  6. def checkSingleVsMultiColumnParams(model: Params, singleColumnParams: Seq[Param[_]], multiColumnParams: Seq[Param[_]]): Unit

    Utility for Param validity checks for Transformers which have both single- and multi-column support.

    Utility for Param validity checks for Transformers which have both single- and multi-column support. This utility assumes that inputCol indicates single-column usage and that inputCols indicates multi-column usage.

    This checks to ensure that exactly one set of Params has been set, and it raises an IllegalArgumentException if not.

    singleColumnParams

    Params which should be set (or have defaults) if inputCol has been set. This does not need to include inputCol.

    multiColumnParams

    Params which should be set (or have defaults) if inputCols has been set. This does not need to include inputCols.
