Enclosing interface:

BookieProtocol

public static final class BookieProtocol.PacketHeader
extends Object

The first int of a packet is the header. It contains the version, opCode and flags. The initial versions of BK didn't have this structure and just had an int representing the opCode as the first int. This handles that case also.
