 ~RTConstraint () override
 destructor 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...
 
ConstraintOP clone (func::FuncOP) const override
 Clone the constraint, but where a new Func object is to be used instead. More...
 
kinematics::RT calculate_rt (func::XYZ_Func const &) const
 calculates the RT from stub1->stub2 at this instant More...
 
Real dist (func::XYZ_Func const &xyz) const override
 return the raw "distance" before that distance is handed to the FUNC object More...
 
void score (func::XYZ_Func const &xyz_func, EnergyMap const &weights, 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...
 
std::string type () const override
 Returns a unique string identified for this constraint. Used in several places, including the ConstraintIO class. 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...

 Returns the AtomID referred to by index. More...
 
void fill_f1_f2 (AtomID const &atom, func::XYZ_Func const &xyz, Vector &F1, Vector &F2, EnergyMap const &weights) const override
 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...
 
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...
 
ConstraintOP remapped_clone (pose::Pose const &src, pose::Pose const &dest, id::SequenceMappingCOP map=nullptr) const override
 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 .. nullptr = identity mapping to the new object. Intended to be implemented by derived classes. 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...

virtual void show_def (std::ostream &, pose::Pose const &) const
 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...

id::AtomID const & core::scoring::constraints::RTConstraint::atom ( Size const  index) const
overridevirtual

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.

kinematics::RT core::scoring::constraints::RTConstraint::calculate_rt ( func::XYZ_Func const &  xyz) const

calculates the RT from stub1->stub2 at this instant

References core::id::StubID::atom(), stub1_, stub2_, and protocols::kinmatch::xyz().

Referenced by dist(), and fill_f1_f2().

ConstraintOP core::scoring::constraints::RTConstraint::clone ( ) const
overridevirtual

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.

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

References RTConstraint().

ConstraintOP core::scoring::constraints::RTConstraint::clone ( func::FuncOP  new_func) const
overridevirtual

Clone the constraint, but where a new Func object is to be used instead.

Real core::scoring::constraints::RTConstraint::dist ( func::XYZ_Func const &  xyz) const

return the raw "distance" before that distance is handed to the FUNC object

EnergyMap const &  weights 
) const
overridevirtual

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!)

func::Func const & core::scoring::constraints::RTConstraint::get_func ( ) const
overridevirtual

Returns the func::Func object associated with this Constraint object.

Reimplemented from core::scoring::constraints::Constraint.

References func_.

Size core::scoring::constraints::RTConstraint::natoms ( ) const
overridevirtual

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.

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.

bool core::scoring::constraints::RTConstraint::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.

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

ConstraintOP core::scoring::constraints::RTConstraint::remapped_clone ( pose::Pose const &  src,
pose::Pose const &  dest,
id::SequenceMappingCOP  map = nullptr 
) const
overridevirtual

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 .. nullptr = identity mapping to the new object.

bool core::scoring::constraints::RTConstraint::same_type_as_me ( Constraint const &  other) const
overridevirtual

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.

void core::scoring::constraints::RTConstraint::score ( func::XYZ_Func const &  xyz_func,
EnergyMap const &  weights,
EnergyMap emap 
) const
overridevirtual

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.

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

References dist(), func_, and core::scoring::constraints::Constraint::score_type().

void core::scoring::constraints::RTConstraint::show ( std::ostream &  ) const
