Method Detail

isInputShutdown

protected boolean isInputShutdown()

metadata

public ChannelMetadata metadata()

Description copied from interface: Channel

Return the ChannelMetadata of the Channel which describe the nature of the Channel.

checkInputShutdown

protected boolean checkInputShutdown()

Check if the input was shutdown and if so return true. The default implementation sleeps also for AbstractOioChannel.SO_TIMEOUT milliseconds to simulate some blocking.

doRead

protected void doRead()

Specified by:

doRead in class AbstractOioChannel

doWrite

protected void doWrite(ChannelOutboundBuffer in)
                throws java.lang.Exception

Description copied from class: AbstractChannel

Flush the content of the given buffer to the remote peer.

Specified by:

doWrite in class AbstractChannel

Throws:

java.lang.Exception

filterOutboundMessage

protected final java.lang.Object filterOutboundMessage(java.lang.Object msg)
                                                throws java.lang.Exception

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

Throws:

java.lang.Exception

available

protected abstract int available()

Return the number of bytes ready to read from the underlying Socket.

doReadBytes

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

Read bytes from the underlying Socket.

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

doWriteBytes

protected abstract void doWriteBytes(ByteBuf buf)
                              throws java.lang.Exception

Write the data which is hold by the ByteBuf to the underlying Socket.

Parameters:

buf - the ByteBuf which holds the data to transfer

Throws:

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

doWriteFileRegion

protected abstract void doWriteFileRegion(FileRegion region)
                                   throws java.lang.Exception

Write the data which is hold by the FileRegion to the underlying Socket.

Parameters:

region - the FileRegion which holds the data to transfer

Throws:

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