config
Description copied from interface:Channel
Returns the configuration of this channel.- Specified by:
config
in interfaceChannel
- Specified by:
config
in interfaceDomainDatagramChannel
- Specified by:
config
in classAbstractEpollChannel
-
doBind
Description copied from class:AbstractChannel
Bind theChannel
to theSocketAddress
- Overrides:
doBind
in classAbstractEpollChannel
- Throws:
Exception
-
doClose
Description copied from class:AbstractChannel
Close theChannel
- Overrides:
doClose
in classAbstractEpollChannel
- Throws:
Exception
-
doConnect
protected boolean doConnect(SocketAddress remoteAddress, SocketAddress localAddress) throws Exception Description copied from class:AbstractEpollChannel
Connect to the remote peer- Overrides:
doConnect
in classAbstractEpollChannel
- Throws:
Exception
-
doDisconnect
Description copied from class:AbstractChannel
Disconnect thisChannel
from its remote peer- Overrides:
doDisconnect
in classAbstractEpollChannel
- Throws:
Exception
-
doWrite
Description copied from class:AbstractChannel
Flush the content of the given buffer to the remote peer.- Specified by:
doWrite
in classAbstractChannel
- Throws:
Exception
-
doWriteMessage
- Throws:
Exception
-
filterOutboundMessage
Description copied from class:AbstractChannel
Invoked when a new message is added to aChannelOutboundBuffer
of thisAbstractChannel
, so that theChannel
implementation converts the message to another. (e.g. heap buffer -> direct buffer)- Overrides:
filterOutboundMessage
in classAbstractChannel
-
isActive
public boolean isActive()Description copied from interface:Channel
Returntrue
if theChannel
is active and so connected.- Specified by:
isActive
in interfaceChannel
- Overrides:
isActive
in classAbstractEpollChannel
-
isConnected
public boolean isConnected()Description copied from interface:DomainDatagramChannel
Returntrue
if theDomainDatagramChannel
is connected to the remote peer.- Specified by:
isConnected
in interfaceDomainDatagramChannel
-
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 interfaceDomainDatagramChannel
- Overrides:
localAddress
in classAbstractChannel
- Returns:
- the local address of this channel.
null
if this channel is not bound.
-

in classAbstractEpollChannel
-
metadata
Description copied from interface:Channel
- Specified by:
metadata

-
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 interfaceDomainDatagramChannel
- Overrides:
remoteAddress
in classAbstractChannel

- 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
.
-
remoteAddress0
Description copied from class:AbstractChannel
Return theSocketAddress
which theChannel
is connected to.- Overrides:
