ParameterObject(subjectPlant: BaseAssertionPlant<TSubject, *>, extractionNotSuccessful: Translatable, warningCannotEvaluate: Translatable, canBeExtracted: (TSubject) -> Boolean, featureExtraction: (TSubject) -> T)
A parameter object which contains all necessary information to extract a feature -- however, not to create assertions.
subjectPlant - The AssertionPlant which contains the subject from which the subject is extracted.
extractionNotSuccessful - Used as AssertionGroup.representation in case canBeExtracted
evaluates to false.
warningCannotEvaluate - The Translatable used to explain why the extraction could not be carried out.
canBeExtracted - Indicates whether it is safe to extract the feature or not (e.g. Map.containsKey as
counter part to Map.get)
featureExtraction - The feature extraction as such (e.g. Map.get, List.get etc.)
