Method Details

metadata

public ChannelMetadata metadata()

Description copied from interface: Channel

Return the ChannelMetadata of the Channel which describe the nature of the Channel.

Specified by:

metadata in interface Channel

Overrides:

metadata in class AbstractEpollChannel

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 AbstractEpollChannel

remoteAddress0

protected InetSocketAddress remoteAddress0()

Description copied from class: AbstractChannel

Return the SocketAddress which the Channel is connected to.

Overrides:

remoteAddress0 in class AbstractEpollChannel

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

Specified by:

newUnsafe in class AbstractEpollChannel

doWrite

protected void doWrite(ChannelOutboundBuffer in)
                throws Exception

Description copied from class: AbstractChannel

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 class AbstractEpollChannel

Throws:

Exception
