    - #### AbstractDriverBasedDataSource

          public AbstractDriverBasedDataSource()

  - ### Method Detail

    - #### setUrl

          public void setUrl(String url)

      Set the JDBC URL to use for connecting through the Driver.
      See Also:
        `Driver.connect(String, java.util.Properties)`

    - #### getUrl

          public String getUrl()

      Return the JDBC URL to use for connecting through the Driver.

    - #### setUsername

          public void setUsername(String username)

      Set the JDBC username to use for connecting through the Driver.
      See Also:
        `Driver.connect(String, java.util.Properties)`

    - #### getUsername

          public String getUsername()

      Return the JDBC username to use for connecting through the Driver.

    - #### setPassword

          public void setPassword(String password)

      Set the JDBC password to use for connecting through the Driver.
      See Also:
        `Driver.connect(String, java.util.Properties)`

    - #### getPassword

          public String getPassword()

      Return the JDBC password to use for connecting through the Driver.

    - #### setConnectionProperties

          public void setConnectionProperties(Properties connectionProperties)

      Specify arbitrary connection properties as key/value pairs, to be passed to the Driver.

      Can also contain "user" and "password" properties. However, any "username" and "password" bean properties specified on this DataSource will override the corresponding connection properties.

      See Also:
        `Driver.connect(String, java.util.Properties)`

    - #### getConnectionProperties

          public Properties getConnectionProperties()

      Return the connection properties to be passed to the Driver, if any.

    - #### getConnection

          public Connection getConnection()
                                   throws SQLException

      This implementation delegates to `getConnectionFromDriver`, using the default username and password of this DataSource.
      Throws:
        `SQLException`
      See Also:
        `getConnectionFromDriver(String, String)`, `setUsername(java.lang.String)`, `setPassword(java.lang.String)`

    - #### getConnection

          public Connection getConnection(String username,
                                          String password)
                                   throws SQLException

      This implementation delegates to `getConnectionFromDriver`, using the given username and password.
      Throws:
        `SQLException`
      See Also:
        `getConnectionFromDriver(String, String)`

    - #### getConnectionFromDriver

          protected Connection getConnectionFromDriver(String username,
                                                       String password)
                                                throws SQLException

      Build properties for the Driver, including the given username and password (if any), and obtain a corresponding Connection.
      Parameters:
        `username` - the name of the user
        `password` - the password to use
      Returns:
        the obtained Connection
      Throws:
        `SQLException` - in case of failure
      See Also:
        `Driver.connect(String, java.util.Properties)`

    - #### getConnectionFromDriver

          protected abstract Connection getConnectionFromDriver(Properties props)
                                                         throws SQLException

      Obtain a Connection using the given properties.

      Template method to be implemented by subclasses.

      Parameters:
        `props` - the merged connection properties
      Returns:
        the obtained Connection
      Throws:
