error()

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

overridevirtualinherited

All factor types need to implement an error function. In factor graphs, this is the negative log-likelihood.

Reimplemented from gtsam::Factor.

FromIterators()

template<typename ITERATOR >

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

inlinestaticprotectedinherited

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 >

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

inlinestaticprotectedinherited

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 ( )

inlineinherited

Returns

keys involved in this factor

size()

size_t gtsam::Factor::size ( ) const

inlineinherited

Returns

the number of variables involved in this factor
