Examples of WKBReader

com.vividsolutions.jts.io.WKBReader
Reads a {@link Geometry}from a byte stream in Well-Known Binary format. Supports use of an {@link InStream}, which allows easy use with arbitary byte stream sources.
This class reads the format describe in {@link WKBWriter}. It also partiually handles the Extended WKB format used by PostGIS, by parsing and storing 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. @see WKBWriter
