Method Details

channel

Channel channel()

fd

public FileDescriptor fd()

Description copied from interface: EpollIoHandle

Returns the FileDescriptor that used by this IoHandle.

Specified by:

fd in interface EpollIoHandle

Returns:

fd

close

public void close()

Description copied from interface: IoHandle

Called once the IoHandle should be closed. Even once this method is called this handle might still receive events via IoHandle.handle(IoRegistration, IoEvent) (if it was previous be registered and so its IoHandle.registered() method was called) until the IoHandle.unregistered() method is called.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface IoHandle

handle

public void handle(IoRegistration registration,
 IoEvent event)

Description copied from interface: IoHandle

Be called once there is something to handle.

Specified by:

handle in interface IoHandle

Parameters:

registration - the IoRegistration for this IoHandle.

event - the IoEvent that must be handled. The IoEvent is only valid while this method is executed and so must not escape it.

epollInReady

abstract void epollInReady()

Called once EPOLLIN event is ready to be processed

shouldStopReading

final boolean shouldStopReading(ChannelConfig config)

epollRdHupReady

final void epollRdHupReady()

Called once EPOLLRDHUP event is ready to be processed

clearEpollRdHup

private void clearEpollRdHup()

Clear the Native.EPOLLRDHUP flag from EPOLL, and close on failure.

shutdownInput

void shutdownInput(boolean allDataRead)

Shutdown the input side of the channel.

fireEventAndClose

private void fireEventAndClose(java.lang.Object evt)

recvBufAllocHandle

public EpollRecvByteAllocatorHandle recvBufAllocHandle()

Description copied from interface: Channel.Unsafe

Return the assigned RecvByteBufAllocator.Handle which will be used to allocate ByteBuf's when receiving data.

Specified by:

recvBufAllocHandle in interface Channel.Unsafe

Overrides:

recvBufAllocHandle in class AbstractChannel.AbstractUnsafe

newEpollHandle

EpollRecvByteAllocatorHandle newEpollHandle(RecvByteBufAllocator.ExtendedHandle handle)

Create a new EpollRecvByteAllocatorHandle instance.

Parameters:

handle - The handle to wrap with EPOLL specific logic.

flush0

protected final void flush0()

Overrides:

flush0 in class AbstractChannel.AbstractUnsafe

epollOutReady

final void epollOutReady()

Called once a EPOLLOUT event is ready to be processed

clearEpollIn0

protected final void clearEpollIn0()

connect

public void connect(java.net.SocketAddress remoteAddress,
 java.net.SocketAddress localAddress,
 ChannelPromise promise)

Description copied from interface: Channel.Unsafe

Connect the Channel of the given ChannelFuture with the given remote SocketAddress. If a specific local SocketAddress should be used it need to be given as argument. Otherwise just pass null to it. The ChannelPromise will get notified once the connect operation was complete.

Specified by:

connect in interface Channel.Unsafe

fulfillConnectPromise

private void fulfillConnectPromise(ChannelPromise promise,
 boolean wasActive)

fulfillConnectPromise

private void fulfillConnectPromise(ChannelPromise promise,
 java.lang.Throwable cause)

finishConnect

private void finishConnect()

doFinishConnect

private boolean doFinishConnect()
                         throws java.lang.Exception

Finish the connect

Throws:

java.lang.Exception
