      • getResourceIncrementally

        ServerStream getResourceIncrementally​(SessionToken session,
                                      ResourceDescriptor resourceDescriptor)
        The same as getResource(SessionToken, ResourceDescriptor) but with incremental retrieval of the resource.
        Parameters:
        session - The session which is used to check for access rights on this method.
