#include <IMP/ScoreAccumulator.h>
Inheritance diagram for IMP::ScoreAccumulator:Class for adding up scores during ScoringFunction evaluation.
This provides a place to accumulate scores from Restraint evaluation. A new ScoreAccumulator is created for each Restraint evaluation context (eg each Restraint::add_score_and_derivatives() call). As a result, the ScoreAccumulator can automatically handle restraint and derivative weights, keeping track of maximum scores and other needed bookkeeping.

| IMP::ScoreAccumulator::ScoreAccumulator | ( | ScoreAccumulator | o, |
| const Restraint * | r | ||

Compose outer accumulator with one for this restraint.
| IMP::ScoreAccumulator::ScoreAccumulator | ( | ScoreAccumulator | o, |
| double | weight, | ||
| double | local_max | ||
| ) |
Compose outer accumulator with one for this restraint.
Definition at line 71 of file ScoreAccumulator.h.
| void IMP::ScoreAccumulator::add_score | ( | double | score | ) |
Add to the total score. It will be weighted appropriately internally.
Definition at line 79 of file ScoreAccumulator.h.
| bool IMP::ScoreAccumulator::get_abort_evaluation | ( | ) | const |
Return if the score already exceeds the maximum.
Expensive restraints can check this during evaluation to determine if another restraint has aborted evaluation.
Definition at line 94 of file ScoreAccumulator.h.
| bool IMP::ScoreAccumulator::get_is_evaluate_if_below | ( | ) | const |
Return true if the current evaluation being done is one where scores are only considered if they are below some threshold (get_maximum()).
Definition at line 112 of file ScoreAccumulator.h.
| bool IMP::ScoreAccumulator::get_is_evaluate_if_good | ( | ) | const |
Return true if the current evaluation should abort if any restraint is above its maximum allowed good score. Restraints that take advantage of this in evaluation should simply consult get_maximum() as that will take into account both their maximum and that on any RestraintSets that contain them and are being evaluated.
Definition at line 120 of file ScoreAccumulator.h.
| double IMP::ScoreAccumulator::get_maximum | ( | ) | const |
The maximum allowed score for the Restraint::do_add_score_and_derivatives() call.
