Method Details

isCompatible

protected boolean isCompatible(EventLoop loop)

Description copied from class: AbstractChannel

Return true if the given EventLoop is compatible with this instance.

Overrides:

isCompatible in class AbstractEpollServerChannel

doBind

protected void doBind(SocketAddress localAddress)
               throws Exception

Description copied from class: AbstractChannel

Bind the Channel to the SocketAddress

Overrides:

doBind in class AbstractEpollChannel

Throws:

Exception

remoteAddress

public InetSocketAddress remoteAddress()

Description copied from interface: Channel

Returns the remote address where this channel is connected to. The returned SocketAddress is supposed to be down-cast into more concrete type such as InetSocketAddress to retrieve the detailed information.

Specified by:

remoteAddress in interface Channel

Specified by:

remoteAddress in interface ServerSocketChannel

Overrides:

remoteAddress in class AbstractChannel

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, use DefaultAddressedEnvelope.recipient() to determine the origination of the received message as this method will return null.

localAddress

public InetSocketAddress localAddress()

Description copied from interface: Channel

Returns the local address where this channel is bound to. The returned SocketAddress is supposed to be down-cast into more concrete type such as InetSocketAddress to retrieve the detailed information.

Specified by:

localAddress in interface Channel

Specified by:

localAddress in interface ServerSocketChannel

Overrides:

localAddress in class AbstractChannel

Returns:

the local address of this channel. null if this channel is not bound.

config

public EpollServerSocketChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

Specified by:

config in interface ServerSocketChannel

Specified by:

config in class AbstractEpollChannel

newChildChannel

protected Channel newChildChannel(int fd,
 byte[] address,
 int offset,
 int len)
                           throws Exception

Specified by:

newChildChannel in class AbstractEpollServerChannel

Throws:

Exception

tcpMd5SigAddresses

Collection<InetAddress> tcpMd5SigAddresses()

setTcpMd5Sig

void setTcpMd5Sig(Map<InetAddress,byte[]> keys)
           throws IOException

Throws:

IOException
