inputFields
Description copied from interface:PreProcessorThe expected input fields- Specified by:
inputFieldsin interfacePreProcessor
-
outputFields
- Specified by:

processin interfacePreProcessor- Parameters:
fields- The fields and their values to process
-
reverseLookup
- Specified by:
reverseLookupin interfacePreProcessor- Returns:
- Reverse lookup map to match resulting features to their original feature name
-
