#include <IMP/ScoreState.h>
Inheritance diagram for IMP::ScoreState:ScoreStates maintain invariants in the Model.
ScoreStates allow actions to be taken before and after the restraint evaluation process. Such code can be used to, for example:
ScoreStates have two methods which are called during the Model::evaluate() function
The Model uses information that the ScoreState reports about its input and output containers and particles to determine a safe order in which all the ScoreState objects registered in the model can be applied. That is, the Model will ensure that a ScoreState that has Particle A in its output list is applied before a ScoreState that has A in its input list. For ScoreState::before_evaluate(), Input and output lists are returned by the respective get_input_* and get_output_* calls. For ScoreState::after_evaluate() they are reversed (see note below).

Update the state given the current state of the model.
This is also called prior to every calculation of the model score. It should be implemented by ScoreStates in order to provide functionality.

| bool IMP::ScoreState::get_can_skip | ( | ) | const |
Get whether this state can be skipped if its inputs/outputs didn't move.
During Monte Carlo and other types of sampling that only move parts of the system, ScoreStates where this returns true may be skipped at model evaluation time if none of the inputs or outputs moved since the last evaluation.

Set whether we can skip during model evaluation if appropriate.
This should be set only once before the state is used (ideally in the constructor), and can be used for ScoreStates that can safely be skipped if their inputs or outputs didn't move. For example, a state that expects to log every N frames should not be skipped. By default, states are not skipped.
