FileDescriptor |
fd()
Returns the
FileDescriptor that is used by this Channel . |
protected Object |
filterOutboundMessage(Object msg)
Invoked when a new message is added to a
ChannelOutboundBuffer of this AbstractChannel , so that
the Channel implementation converts the message to another. |

newDirectBuffer(ByteBuf buf)
Returns an off-heap copy of the specified
ByteBuf , and releases the original one. |
protected ByteBuf |
newDirectBuffer(Object holder,
ByteBuf buf)
Returns an off-heap copy of the specified
ByteBuf , and releases the specified holder. |
protected io.netty.channel.epoll.AbstractEpollChannel.AbstractEpollUnsafe |
newUnsafe()
