All Implemented Interfaces:

Closeable, DataInput, AutoCloseable, SWFConstants

public class SWFInputStream
extends org.freehep.util.io.TaggedInputStream
implements SWFConstants

This class extends the TaggedInputStream with several methods to read SWF primitives from the stream and to read TagHeaders. It also handles the management of the SWFDictionary.
