  • Method Details

    • getLogWriter

      public PrintWriter getLogWriter() throws SQLException

      Retrieves the log writer for this DataSource 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 the java.sql.DriverManager class. When a DataSource object is created, the log writer is initially null; in other words, the default is for logging to be disabled.

      Specified by:
      getLogWriter in interface CommonDataSource
      Specified by:
      getLogWriter in interface DataSource
      Returns:
      the log writer for this data source or null if logging is disabled
      Throws:
      SQLException - if a database access error occurs

    • setLogWriter

      public void setLogWriter(PrintWriter out) throws SQLException

      Sets the log writer for this DataSource object to the given java.io.PrintWriter 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 the java.sql.DriverManager class. When a DataSource object is created the log writer is initially null; in other words, the default is for logging to be disabled.

      Specified by:
      setLogWriter in interface CommonDataSource
      Specified by:
      setLogWriter in interface DataSource
      Parameters:
      out - the new log writer; to disable logging, set to null
      Throws:
      SQLException - if a database access error occurs

    • setLoginTimeout

      public void setLoginTimeout(int seconds) throws SQLException

      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 a DataSource object is created, the login timeout is initially zero.

      Specified by:
      setLoginTimeout in interface CommonDataSource
      Specified by:
      setLoginTimeout in interface DataSource
      Parameters:
      seconds - the data source login time limit
      Throws:
      SQLException - if a database access error occurs.

    • getLoginTimeout

      public int getLoginTimeout() throws SQLException
      Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. A value of zero means that the timeout is the default system timeout if there is one; otherwise, it means that there is no timeout. When a DataSource object is created, the login timeout is initially zero.
      Specified by:
      getLoginTimeout in interface CommonDataSource
      Specified by:
      getLoginTimeout in interface DataSource
      Returns:
      the data source login time limit
      Throws:
      SQLException - if a database access error occurs.

    • getParentLogger

      public Logger getParentLogger() throws SQLFeatureNotSupportedException
      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.
      Specified by:
      getParentLogger in interface CommonDataSource
      Returns:
      the parent Logger for this data source
      Throws:
      SQLFeatureNotSupportedException - if the data source does not use java.util.logging

      Returns:
      a connection to the data source
      Throws:
      SQLException - if a database access error occurs
      SQLTimeoutException - when the driver has determined that the timeout value specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt
