    • Method Detail

      • 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
