Method Details

config

public KQueueDomainDatagramChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

Specified by:

config in interface DomainDatagramChannel

Specified by:

config in class AbstractKQueueChannel

doBind

protected void doBind(SocketAddress localAddress)
               throws Exception

Description copied from class: AbstractChannel

Bind the Channel to the SocketAddress

Overrides:

doBind in class AbstractKQueueChannel

Throws:

Exception

doClose

protected void doClose()
                throws Exception

Description copied from class: AbstractChannel

Close the Channel

Overrides:

doClose in class AbstractKQueueChannel

Throws:

Exception

doConnect

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

Description copied from class: AbstractKQueueChannel

Connect to the remote peer

Overrides:

doConnect in class AbstractKQueueChannel

Throws:

Exception

doDisconnect

protected void doDisconnect()
                     throws Exception

Description copied from class: AbstractChannel

Disconnect this Channel from its remote peer

Overrides:

doDisconnect in class AbstractKQueueChannel

Throws:

Exception

doWriteMessage

protected boolean doWriteMessage(Object msg)
                          throws Exception

Specified by:

doWriteMessage in class AbstractKQueueDatagramChannel

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 AbstractChannel

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

Overrides:

isActive in class AbstractKQueueChannel

isConnected

public boolean isConnected()

Description copied from interface: DomainDatagramChannel

Return true if the DomainDatagramChannel is connected to the remote peer.

Specified by:

isConnected in interface DomainDatagramChannel

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 DomainDatagramChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

localAddress0

protected DomainSocketAddress localAddress0()

Description copied from class: AbstractChannel

Returns the SocketAddress which is bound locally.

Overrides:

localAddress0 in class AbstractKQueueChannel

newUnsafe

protected 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

Specified by:

newUnsafe in class AbstractKQueueChannel

peerCredentials

public PeerCredentials peerCredentials()
                                throws IOException

Returns the unix credentials (uid, gid, pid) of the peer SO_PEERCRED

Throws:

IOException

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 DomainDatagramChannel

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.

remoteAddress0

protected DomainSocketAddress remoteAddress0()

Description copied from class: AbstractChannel

Return the SocketAddress which the Channel is connected to.

Overrides:

remoteAddress0 in class AbstractKQueueChannel
