Constructor & Destructor Documentation

◆ Factor() [1/2]

template<typename CONTAINER>

gtsam::Factor::Factor ( const CONTAINER & keys )

inlineexplicitprotected

Construct factor from container of keys.

This constructor is used internally from derived factor constructors, either from a container of keys or from a boost::assign::list_of.

◆ Factor() [2/2]

template<typename ITERATOR>

gtsam::Factor::Factor	(	ITERATOR	first,
		ITERATOR	last )

inlineprotected

Construct factor from iterator keys.

This constructor may be used internally from derived factor constructors, although our code currently does not use this.

Member Function Documentation

◆ error()

double gtsam::Factor::error ( const HybridValues & c ) const

virtual

All factor types need to implement an error function.

In factor graphs, this is the negative log-likelihood.

Reimplemented in gtsam::DecisionTreeFactor, gtsam::DiscreteConditional, gtsam::DiscreteFactor, gtsam::GaussianFactor, gtsam::GaussianMixture, gtsam::GaussianMixtureFactor, gtsam::HessianFactor, gtsam::HybridConditional, gtsam::JacobianFactor, gtsam::MixtureFactor, gtsam::NonlinearFactor, gtsam::SymbolicConditional, and gtsam::SymbolicFactor.

◆ FromIterators()

template<typename ITERATOR>

Factor gtsam::Factor::FromIterators	(	ITERATOR	first,
		ITERATOR	last )

inlinestaticprotected

Construct factor from iterator keys.

This is called internally from derived factor static factor methods, as a workaround for not being able to call the protected constructors above.

◆ FromKeys()

template<typename CONTAINER>

Factor gtsam::Factor::FromKeys ( const CONTAINER & keys )

inlinestaticprotected

Construct factor from container of keys.

This is called internally from derived factor static factor methods, as a workaround for not being able to call the protected constructors above.

◆ keys()

KeyVector & gtsam::Factor::keys ( )

inline

Returns: keys involved in this factor

◆ print()

void gtsam::Factor::print	(	const std::string &	s = "Factor",
		const KeyFormatter &	formatter = DefaultKeyFormatter ) const

virtual
