Type Parameters:

OUT - The output type of an operator that will be constructed using StreamOperatorParameters.

@Experimental
public class StreamOperatorParameters<OUT>
extends Object

Helper class to construct AbstractStreamOperatorV2. Wraps couple of internal parameters to simplify for users construction of classes extending AbstractStreamOperatorV2 and to allow for backward compatible changes in the AbstractStreamOperatorV2's constructor.
