public interface FIDReader
FeatureReadercustomized for FeatureID handling. An experimental method for doing FIDs. I'd like to see it and AttributeReader extend a similar base. Perhaps BaseReader or something? And perhaps have FeatureReader
extend it too? This reader just returns an incrementing index. May be sufficient for files, representing rows in a file. For jdbc datasources another fid reader should be used. We could have FIDReader implement AttributeReader, but it doesn't seem to make sense, as the getAttributeType doesn't make much sense, as our featureID is just a string. Or we could consider having a special FID attribute in our hierarchy.
