Method Detail

score

double score(IndexNode ref,
             IndexNode query,
             double origScore)

Description copied from interface: ScoreDT

This method re-scores a given reference query node pair. By default this simply returns the original score that was given and does no computation. If the given original score does not look valid (is less than zero), the score will be re-computed. Some algorithms may choose to implement this method when pruning is best done after initial depth-first traversals have already been completed of other branches.

Double.POSITIVE_INFINITY if the node should be pruned.
