                              boolean active)

Method Detail

newChildChannel

protected Channel newChildChannel(int fd,
                      byte[] addr,
                      int offset,
                      int len)
                           throws Exception

Throws:

Exception

localAddress0

protected DomainSocketAddress localAddress0()

Description copied from class: AbstractChannel

Returns the SocketAddress which is bound locally.

Specified by:

localAddress0 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

doClose

protected void doClose()
                throws Exception

Description copied from class: AbstractChannel

Close the Channel

Throws:

Exception

config

public EpollServerChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

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 ServerDomainSocketChannel

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 ServerDomainSocketChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

fd

public final Socket fd()

Description copied from interface: UnixChannel

Returns the FileDescriptor that is used by this Channel.

Specified by:

fd in interface UnixChannel

isActive

public boolean isActive()

Description copied from interface: Channel

Return true if the Channel is active and so connected.

Specified by:

isActive in interface Channel

doDisconnect

protected void doDisconnect()
                     throws Exception

Description copied from class: AbstractChannel

Disconnect this Channel from its remote peer

Specified by:

doDisconnect in class AbstractChannel

Throws:

Exception

isOpen

public boolean isOpen()

Description copied from interface: Channel

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

Specified by:

isOpen in interface Channel

doDeregister

protected void doDeregister()
                     throws Exception

Description copied from class: AbstractChannel

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

Overrides:

doDeregister in class AbstractChannel

Throws:

Exception

doBeginRead

protected final void doBeginRead()
                          throws Exception

Description copied from class: AbstractChannel

Schedule a read operation.

Specified by:

doBeginRead in class AbstractChannel

Throws:

Exception

doRegister

protected void doRegister()
                   throws Exception

Description copied from class: AbstractChannel

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

Overrides:

doRegister in class AbstractChannel

Throws:

Exception

newDirectBuffer

protected final ByteBuf newDirectBuffer(ByteBuf buf)

Returns an off-heap copy of the specified ByteBuf, and releases the original one.

newDirectBuffer

protected final ByteBuf newDirectBuffer(Object holder,
                      ByteBuf buf)

Returns an off-heap copy of the specified ByteBuf, and releases the specified holder. The caller must ensure that the holder releases the original ByteBuf when the holder is released by this method.

checkResolvable

protected static void checkResolvable(InetSocketAddress addr)

doReadBytes

protected final int doReadBytes(ByteBuf byteBuf)
                         throws Exception

Read bytes into the given ByteBuf and return the amount.

Throws:

Exception

doWriteBytes

protected final int doWriteBytes(ByteBuf buf,
               int writeSpinCount)
                          throws Exception
