mlpack::emst::DTBStat::DTBStat | ( | ) |
A generic initializer.
Sets the maximum neighbor distance to its default, and the component membership to -1 (no component).
mlpack::emst::DTBStat::DTBStat | ( | const TreeType & | node | ) | [inline] |
This is called when a node is finished initializing.
We set the maximum neighbor distance to its default, and if possible, we set the component membership of the node (if it has only one point and no children).
node | Node that has been finished. |

double mlpack::emst::DTBStat::bound [private] |
int mlpack::emst::DTBStat::componentMembership [private] |
The index of the component that all points in this node belong to.
This is the same index returned by UnionFind for all points in this node. If points in this node are in different components, this value will be negative.
