Package org.locationtech.jts.index.strtree

Class SIRtree

java.lang.Object

org.locationtech.jts.index.strtree.AbstractSTRtree

org.locationtech.jts.index.strtree.SIRtree

All Implemented Interfaces:

java.io.Serializable

public class SIRtree
extends AbstractSTRtree

One-dimensional version of an STR-packed R-tree. SIR stands for "Sort-Interval-Recursive". STR-packed R-trees are described in: P. Rigaux, Michel Scholl and Agnes Voisard. Spatial Databases With Application To GIS. Morgan Kaufmann, San Francisco, 2002.

This class is thread-safe. Building the tree is synchronized, and querying is stateless.
