Method Detail

process

IncomingPacketFilter.DECODED process(byte[] buf,
                                     int offset,
                                     int length,
                                     Peer peer,
                                     long now)

Process an incoming packet. This method should call USM.decodePacket() and USM.checkFilters() if necessary to decode and dispatch messages.

Parameters:

buf - The buffer to read from. Note that this may be reused later on; any data to keep must be copied.

offset - The offset to start reading from.

length - The length in bytes to read.

peer - The peer which sent us the packet. We only know the Peer because it's incoming; we are supposed to create or find PeerContext's for the Message's.

now - The exact time at which the packet was received.

Returns:

isDisconnected

boolean isDisconnected(PeerContext context)

Is the given connection closed?
