stream to which all logging and tracing messages for this data source will be printed. This includes messages printed by the methods of this object, messages printed by methods of other objects manufactured by this object, and so on. Messages printed to a data source specific log writer are not printed to the log writer associated with thejava.sql.DriverManager class. When aDataSource object is created, the log writer is initially null; in other words, the default is for logging to be disabled.

  Returns:

  the log writer for this data source or null if logging is disabled

  Throws:

  SQLException - if a database access error occurs

  setLogWriter(java.io.PrintWriter)

• setLogWriter

  void setLogWriter(PrintWriter out)           throwsSQLException

  Sets the log writer for thisDataSource object to the givenjava.io.PrintWriter object.

  Parameters:

  out - the new log writer; to disable logging, set to null

• setLoginTimeout

  void setLoginTimeout(int seconds)              throwsSQLException

  Sets the maximum time in seconds that this data source will wait while attempting to connect to a database. A value of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies that there is no timeout. When aDataSource object is created, the login timeout is initially zero.

  Parameters:

  seconds - the data source login time limit

  Throws:

  SQLException - if a database access error occurs.

• getParentLogger

  Logger getParentLogger()                throwsSQLFeatureNotSupportedException

  Return the parent Logger of all the Loggers used by this data source. This should be the Logger farthest from the root Logger that is still an ancestor of all of the Loggers used by this data source. Configuring this Logger will affect all of the log messages generated by the data source. In the worst case, this may be the root Logger.

  Returns:

  the parent Logger for this data source

  Throws:

  SQLFeatureNotSupportedException - if the data source does not usejava.util.logging

  Implementation Requirements:

  The default implementation will throw aSQLFeatureNotSupportedException.

  Returns:

  The ShardingKeyBuilder instance that was created

  Throws:

  SQLException - if an error occurs creating the builder

  SQLFeatureNotSupportedException - if the driver does not support this method
