public int[] extractedFieldIndexes()
Context
The indexes are relative to their original position in the input.
For example, if the input has the fields "A, B, C, D", and the selected fields are "A, D", then the extracted field indexes will return [0, 3]
If no fields were selected, then this method will return null. This means all fields are being parsed.
