tcpInfo

tcpInfo
Updates and returns theTCP_INFO
for the current socket. See man 7 tcp. -
remoteAddress
Description copied from interface:Channel
Returns the remote address where this channel is connected to. The returnedSocketAddress
is supposed to be down-cast into more concrete type such asInetSocketAddress
to retrieve the detailed information.- Specified by:
remoteAddress
in interfaceChannel
- Specified by:
remoteAddress
in interfaceSocketChannel
- Overrides:
remoteAddress
in classAbstractChannel
- Returns:
- the remote address of this channel.
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
.
-
localAddress
Description copied from interface:Channel
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 interfaceSocketChannel
- Overrides:
localAddress
in classAbstractChannel
- Returns:
- the local address of this channel.
null
if this channel is not bound.
-
config
Description copied from interface:Channel
Returns the configuration of this channel.- Specified by:

-
parent
Description copied from interface:Channel
Returns the parent of this channel.- Specified by:
parent
in interfaceChannel
- Specified by:
parent
in interfaceSocketChannel
- Overrides:
parent
in classAbstractChannel
- Returns:
- the parent channel.
null
if this channel does not have a parent channel.
-
newUnsafe
Description copied from class:AbstractChannel
Create a newAbstractChannel.AbstractUnsafe
instance which will be used for the life-time of theChannel
