IoUringServerSocketChannel

public IoUringServerSocketChannel()

Method Details

config

public ServerSocketChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

Specified by:

config in interface ServerSocketChannel

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 ServerSocketChannel

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 ServerSocketChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

doBind

public void doBind(SocketAddress localAddress)
            throws Exception

Description copied from class: AbstractChannel

Bind the Channel to the SocketAddress

Throws:

Exception

metadata

public final 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

doClose

protected final void doClose()
                      throws Exception

Description copied from class: AbstractChannel

Close the Channel

Throws:

Exception

newUnsafe

protected final io.netty.channel.uring.AbstractIoUringChannel.AbstractUringUnsafe 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 AbstractChannel

doWrite

protected final void doWrite(ChannelOutboundBuffer in)

Description copied from class: AbstractChannel

Flush the content of the given buffer to the remote peer.

cancelOutstandingReads

protected final void cancelOutstandingReads(IoRegistration registration,
 int numOutstandingReads)

Cancel all outstanding reads

Parameters:

registration - the IoRegistration.

numOutstandingReads - the number of outstanding reads, or -1 if multi-shot was used.

cancelOutstandingWrites

protected final void cancelOutstandingWrites(IoRegistration registration,
 int numOutstandingWrites)

Cancel all outstanding writes

Parameters:

registration - the IoRegistration.

numOutstandingWrites - the number of outstanding writes.

socketIsEmpty

protected boolean socketIsEmpty(int flags)

Return if the socket is guaranteed to be empty when the submitted io was executed and the completion event be created.

Parameters:

flags - the flags that were part of the completion

Returns:

true if empty.

nextOpsId

protected final short nextOpsId()

Returns the next id that should be used when submitting IoUringIoOps.

Returns:

opsId

isOpen

public final boolean isOpen()

Description copied from interface: Channel

Returns true if the Channel is open and may get active later

Specified by:
