Public Member Functions

std::string type () const override
 Returns a unique string identified for this constraint. Used in several places, including the ConstraintIO class. More...
 
ConstraintOP clone () const override
 Copies the data from this Constraint into a new object and returns an OP to the new object. Intended to be implemented by derived classes and used by pose.add_constraint. This function must return a deep copy of itself – meaning that if this Constraint holds pointers to other Constraints that it must invoke clone on those Constraints as well. If the Constraint holds a FuncOP, then the Func should also be cloned. More...
 
Size show_violations (std::ostream &out, pose::Pose const &pose, Size verbose_level, Real threshold=1) const override
 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...
 
void read_def (std::istream &in, pose::Pose const &pose, func::FuncFactory const &func_factory) override
 
bool operator== (Constraint const &rhs) const override
 Equality operator to test whether two constraints are functionally identical. More...
 
bool same_type_as_me (Constraint const &other) const override
 Determine if the calling class has the same type as the input class, using dynamic casts. This is important in ensuring that two constraints are equal: both this and other must check that the other is the same as it. This is not an optional method and every class should implement it, regaurdless of whether a parent class implements it. More...

void score (func::XYZ_Func const &xyz, EnergyMap const &, EnergyMap &emap) const override
 Calculates a score for this constraint using XYZ_Func, and puts the UNWEIGHTED score into emap. Although the current set of weights currently is provided, Constraint objects should put unweighted scores into emap because the ScoreFunction will do the weighting itself. More...

 Fill the f1 and f2 vectors, necessary for considering the derivative this constraint during minimization. (someone please reference Bill Wedermeyer's paper here, as I'm in an airport and can't fill it in myself!) More...

 c-tor More...
 
Size natoms () const override
 Returns the number of atoms involved in defining this constraint. If the constraint doesn't depend on particular atoms (e.g. a residue type constraint) this function can return zero. More...
 
ConstraintOP remap_resid (core::id::SequenceMapping const &seqmap) const override
 apply a resid remapping to this constraint, returns the remapped constraint Does this return an owning pointer to this constraint or a copy? Documentation would be nice. More...
 
AtomID const & atom (Size const n) const override
 Returns the AtomID referred to by index. More...
 
void show_def (std::ostream &, pose::Pose const &) const override
 Prints the definition of a Constraint to the given std::ostream, using the given Pose, and the given func::FuncFactory. This method is intended to be overridden by derived classes if they'd like to use the ConstraintIO machinery. It's also not clear why this method takes a Pose, other than to be symmetric with read_def. More...
 
void show (std::ostream &out) const override
 This method is intended to show the value of the Constraint function evaluated over some reasonable range of values. For example, a constraint between pairs of atoms might show the values of the Constraint function between 4 and 12 angstroms. More...

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.

bool core::scoring::constraints::DihedralPairConstraint::operator== ( Constraint const &  ) const
overridevirtual

Equality operator to test whether two constraints are functionally identical.

This operator should use floating point comparison and should not decide that two floats are identical if they are within some epsilon > 0. This method allows developes to remove specific constraints from Poses, even if the constraints have been cloned. Remapped constraints should not be considered identical – i.e., if cst1 is between residues i and j and cst2 is between residues i+1 and j+1. All subclasses of Constraint must implement this method.
