Size show_violations (std::ostream &out, pose::Pose const &pose, Size verbose_level, Real threshold=1) const
 Prints the violations of this constraint to the given std::ostream. What are violations? It's not defined, and it depends on the constraint and the function! also - wtf is threshold? it was defined as a Size in CoordinateConstraint, I don't know which definition is the right one. Documentation would be nice ... More...

Real score (conformation::Conformation const &conformation) const
 Returns the score of this constraint computed over the given conformation. Not necessarily implemented in all derived classes, as it's redundant with the score( XYZ_Func, EnergyMap, EnergyMap ) method defined above. Returns 0.0 if not implemented. More...

 Prints the definition of a Constraint to the given std::ostream, using the given Pose, and the given FuncFactory. This method is intended to be overridden by derived classes if they'd like to use the ConstraintIO machinery.

id::AtomID const & core::scoring::constraints::DistancePairConstraint::atom ( Size const  index) const
virtual

Returns the AtomID referred to by index.

Note that this function isn't actually used by the constraint scoring machenery. If you're calling it on a generic Constraint (as opposed to specifically on a derived class) you're probably doing something wrong.
