Method Detail

metadata

public io.netty.channel.ChannelMetadata metadata()

Specified by:

metadata in interface io.netty.channel.Channel

isCompatible

protected boolean isCompatible(io.netty.channel.EventLoop loop)

remoteAddress0

protected InetSocketAddress remoteAddress0()

Specified by:

remoteAddress0 in class io.netty.channel.AbstractChannel

newUnsafe

protected io.netty.channel.epoll.AbstractEpollChannel.AbstractEpollUnsafe newUnsafe()

doWrite

protected void doWrite(io.netty.channel.ChannelOutboundBuffer in)
                throws Exception

Specified by:

doWrite in class io.netty.channel.AbstractChannel

Throws:

Exception

filterOutboundMessage

protected Object filterOutboundMessage(Object msg)
                                throws Exception

Overrides:

filterOutboundMessage in class io.netty.channel.AbstractChannel

Throws:

Exception

fd

public final FileDescriptor fd()

Description copied from interface: UnixChannel

Returns the FileDescriptor that is used by this Channel.

Specified by:

fd in interface UnixChannel

config

public abstract EpollChannelConfig config()

Specified by:

config in interface io.netty.channel.Channel

isActive

public boolean isActive()

Specified by:

isActive in interface io.netty.channel.Channel

doClose

protected void doClose()
                throws Exception

Specified by:

doClose in class io.netty.channel.AbstractChannel

Throws:

Exception

shutdown

protected void shutdown(int fd)
                 throws IOException

Called on doClose() before the actual FileDescriptor is closed. This implementation does nothing.

Throws:

IOException

doDisconnect

protected void doDisconnect()
                     throws Exception

Specified by:

doDisconnect in class io.netty.channel.AbstractChannel

Throws:

Exception

isOpen

public boolean isOpen()

Specified by:

isOpen in interface io.netty.channel.Channel

doDeregister

protected void doDeregister()
                     throws Exception

Overrides:

doDeregister in class io.netty.channel.AbstractChannel

Throws:

Exception

doBeginRead

protected void doBeginRead()
                    throws Exception

Specified by:

doBeginRead in class io.netty.channel.AbstractChannel

Throws:

Exception

doRegister

Throws:

Exception

isInputShutdown0

protected final boolean isInputShutdown0()

newDirectBuffer

protected final io.netty.buffer.ByteBuf newDirectBuffer(io.netty.buffer.ByteBuf buf)

Returns an off-heap copy of the specified ByteBuf, and releases the original one.

newDirectBuffer

protected final io.netty.buffer.ByteBuf newDirectBuffer(Object holder,
                                      io.netty.buffer.ByteBuf buf)

Returns an off-heap copy of the specified ByteBuf, and releases the specified holder. The caller must ensure that the holder releases the original ByteBuf when the holder is released by this method.
