Constructor Detail

OioByteStreamChannel

protected OioByteStreamChannel(Channel parent)

Create a new instance

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.

Method Detail

activate

protected final void activate(InputStream is,
                              OutputStream os)

Activate this instance. After this call isActive() will return true.

isActive

public boolean isActive()

Description copied from interface: Channel

Return true if the Channel is active and so connected.

available

protected int available()

Description copied from class: AbstractOioByteChannel

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

Specified by:

available in class AbstractOioByteChannel

doReadBytes

protected int doReadBytes(ByteBuf buf)
                   throws Exception

Description copied from class: AbstractOioByteChannel

Read bytes from the underlying Socket.

Specified by:

doReadBytes in class AbstractOioByteChannel

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:

Exception - is thrown if an error occurred

doWriteBytes

protected void doWriteBytes(ByteBuf buf)
                     throws Exception

Description copied from class: AbstractOioByteChannel

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

Specified by:

doWriteBytes in class AbstractOioByteChannel

Parameters:

buf - the ByteBuf which holds the data to transfer

Throws:

Exception - is thrown if an error occurred

doWriteFileRegion

protected void doWriteFileRegion(FileRegion region)
                          throws Exception

Description copied from class: AbstractOioByteChannel

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

Specified by:

doWriteFileRegion in class AbstractOioByteChannel

Parameters:

region - the FileRegion which holds the data to transfer

Throws:

Exception - is thrown if an error occurred

doClose

protected void doClose()
                throws Exception

Description copied from class: AbstractChannel

Close the Channel

Specified by:

doClose in class AbstractChannel

Throws:

Exception
