Interface FeatureValueTypeAdaptor<T>

Type Parameters:
T - the other, alternative FeatureValue representation
public interface FeatureValueTypeAdaptor<T>
A converter that knows how to convert back and forth between Feathr's FeatureValue and some other representation. Implementations' "to" and "from" methods are expected to be inverses of each other, such that toFeathrFeatureValue(fromFeathrFeatureValue(x)) = x and fromFeathrFeatureValue(toFeathrFeatureValue(x)) = x, for any instance 'x' of FeatureValue. NOTE: This class is intended for advanced users only, and specifically as a "migration aid" for migrating from some previous versions of Feathr whose FeatureValue representations had a different class name, while preserving compatibility with feature definitions written against those older versions of Feathr.

  • Method Details

    • toFeathrFeatureValue

      FeatureValue toFeathrFeatureValue(T other)
      Convert from the "other" representation into Feathr FeatureValue. It is expected to be the inverse of fromFeathrFeatureValue(FeatureValue)
      Parameters:
      other - the feature value in the "other" representation
      Returns:
      the feature value represented as a Feathr FeatureValue

    • fromFeathrFeatureValue

      T fromFeathrFeatureValue(FeatureValue featureValue)
      Convert from Feathr FeatureValue into the "other" representation. It is expected to be the inverse of toFeathrFeatureValue(Object)
      Parameters:
      featureValue - the feature value represented as a Feathr FeatureValue
      Returns:
      the feature value in the "other" representation
