Method Detail

createByteBuffer

protected void createByteBuffer(boolean force)

Allocate a ByteBuffer if the current instance is null;

updateAttachment

public ThreadAttachment updateAttachment(int mode)

Description copied from class: WorkerThread

Updates Thread associated attachment according to the passed mode.

Specified by:

updateAttachment in class WorkerThread

Returns:

updated ThreadAttachment

getAttachment

public ThreadAttachment getAttachment()

Description copied from class: WorkerThread

Specified by:

detach in class WorkerThread

Returns:

a new ThreadAttachment

attach

public void attach(ThreadAttachment threadAttachment)

Description copied from class: WorkerThread

Attach the ThreadAttachment to this instance. This will configure this Thread attributes like ByteBuffer, SSLEngine, etc.

Specified by:

attach in class WorkerThread

getByteBufferType

public ByteBufferFactory.ByteBufferType getByteBufferType()

Set the ByteBufferType to use when creating the ByteBuffer associated with this object.

Parameters:

byteBufferType - The ByteBuffer type.

processTask

protected void processTask(Callable t)
                    throws Exception

Processes the given task.

Parameters:

t - the task to process

Throws:

Exception

reset
