Method Detail

createByteBuffer

protected void createByteBuffer(boolean force)

Allocate a ByteBuffer if the current instance is null;

updateAttachment

Description copied from class: WorkerThread

Updates Thread associated attachment according to the passed mode.

Specified by:

updateAttachment in class WorkerThread

Returns:

updated ThreadAttachment

Parameters:

t - the task to process

Throws:

Exception
