gtsam::MetisIndex Class Reference

Detailed Description

The MetisIndex class converts a factor graph into the Compressed Sparse Row format for use in METIS algorithms.

Specifically, two vectors store the adjacency structure of the graph. It is built from a factor graph prior to elimination, and stores the list of factors that involve each variable.

Standard Constructors
	MetisIndex ()
	Default constructor, creates empty MetisIndex.
template<class FG >
	MetisIndex (const FG &factorGraph)
	~MetisIndex ()

Advanced Interface
template<class FACTOR >
void	augment (const FactorGraph< FACTOR > &factors)
	Augment the variable index with new factors. More...
const std::vector< int32_t > &	xadj () const
const std::vector< int32_t > &	adj () const
size_t	nValues () const
Key	intToKey (int32_t value) const

Public Types
typedef boost::shared_ptr< MetisIndex >	shared_ptr
typedef boost::bimap< Key, int32_t >	bm_type

Member Function Documentation

augment()

template<class FACTOR >

void gtsam::MetisIndex::augment

(

const FactorGraph< FACTOR > &

factors

)

Augment the variable index with new factors.

This can be used when solving problems incrementally.
