Constructor Detail

AbstractNioByteChannel

protected AbstractNioByteChannel(Channel parent,
                      SelectableChannel ch)

Create a new instance

Parameters:

parent - the parent Channel by which this instance was created. May be null

ch - the underlying SelectableChannel on which it operates

Method Detail

newUnsafe

protected AbstractNioChannel.AbstractNioUnsafe 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 AbstractChannel

doWrite

protected int doWrite(Object[] msgs,
          int msgsLength,
          int startIndex)
               throws Exception

Description copied from class: AbstractChannel

Flush the content of the given ByteBuf to the remote peer. Sub-classes may override this as this implementation will just thrown an UnsupportedOperationException

Specified by:

doWrite in class AbstractChannel

Returns:

the number of written messages

Throws:

Exception

doWriteFileRegion

protected abstract long doWriteFileRegion(FileRegion region,
                     boolean lastSpin)
                                   throws Exception

Write a FileRegion

Parameters:

region - the FileRegion from which the bytes should be written

lastSpin - true if this is the last write try

Returns:

amount the amount of written bytes

Throws:

Exception - thrown if an error accour

doReadBytes

protected abstract int doReadBytes(ByteBuf buf)
                            throws Exception

Read bytes into the given ByteBuf and return the amount.

Throws:

Exception

doWriteBytes

protected abstract int doWriteBytes(ByteBuf buf,
               boolean lastSpin)
                             throws Exception

Write bytes form the given ByteBuf to the underlying Channel.

Parameters:

buf - the ByteBuf from which the bytes should be written

lastSpin - true if this is the last write try

Returns:

amount the amount of written bytes

Throws:

Exception - thrown if an error accour

updateOpWrite

protected final void updateOpWrite(long expectedWrittenBytes,
                 long writtenBytes,
                 boolean lastSpin)
