gtsam::Scatter Class Reference

Detailed Description

Scatter is an intermediate data structure used when building a HessianFactor incrementally, to get the keys in the right order.

The "scatter" is a map from global variable indices to slot indices in the union of involved variables. We also include the dimensionality of the variable.

Public Member Functions
	Scatter (const GaussianFactorGraph &gfg, boost::optional< const Ordering & > ordering=boost::none)
Public Member Functions inherited from gtsam::FastMap< Key, SlotEntry >
	FastMap ()
	Default constructor.
	FastMap (INPUTITERATOR first, INPUTITERATOR last)
	Constructor from a range, passes through to base class.
	FastMap (const FastMap< Key, SlotEntry > &x)
	Copy constructor from another FastMap.
	FastMap (const Base &x)
	Copy constructor from the base map class.
	operator std::map< Key, SlotEntry > () const
	Conversion to a standard STL container.
bool	insert2 (const Key &key, const SlotEntry &val)
	Handy 'insert' function for Matlab wrapper.
bool	exists (const Key &e) const
	Handy 'exists' function.
