    • Method Detail

      • getLogWriter

        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.

        Returns:
        the log writer for this data source or null if logging is disabled
        Throws:
        SQLException - if a database access error occurs
        See Also:
        setLogWriter(java.io.PrintWriter)

      • setLogWriter

        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.

        Parameters:
        out - the new log writer; to disable logging, set to null
        Throws:
        SQLException - if a database access error occurs

      • setLoginTimeout

        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.

        Parameters:
        seconds - the data source login time limit
        Throws:
        SQLException - if a database access error occurs.
        See Also:
        getLoginTimeout()

      • getLoginTimeout

        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.
        Returns:
        the data source login time limit
        Throws:
        SQLException - if a database access error occurs.
        See Also:
        setLoginTimeout(int)

      • getParentLogger

        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.
        Returns:
        the parent Logger for this data source
        Throws:
        SQLFeatureNotSupportedException - if the data source does not use java.util.logging

      • createShardingKeyBuilder

        default ShardingKeyBuilder createShardingKeyBuilder​()
                                             throws SQLException
        Creates a new ShardingKeyBuilder instance
        Implementation Requirements:
        The default implementation will throw a SQLFeatureNotSupportedException.
        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
