Constructor & Destructor Documentation

IMP::example::ExampleRestraint::ExampleRestraint ( kernel::Model *  m,
kernel::ParticleIndex  p,
double  k 
)

kernel::Restraints should store the particles they are to act on, preferably in a Singleton or PairContainer as appropriate.

Member Function Documentation

void IMP::example::ExampleRestraint::do_add_score_and_derivatives ( kernel::ScoreAccumulator  sa) const
virtual

A restraint should override this to compute the score and derivatives.

Reimplemented from IMP::kernel::Restraint.

kernel::ModelObjectsTemp IMP::example::ExampleRestraint::do_get_inputs ( ) const
virtual

Get any Particle, Container or other ModelObjects read by this during evaluation. If you read everything in a container, you can just return that container.

Implements IMP::kernel::ModelObject.
