dispatchIncomingPacket

public abstract List<IQ> dispatchIncomingPacket(IQ iq,
                              String id)
                                         throws XMPPException,
                                                SmackException

Dispatch an incoming packet. The negotiators form a tree relationship that roughly matches the Jingle packet format: JingleSession Content Negotiator Media Negotiator Transport Negotiator Content Negotiator Media Negotiator Transport Negotiator This way, each segment of a Jingle packet has a corresponding negotiator that know how to deal with that part of the Jingle packet. It also allows us to support Jingle packets of arbitraty complexity. Each parent calls dispatchIncomingPacket for each of its children. The children then pass back a List<> of results that will get sent when we reach the top level negotiator (JingleSession).

Parameters:

iq - the packet received

id - the ID of the response that will be sent

Returns:

the new packet to send (either a Jingle or an IQ error).

Throws:

XMPPException

SmackException

start

public void start()

isStarted

public boolean isStarted()

doStart

protected abstract void doStart()

Each of the negotiators has their individual behavior when they start.

close

public void close()

Close the negotiation.
