    Parameters
    ----------
    connections: `PipelineTaskConnections`
        An instance of a `PipelineTaskConnections` object that will be iterated
        over.
    connectionType: `str`
        The type of connections to iterate over, valid values are inputs,
        outputs, prerequisiteInputs, initInputs, initOutputs.

    Yields
