compare two records based on their duplicate scores . the duplicate scores for each record is assume to be pre-computed by computeduplicatescore and stored in the `` ds '' tag . if the scores are equal , we break ties based on mapping quality added to the mate 's mapping quality if paired and mapped , then library/read name . we allow different scoring strategies . we return < 0 if rec1 has a better strategy than rec2 . concode_field_sep PlaceHolder placeHolder concode_field_sep short getSumOfBaseQualities concode_elem_sep short computeDuplicateScore concode_elem_sep short computeDuplicateScore
