Class WKBReader

java.lang.Object
  extended bycom.vividsolutions.jts.io.WKBReader

public class WKBReader
extends java.lang.Object

Reads a Geometryfrom a byte stream in Well-Known Binary format. Supports use of an InStream, which allows easy use with arbitary byte stream sources.

This class reads the format describe in WKBWriter. It also partiually handles the Extended WKB format used by PostGIS (by reading SRID values)

This class is designed to support reuse of a single instance to read multiple geometries. This class is not thread-safe; each thread should create its own instance.
