KQueueDomainSocketChannel

public KQueueDomainSocketChannel()

Method Detail

newUnsafe

protected io.netty.channel.kqueue.AbstractKQueueChannel.AbstractKQueueUnsafe newUnsafe()

Description copied from class: AbstractChannel

Create a new AbstractChannel.AbstractUnsafe instance which will be used for the life-time of the Channel

Overrides:

newUnsafe in class AbstractKQueueStreamChannel

localAddress0

protected DomainSocketAddress localAddress0()

Description copied from class: AbstractChannel

Returns the SocketAddress which is bound locally.

Specified by:

localAddress0 in class AbstractChannel

remoteAddress0

protected DomainSocketAddress remoteAddress0()

Description copied from class: AbstractChannel

Return the SocketAddress which the Channel is connected to.

Specified by:

remoteAddress0 in class AbstractChannel

doBind

protected void doBind(SocketAddress localAddress)
               throws Exception

Description copied from class: AbstractChannel

Bind the Channel to the SocketAddress

Specified by:

doBind in class AbstractChannel

Throws:

Exception

config

public KQueueDomainSocketChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

Specified by:

config in interface DomainSocketChannel

doConnect

protected boolean doConnect(SocketAddress remoteAddress,
                            SocketAddress localAddress)
                     throws Exception

Description copied from class: AbstractKQueueStreamChannel

Connect to the remote peer

Overrides:

doConnect in class AbstractKQueueStreamChannel

Throws:

Exception

remoteAddress

public DomainSocketAddress 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 DomainSocketChannel

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 DomainSocketAddress 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 DomainSocketChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

doWriteSingle

protected boolean doWriteSingle(ChannelOutboundBuffer in,
                                int writeSpinCount)
                         throws Exception

Overrides:

doWriteSingle in class AbstractKQueueStreamChannel

Throws:

Exception

filterOutboundMessage

protected Object filterOutboundMessage(Object msg)

Description copied from class: AbstractChannel

Invoked when a new message is added to a ChannelOutboundBuffer of this AbstractChannel, so that the Channel implementation converts the message to another. (e.g. heap buffer -> direct buffer)

Overrides:

filterOutboundMessage in class AbstractKQueueStreamChannel

newDirectBuffer

protected final ByteBuf newDirectBuffer(ByteBuf buf)
