if theDomainDatagramChannel
is connected to the remote peer.- Specified by:
isConnected
in interfaceDomainDatagramChannel
-
localAddress

Returns the local address where this channel is bound to. The returnedSocketAddress
is supposed to be down-cast into more concrete type such asInetSocketAddress
to retrieve the detailed information.- Specified by:
localAddress
in interfaceChannel
- Specified by:
localAddress
in interfaceDomainDatagramChannel

null
if this channel is not connected. If this channel is not connected but it can receive messages from arbitrary remote addresses (e.g.DatagramChannel
, useDefaultAddressedEnvelope.recipient()
to determine the origination of the received message as this method will returnnull
.
