Examples of com.vividsolutions.jts.io.WKBWriter

com.vividsolutions.jts.io.WKBWriter
Writes a {@link Geometry} into Well-Known Binary format.Supports use of an {@link OutStream}, which allows easy use with arbitary byte stream sinks.
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 {@link IllegalArgumentException} will be thrown if one iswritten. The WKB specification does not support representing {@link LinearRing}s; they will be written as {@link LineString}s.
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 WKBReader
