    • getPooledConnection

      PooledConnection getPooledConnection() throws SQLException
      Attempts to establish a physical database connection that can be used as a pooled connection.
      Returns:
      a PooledConnection object that is a physical connection to the database that this ConnectionPoolDataSource object represents
      Throws:
      SQLException - if a database access error occurs
      SQLFeatureNotSupportedException - if the JDBC driver does not support this method
      Since:
      1.4

    • getPooledConnection

      PooledConnection getPooledConnection​(String user, String password) throws SQLException
      Attempts to establish a physical database connection that can be used as a pooled connection.
      Parameters:
      user - the database user on whose behalf the connection is being made
      password - the user's password
      Returns:
      a PooledConnection object that is a physical connection to the database that this ConnectionPoolDataSource object represents
      Throws:
      SQLException - if a database access error occurs
      SQLFeatureNotSupportedException - if the JDBC driver does not support this method
      Since:

    • 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.

      Specified by:
      getLogWriter in interface CommonDataSource
      Returns:
      the log writer for this data source or null if logging is disabled
      Throws:
      SQLException - if a database access error occurs
      Since:
      1.4

      CommonDataSource.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.

      Specified by:
      setLogWriter in interface CommonDataSource
      Parameters:
      out - the new log writer; to disable logging, set to null
      Throws:
      SQLException - if a database access error occurs
      Since:
      1.4

    • 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.

      Specified by:
      setLoginTimeout in interface CommonDataSource
      Parameters:
      seconds - the data source login time limit
      Throws:
      SQLException - if a database access error occurs.
      Since:
      1.4

      CommonDataSource.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.
      Specified by:
      getLoginTimeout in interface CommonDataSource
      Returns:
      the data source login time limit
      Throws:
      SQLException - if a database access error occurs.

    • createPooledConnectionBuilder

      default PooledConnectionBuilder createPooledConnectionBuilder() throws SQLException
      Creates a new PooledConnectionBuilder instance
      Implementation Requirements:
      The default implementation will throw a SQLFeatureNotSupportedException.
      Returns:
      The ConnectionBuilder instance that was created
      Throws:
      SQLException - if an error occurs creating the builder
      SQLFeatureNotSupportedException - if the driver does not support sharding
