Detailed Description

template<class L>
class gtsam::Assignment< L >

An assignment from labels to value index (size_t). Assigns to each label a value. Implemented as a simple map. A discrete factor takes an Assignment and returns a value.

Member Function Documentation

◆ CartesianProduct()

template<class L >
template<typename Derived = Assignment<L>>
static std::vector<Derived> gtsam::Assignment< L >::CartesianProduct ( const std::vector< std::pair< L, size_t >> &  keys)
inlinestatic

Get Cartesian product consisting all possible configurations.

Parameters
vectorlist of keys (label,cardinality) pairs.
Returns
vector list of all possible value assignments

This function returns a vector of Assignment values for all possible (Cartesian product) configurations of set of Keys which are nothing but (Label,cardinality) pairs. This function should NOT be called for more than a small number of variables and cardinalities. E.g. For 6 variables with each having cardinalities 4, we get 4096 possible configurations!!

◆ DefaultFormatter()

template<class L >
static std::string gtsam::Assignment< L >::DefaultFormatter ( const L x)
inlinestaticprivate

Default method used by labelFormatter or valueFormatter when printing.

Parameters
xThe value passed to format.
Returns
std::string

◆ equals()

template<class L >
bool gtsam::Assignment< L >::equals ( const Assignment< L > &  other,
double  tol = 1e-9 
) const

◆ print()

template<class L >

const std::function< std::string(L)> &  labelFormatter = &DefaultFormatter 
) const
