The TaurusEmitterThread Class
==========================
This object get items from a python Queue and performs a thread safe operation on them.
It is useful to serialize Qt tasks in a background thread.
:param parent: a Qt/Taurus object
:param name: identifies object logs
:param queue: if None parent.getQueue() is used, if not then the queue passed as argument is used
:param method: the method to be executed using each queue item as argument
:param cursor: if True or QCursor a custom cursor is set while the Queue is not empty
How TaurusEmitterThread works
--------------------------
TaurusEmitterThread is a worker thread that processes a queue of iterables passed as arguments to the specified method every time that ``doSomething()`` is called:
* ``self.method(*item)`` will be called if TaurusEmitterThread.method has been initialized.
* ``item[0](item[1:])`` will be called if ``method`` is not initialized and the first element of the queued iterable is *callable*.
TaurusEmitterThread uses two queues:
* ``self.queue`` manages the objects added externally:
+ the ``next()`` method passes objects from ``self.queue`` to ``self.todo queue``
+ every time that a *somethingDone* signal arrives ``next()`` is called.
+ ``next()`` can be called also externally to ensure that the main queue is being processed.
+ the queue can be accessed externally using ``getQueue()``
+ ``getQueue().qsize()`` returns the number of remaining objects in queue.
+ while there are objects in queue the ``.next()`` method will override applications cursor. a call to ``next()`` with an empty queue will restore the original cursor.
* ``self.todo`` is managed by the ``run()/start()`` method:
- a loop waits continuously for new objects in ``self.todo`` queue.
- if an object is found, it is sent in a *doSomething* signal.
- if *"exit"* is found the loop exits.
