Constructor Details

NioSocketChannel

public NioSocketChannel(Channel parent,
 ChannelFactory factory,
 ChannelPipeline pipeline,
 ChannelSink sink,
 SocketChannel socket,
 NioWorker worker)

Method Details

getWorker

public NioWorker getWorker()

Description copied from class: AbstractNioChannel

Return the AbstractNioWorker that handle the IO of the AbstractNioChannel

Overrides:

getWorker in class AbstractNioChannel<SocketChannel>

Returns:

worker

getConfig

public NioSocketChannelConfig getConfig()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

getConfig in interface Channel

Specified by:

getConfig in interface SocketChannel

Specified by:

getConfig in class AbstractNioChannel<SocketChannel>

isOpen

public boolean isOpen()

Description copied from interface: Channel

Returns true if and only if this channel is open.

Specified by:

isOpen in interface Channel

Overrides:

isOpen in class AbstractChannel

isBound

public boolean isBound()

Description copied from interface: Channel

Returns true if and only if this channel is bound to a local address.

Specified by:

isBound in interface Channel

isConnected

public boolean isConnected()

Description copied from interface: Channel

Returns true if and only if this channel is connected to a remote address.

Specified by:

isConnected in interface Channel

setBound

final void setBound()

setConnected

final void setConnected()

setClosed

protected boolean setClosed()

Description copied from class: AbstractChannel

Marks this channel as closed. This method is intended to be called by an internal component - please do not call it unless you know what you are doing.

Overrides:

setClosed in class AbstractNioChannel<SocketChannel>

Returns:

true if and only if this channel was not marked as closed yet

getLocalSocketAddress

InetSocketAddress getLocalSocketAddress()
                                 throws Exception

Specified by:

getLocalSocketAddress in class AbstractNioChannel<SocketChannel>

Throws:

Exception

getRemoteSocketAddress

InetSocketAddress getRemoteSocketAddress()
                                  throws Exception

Specified by:

getRemoteSocketAddress in class AbstractNioChannel<SocketChannel>

Throws:

Exception

write

public ChannelFuture write(Object message,
 SocketAddress remoteAddress)

Description copied from interface: Channel

Sends a message to this channel asynchronously. It has an additional parameter that allows a user to specify where to send the specified message instead of this channel's current remote address. If this channel was created by a connectionless transport (e.g. DatagramChannel) and is not connected yet, you must specify non-null address. Otherwise, the write request will fail with NotYetConnectedException and an 'exceptionCaught' event will be triggered.

Specified by:

write in interface Channel

Overrides:

write in class AbstractChannel

Parameters:

message - the message to write

remoteAddress - where to send the specified message. This method is identical to Channel.write(Object) if null is specified here.

Returns:

the ChannelFuture which will be notified when the write request succeeds or fails
