Method Detail

getMaxPacketSize

int getMaxPacketSize()

The maximum size of a packet, not including transport layer headers

sendPacket

void sendPacket(byte[] blockToSend,
                Peer destination,
                boolean allowLocalAddresses)
         throws Peer.LocalAddressException

Send a block of encoded bytes to a peer. This is called by send, and by IncomingPacketFilter.processOutgoing(..).

Parameters:

blockToSend - The data block to send.

destination - The peer to send it to.

Throws:

Peer.LocalAddressException

getHeadersLength

int getHeadersLength()

Get the size of the transport layer headers, for byte accounting purposes.

getHeadersLength

int getHeadersLength(Peer peer)

Get the size of the transport layer headers, for byte accounting purposes.

Parameters:

peer - used to detect address family.

setLowLevelFilter

void setLowLevelFilter(IncomingPacketFilter f)

Set the decryption filter to which incoming packets will be fed

getPacketSendThreshold

int getPacketSendThreshold()

How big must the pending data be before we send a packet? *Includes* transport layer headers.

getDetectedConnectivityStatus

AddressTracker.Status getDetectedConnectivityStatus()

Does this port appear to be port forwarded? @see AddressTracker
