Detailed Description

Reads a Geometry from Well-Known Binary format.

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.

The Well-known Binary format is defined in the OpenGIS Simple Features Specification for SQL. This implementation supports the extended WKB standard which allows representing 3-dimensional coordinates.
