          public DLNAHeader()

  - ### Method Detail

    - #### newInstance

          public static DLNAHeader newInstance(DLNAHeader.Type type,
                               String headerValue)

      Create a new instance of a `DLNAHeader` subtype that matches the given type and value.

      This method iterates through all potential header subtype classes as declared in `DLNAHeader.Type`. It creates a new instance of the subtype class and calls its `UpnpHeader.setString(String)` method. If no `InvalidHeaderException` is thrown, the subtype instance is returned.

      Parameters:
        `type` - The type (or name) of the header.
        `headerValue` - The value of the header.
      Returns:
        The best matching header subtype instance, or `null` if no subtype can be found.
