26  for passed object(s) of type ParticleIndexTriplet.
27 
28  Use in conjunction with various
29  restraints such as IMP::container::TripletsRestraint or
30  IMP::core::TripletRestraint. The restraints couple the score
31  functions with appropriate lists of object(s) of type ParticleIndexTriplet.
32 
33  It is possible to call the various evaluate* methods directly, but
34  this is not recommended as they do not ensure that Model invariants
35  (e.g. ScoreStates) are preserved. Use a Restraint or ScoringFunction
36  to score the model instead.
37 
38  Implementers should check out IMP_TRIPLET_SCORE().
