Constructor Details

LocalServerChannel

public LocalServerChannel()

Method Details

config

public ChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

localAddress

public LocalAddress 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

Overrides:

localAddress in class AbstractChannel

Returns:

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

remoteAddress

public LocalAddress 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

Overrides:

remoteAddress in class AbstractServerChannel

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.

isOpen

public boolean isOpen()

Description copied from interface: Channel

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

isActive

public boolean isActive()

Description copied from interface: Channel

Return true if the Channel is active and so connected.

isCompatible

protected boolean isCompatible(EventLoop loop)

Description copied from class: AbstractChannel

Return true if the given EventLoop is compatible with this instance.

Specified by:

isCompatible in class AbstractChannel

localAddress0

protected java.net.SocketAddress localAddress0()

Description copied from class: AbstractChannel

Returns the SocketAddress which is bound locally.

Specified by:

localAddress0 in class AbstractChannel

doRegister

protected void doRegister(ChannelPromise promise)

Description copied from class: AbstractChannel

Is called after the Channel is registered with its EventLoop as part of the register process. Subclasses may override this method

Overrides:

doRegister in class AbstractChannel

Parameters:

promise - ChannelPromise that must be notified once done to continue the registration.

doBind

protected void doBind(java.net.SocketAddress localAddress)
               throws java.lang.Exception

Description copied from class: AbstractChannel

Bind the Channel to the SocketAddress

Specified by:

doBind in class AbstractChannel

Throws:

java.lang.Exception

doClose

protected void doClose()
                throws java.lang.Exception

Description copied from class: AbstractChannel

Close the Channel

Specified by:

doClose in class AbstractChannel

Throws:

java.lang.Exception

doDeregister

protected void doDeregister()
                     throws java.lang.Exception

Description copied from class: AbstractChannel

Deregister the Channel from its EventLoop. Sub-classes may override this method

Overrides:

doDeregister in class AbstractChannel

Throws:

java.lang.Exception

doBeginRead

protected void doBeginRead()
                    throws java.lang.Exception

Description copied from class: AbstractChannel

Schedule a read operation.

Specified by:

doBeginRead in class AbstractChannel

Throws:

java.lang.Exception

serve

LocalChannel serve(LocalChannel peer)

readInbound

private void readInbound()

newLocalChannel

protected LocalChannel newLocalChannel(LocalChannel peer)

A factory method for LocalChannels. Users may override it to create custom instances of LocalChannels.

serve0

private void serve0(LocalChannel child)

newUnsafe

protected AbstractChannel.AbstractUnsafe newUnsafe()

Description copied from class: AbstractChannel

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

Overrides:
