Inheritance diagram for gtsam::ISAM2Clique:Public Member Functions | |
| ISAM2Clique () | |
| Default constructor. | |
| ISAM2Clique (const ISAM2Clique &other) | |
| Copy constructor, does not copy solution pointers as these are invalid in different trees. | |
| ISAM2Clique & | operator= (const ISAM2Clique &other) |
| Assignment operator, does not copy solution pointers as these are invalid in different trees. | |
| void | setEliminationResult (const FactorGraphType::EliminationResult &eliminationResult) |
| Overridden to also store the remaining factor and gradient contribution. | |
| Base::FactorType::shared_ptr & | cachedFactor () |
| Access the cached factor. | |
| const Vector & | gradientContribution () const |
| Access the gradient contribution. | |
| bool | equals (const This &other, double tol=1e-9) const |
| void | print (const std::string &s="", const KeyFormatter &formatter=DefaultKeyFormatter) const |
| print this node | |
