  • Method Details

    • setSystemId

      void setSystemId​(String systemId)
      Set the system identifier for this Source.

      The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.

      Parameters:
      systemId - The system identifier as a URL string.

    • getSystemId

      String getSystemId()
      Get the system identifier that was set with setSystemId.
      Returns:
      The system identifier that was set with setSystemId, or null if setSystemId was not called.

    • isEmpty

      default boolean isEmpty()
      Indicates whether the Source object is empty. Empty means that there is no input available from this Source.
      Implementation Requirements:
      The default implementation of this method throws UnsupportedOperationException.
      Returns:
      true if the Source object is empty, false otherwise
