Function Documentation

◆ CloneForest()

template<class FOREST >
FastVector<std::shared_ptr<typename FOREST::Node> > gtsam::treeTraversal::CloneForest ( const FOREST &  forest)

Clone a tree, copy-constructing new nodes (calling std::make_shared) and setting up child pointers for a clone of the original tree.

Parameters
forestThe forest of trees to clone. The method forest.roots() should exist and return a collection of shared pointers to FOREST::Node.
Returns
The new collection of roots.

◆ DepthFirstForest() [1/2]

template<class FOREST , typename DATA , typename VISITOR_PRE >
void gtsam::treeTraversal::DepthFirstForest ( FOREST &  forest,
DATA &  rootData,
VISITOR_PRE &  visitorPre 
)

Traverse a forest depth-first, with a pre-order visit but no post-order visit.

Parameters
forestThe forest of trees to traverse. The method forest.roots() should exist and return a collection of (shared) pointers to FOREST::Node.
visitorPrevisitorPre(node, parentData) will be called at every node, before visiting its children, and will be passed, by reference, the DATA object returned by the visit to its parent. Likewise, visitorPre should return the DATA object to pass to the children. The returned DATA object will be copy-constructed only upon returning to store internally, thus may be modified by visiting the children. Regarding efficiency, this copy-on-return is usually optimized out by the compiler.
rootDataThe data to pass by reference to visitorPre when it is called on each root node.

◆ DepthFirstForest() [2/2]

template<class FOREST , typename DATA , typename VISITOR_PRE , typename VISITOR_POST >
void gtsam::treeTraversal::DepthFirstForest ( FOREST &  forest,
DATA &  rootData,
VISITOR_PRE &  visitorPre,
VISITOR_POST &  visitorPost 
)

Traverse a forest depth-first with pre-order and post-order visits.

Parameters
forestThe forest of trees to traverse. The method forest.roots() should exist and return a collection of (shared) pointers to FOREST::Node.
visitorPrevisitorPre(node, parentData) will be called at every node, before visiting its children, and will be passed, by reference, the DATA object returned by the visit to its parent. Likewise, visitorPre should return the DATA object to pass to the children. The returned DATA object will be copy-constructed only upon returning to store internally, thus may be modified by visiting the children. Regarding efficiency, this copy-on-return is usually optimized out by the compiler.
visitorPostvisitorPost(node, data) will be called at every node, after visiting its children, and will be passed, by reference, the DATA object returned by the call to visitorPre (the DATA object may be modified by visiting the children).
rootDataThe data to pass by reference to visitorPre when it is called on each root node.

Definition at line 77 of file treeTraversal-inst.h.

◆ DepthFirstForestParallel()

template<class FOREST , typename DATA , typename VISITOR_PRE , typename VISITOR_POST >
void gtsam::treeTraversal::DepthFirstForestParallel ( FOREST &  forest,
DATA &  rootData,
VISITOR_PRE &  visitorPre,
VISITOR_POST &  visitorPost,
int  problemSizeThreshold = 10 
)

Traverse a forest depth-first with pre-order and post-order visits.

Parameters
forestThe forest of trees to traverse. The method forest.roots() should exist and return a collection of (shared) pointers to FOREST::Node.
rootDataThe data to pass by reference to visitorPre when it is called on each root node.
visitorPrevisitorPre(node, parentData) will be called at every node, before visiting its children, and will be passed, by reference, the DATA object returned by the visit to its parent. Likewise, visitorPre should return the DATA object to pass to the children. The returned DATA object will be copy-constructed only upon returning to store internally, thus may be modified by visiting the children.

visitorPostvisitorPost(node, data) will be called at every node, after visiting its children, and will be passed, by reference, the DATA object returned by the call to visitorPre (the DATA object may be modified by visiting the children).

◆ GatherStatistics()

template<class FOREST >
ForestStatistics gtsam::treeTraversal::GatherStatistics ( const FOREST &  forest)

Definition at line 86 of file statistics.h.

◆ PrintForest()

template<class FOREST >
void gtsam::treeTraversal::PrintForest ( const FOREST &  forest,
std::string  str,
const KeyFormatter keyFormatter 
)

Print a tree, prefixing each line with str, and formatting keys using keyFormatter. To print each node, this function calls the print function of the tree nodes.
