Constructor Detail

OioSocketChannel

public OioSocketChannel()

Create a new instance with an new Socket

OioSocketChannel

public OioSocketChannel(java.net.Socket socket)

Create a new instance from the given Socket

Parameters:

socket - the Socket which is used by this instance

OioSocketChannel

public OioSocketChannel(Channel parent,
                        java.net.Socket socket)

Create a new instance from the given Socket

Parameters:

parent - the parent Channel which was used to create this instance. This can be null if the has no parent as it was created by your self.

socket - the Socket which is used by this instance

Method Detail

parent

public ServerSocketChannel parent()

Description copied from interface: Channel

Returns the parent of this channel.

Specified by:

parent in interface Channel

Specified by:

parent in interface SocketChannel

Overrides:

parent in class AbstractChannel

Returns:

the parent channel. null if this channel does not have a parent channel.

config

public OioSocketChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

Specified by:

config in interface SocketChannel

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

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 OioByteStreamChannel

isInputShutdown

public boolean isInputShutdown()

Description copied from interface: DuplexChannel

Returns true if and only if the remote peer shut down its output so that no more data is received from this channel. Note that the semantic of this method is different from that of Socket.shutdownInput() and Socket.isInputShutdown().

Specified by:

isInputShutdown in interface DuplexChannel

Overrides:

isInputShutdown in class AbstractOioByteChannel

isOutputShutdown

public boolean isOutputShutdown()

Specified by:

isOutputShutdown in interface DuplexChannel

See Also:

Socket.isOutputShutdown()

doShutdownOutput

@UnstableApi
protected final void doShutdownOutput()
                                            throws java.lang.Exception

Description copied from class: AbstractChannel

Called when conditions justify shutting down the output portion of the channel. This may happen if a write operation throws an exception.

Overrides:

doShutdownOutput in class AbstractChannel

Throws:

java.lang.Exception

shutdownOutput

public ChannelFuture shutdownOutput()

Specified by:

shutdownOutput in interface DuplexChannel

See Also:

Socket.shutdownOutput()

doReadBytes

protected int doReadBytes(ByteBuf buf)
                   throws java.lang.Exception

Description copied from class: AbstractOioByteChannel

Read bytes from the underlying Socket.

Overrides:

doReadBytes in class OioByteStreamChannel

Parameters:

buf - the ByteBuf into which the read bytes will be written

Returns:

amount the number of bytes read. This may return a negative amount if the underlying Socket was closed

Throws:

java.lang.Exception - is thrown if an error occurred

shutdownOutput

public ChannelFuture shutdownOutput(ChannelPromise promise)

Specified by:

shutdownOutput in interface DuplexChannel

See Also:

Will notify the given {@link ChannelPromise}

localAddress

public java.net.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 SocketChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

remoteAddress

public java.net.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 SocketChannel

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.

localAddress0

protected java.net.SocketAddress localAddress0()

Description copied from class: AbstractChannel

Returns the SocketAddress which is bound locally.

Specified by:

localAddress0 in class AbstractChannel

remoteAddress0

protected java.net.SocketAddress remoteAddress0()

Description copied from class: AbstractChannel
