gtsam::ClusterTree< GRAPH > Class Template Reference

Detailed Description

template<class GRAPH>
class gtsam::ClusterTree< GRAPH >

A cluster-tree is associated with a factor graph and is defined as in Koller-Friedman: each node k represents a subset \( C_k \sub X \), and the tree is family preserving, in that each factor \( f_i \) is associated with a single cluster and \( scope(f_i) \sub C_k \).

Standard Constructors

 ClusterTree (const This &other)
 Copy constructor - makes a deep copy of the tree structure, but only pointers to factors are copied, factors are not cloned.
 

Testable

void print (const std::string &s="", const KeyFormatter &keyFormatter=DefaultKeyFormatter) const
 Print the cluster tree.
 

Advanced Interface

void addRoot (const boost::shared_ptr< Cluster > &cluster)
 
void addChildrenAsRoots (const boost::shared_ptr< Cluster > &cluster)
 
size_t nrRoots () const
 
const FastVector< sharedNode > & roots () const
 Return the set of roots (one for a tree, multiple for a forest)
 
const Clusteroperator[] (size_t i) const
 

Details

Thisoperator= (const This &other)
 Assignment operator - makes a deep copy of the tree structure, but only pointers to factors are copied, factors are not cloned.
