2D-Tree is an implementation 2-dimensional tree for range and nearest neighbors searches.
buildTree(List<Node<T>> nodes
- builds balanced 2d-treeinsert(T object, double x, double y)
- inserts object into the treeinsertOrUpdate(T object, double x, double y)
- inserts object if it doesn't exists in the tree otherwise updates the existing objectdelete(T object)
- deletes object from the tree
findNearestNeighbour(double x, double y)
- finds the nearest neighborfindNearestNeighbours(double x, double y, int k)
- finds k nearest neighborsrangeSearch(double x, double y, double radius)
- finds neighbors in specified rangerangeSearchKm(double x, double y, double radius)
- finds neighbors in specified range assuming thatx
is a latitude,y
- longitude,radius
- radius in km.
