Interface ParameterizedFeatureExtractor<SOURCE_DATA,PARAM>

All Superinterfaces:

FeatureExtractor<SOURCE_DATA>

public interface ParameterizedFeatureExtractor<SOURCE_DATA,PARAM>
extends FeatureExtractor<SOURCE_DATA>

This extension of the FeatureExtractor rely on extra parameters to extract features. The expectation is that the Feathr engine will call `init` when constructing an instance of this Extractor and implementation of this interface is responsible for maintaining any state for the parameters as needed.
