Public Member Functions
virtual std::string	type () const
	Returns a unique string identified for this constraint. Used in several places, including the ConstraintIO class. More...

virtual ConstraintOP	clone () const
	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
	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 (Vector const &X1, Vector const &X2, Vector const &Y1, Vector const &Y2) const

void	score (func::XYZ_Func const &xyz, EnergyMap const &, EnergyMap &emap) const
	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...

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...

	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
	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...

virtual ConstraintOP	remap_resid (core::id::SequenceMapping const &seqmap) const
	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
	Returns the AtomID referred to by index. More...

virtual void	show (std::ostream &out) const
	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...

virtual ConstraintOP	remapped_clone (pose::Pose const &src, pose::Pose const &dest, id::SequenceMappingCOP map=NULL) const
	Copies the data from this Constraint into a new object and returns an OP atoms are mapped to atoms with the same name in dest pose ( e.g. for switch from centroid to fullatom ) if a sequence_mapping is present it is used to map residue numbers .. NULL = identity mapping to the new object. Intended to be implemented by derived classes. More...

virtual bool	operator== (Constraint const &rhs) const
	Equality operator to test whether two constraints are functionally identical. More...

virtual bool	same_type_as_me (Constraint const &other) const
	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...

	Returns the ScoreType that this Constraint object will use. More...

virtual void	read_data (std::istream &)

	Prints the definition of a Constraint to the given std::ostream, using the given Pose, and the given func::FuncFactory.

Member Function Documentation

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.

Implements core::scoring::constraints::Constraint.

ConstraintOP core::scoring::constraints::DistancePairConstraint::clone ( ) const

virtual

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.

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.

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

virtual

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.

Implements core::scoring::constraints::Constraint.
