Class AiShapeWriter

java.lang.Object

hec.map.aishape.AiShapeWriter

public class AiShapeWriter
extends Object

A shape writer class that will write shapes and shape attributes in a stream. This class does not require that all data be loaded a ahead of time (i.e. AiShapeMap). This works well for applications that use large amounts of data that need to be written to shape files.
