Class PacketHeaderDataOutputStream

java.lang.Object
  CADI.Server.LogicalTarget.JPEG2000.Codestream.PacketHeaderDataOutputStream

public class PacketHeaderDataOutputStream
extends java.lang.Object

This class implements a data output stream for the packet header encoder machinery. It includes all necessary bits to ensure that the packet header will not contain any of code-stream's delimiting marker codes (0xFF90 to 0xFFFF).
