Description copied from interface: Packet

Writes this packet to the OutputStream with the supplied payload. You can use this method to e.g. write a raw UDPPacket to the stream with this payload. Note, if the UDPPacket already had a payload it will be ignored so use this method with care.

Specified by:

write in interface Packet

Throws:

IOException
