25 * <code>WKBFactory3D</code> must be implemented by any class wishing to serve as a factory
26 * for geometric objects. When an object implements this interface, it can be submitted
27 * to the <code>WKBParser</code> and it will call thoses methods with the correct values.
28 * The author of each factory is completly free to implement any behavior, including ignoring some calls.<br/>
29 *
30 * wkbByteOrders and wkbTypes values don't generate events because there is no point in doing so.
31 * Similarly, there is no way to pass a generic Geometry. MultiPoints, WKBPoints and Points are colapsed in a double array.
32 * It is the responsability of the Factory to ensure that the stream of events actually represents a correct construction.
33 * See AbstractWKBFactory for an implementation of a "validating" WKBFactory.
34 *
35 * <br/>Inspired by the SAX API.
