Detailed Description

template<class NodeKey, class NodeData, class NodeDataItem, class NodeDataTag = kd_node_m_datasingle_tag>
class te::sam::kdtree::Node< NodeKey, NodeData, NodeDataItem, NodeDataTag >

A class that represents an Kd-tree node.

Each node contains a pointer to its left and right subtree (NULL if it is not set), one key used for insertion of the data into the tree.

Note: The key must have methods called getX() and getY().; These kind of node stores the data in each node.; The nodes may contains one single element (kd_node_m_datasingle_tag) or a set of values (kd_node_m_dataset_tag).; If the node type is kd_node_m_datasingle_tag than NodeData and NodeDataItem are the same types. And if one entry with the same key already exist, so they will be overwrite.; If the node type is kd_node_m_dataset_tag than NodeData mus have a method called push_back(NodeDataItem) that permits to store elements with the same key in the node.
