public abstract class PacketOutputStream
PacketOutputStream is an I/O stream used for sending Packets to the network, or dumping them to a tcpdump-formatted file, depending on how the stream was created.
The close()
and flush()
methods close and flush the output file respectively.
For a stream created for sending, they do nothing.

Packet.setChecksums()
,
so checksums &c are not the application's problem,
at least for packet classes which correctly
implement Packet.setChecksums()
.
packet
- Packet to write.
IOException
- Some I/O problem sending or dumping the packet.
