Detailed Description

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.

Constructor & Destructor Documentation

IMP::kernel::ScoreAccumulator::ScoreAccumulator

(

)

For swig, makes invalid (not null) state.

Definition at line 67 of file kernel/ScoreAccumulator.h.

IMP::kernel::ScoreAccumulator::ScoreAccumulator	(	ScoreAccumulator	o,
		const Restraint *	r
	)

Compose outer accumulator with one for this restraint.

IMP::kernel::ScoreAccumulator::ScoreAccumulator	(	ScoreAccumulator	o,
		double	weight,
		double	local_max
	)

Compose outer accumulator with one for this restraint.

Member Function Documentation

void IMP::kernel::ScoreAccumulator::add_score

(

double

score

)

Add to the total score. It will be weighted appropriately internally.

Definition at line 80 of file kernel/ScoreAccumulator.h.

bool IMP::kernel::ScoreAccumulator::get_abort_evaluation

(

)

const

Expensive restraints can check this during evaluation to determin if another restraint has aborted evaluation.

Definition at line 95 of file kernel/ScoreAccumulator.h.

bool IMP::kernel::ScoreAccumulator::get_is_evaluate_if_below

(

)

const

Return true if the current evaluation being done is one where scores are only consider if they are below some threshold (get_maximum()).

Definition at line 113 of file kernel/ScoreAccumulator.h.

bool IMP::kernel::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 121 of file kernel/ScoreAccumulator.h.

double IMP::kernel::ScoreAccumulator::get_maximum

(

)

const

The maximum allowed score for the Restraint::do_add_score_and_derivatives() call.
