                                                              RTreeEntry<T> e,
                                                              int desiredInsertionLevel,
                                                              int nLevels)

Choose subtree as described in the paper.

Specified by:

chooseSubTree in interface RTreeLogic

split

public <T> org.tinspin.index.rtree.RTreeNode<T> split(org.tinspin.index.rtree.RTreeNode<T> node,
