Interface SpatialNode<N extends SpatialNode<N,E>,E extends SpatialEntry>

All Superinterfaces:

Externalizable, Node<N,E>, Page<N>, Serializable, SpatialComparable, SpatialObject

All Known Implementing Classes:

AbstractRStarTreeNode, DeLiCluNode, RdKNNNode, RStarTreeNode

public interface SpatialNode<N extends SpatialNode<N,E>,E extends SpatialEntry>
extends Node<N,E>, SpatialObject

Defines the requirements for an object that can be used as a node in a Spatial Index. A spatial node can be a spatial directory node or a spatial leaf node.
