Method Details

tcpInfo

public EpollTcpInfo tcpInfo()

Returns the TCP_INFO for the current socket. See man 7 tcp.

tcpInfo

public EpollTcpInfo tcpInfo(EpollTcpInfo info)

Updates and returns the TCP_INFO for the current socket. See man 7 tcp.

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 SocketChannel

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 SocketChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

config

public EpollSocketChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

Specified by:

config in interface SocketChannel

Specified by:

config in class AbstractEpollChannel

parent

public ServerSocketChannel parent()

Description copied from interface: Channel

Returns the parent of this channel.

Specified by:

parent in interface Channel

Specified by:

parent in interface SocketChannel

Overrides:

parent in class AbstractChannel

Returns:

the parent channel. null if this channel does not have a parent channel.

newUnsafe

protected AbstractEpollChannel.AbstractEpollUnsafe newUnsafe()

Description copied from class: AbstractChannel

Create a new AbstractChannel.AbstractUnsafe instance which will be used for the life-time of the Channel

Overrides:

newUnsafe in class AbstractEpollStreamChannel

doConnect0

boolean doConnect0(SocketAddress remote)
            throws Exception

Overrides:

doConnect0 in class AbstractEpollChannel

Throws:

Exception

setTcpMd5Sig

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

Throws:

IOException
