15. trait IOList[T <: IOBase] extends IOBase

    

    :: AlpineSdkApi :: A list of IOBase objects.

16. trait IOMetadata extends AnyRef

    

    This can be passed from parent to child operator at design-time.

    This can be passed from parent to child operator at design-time. It is part of the input and output objects of OperatorGUINode#getOperatorStatus. It is used to contain metadata about the IOBase objects that will be passed at runtime.

    e.g. For a dataset: what the TabularSchema will be, what data-source it will be stored on. For a RowModel: what the input and output features will be, what the string identifier will be.
