Method Detail

getInetSocketAddressLookup

protected Cancellable getInetSocketAddressLookup(InetSocketAddress bindAddress,
                                                 Continuation<InetSocketAddressLookup,IOException> deliverResultToMe)

Get the address from the transport layer. Used by the two public methods. Does the execution on the selector, calls back on the continuation on the selector.

findExternalNodes

public Cancellable findExternalNodes(InetSocketAddress local,
                                     Collection<InetSocketAddress> probeAddresses,

Call this to find some nodes outside your firewall.

Specified by:

findExternalNodes in interface ConnectivityVerifier

Parameters:

local - the local bindaddress
