Detailed Description

Writes a Geometry into Well-Known Binary format.

The WKB format is specified in the OGC Simple Features for SQL specification. This implementation supports the extended WKB standard for representing 3-dimensional coordinates. The presence of 3D coordinates is signified by setting the high bit of the wkbType word.

Empty Points cannot be represented in WKB; an IllegalArgumentException will be thrown if one is written. The WKB specification does not support representing LinearRing they will be written as LineString

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.
