This function is called by the analyzer manager when a slot comes free either due to a timeout or due to a descent stop. In any case we need to start a new one here.

void SongSelectorLogic::step_reading_indices ( vector< Song * > * new_songs )

Executed as the response to an event posted by indexreader. The newsongs vector contains all the newly indexed songs. In return this function must contact the database which will actually add the songs to the full database, the cache if appropriate and the visualization collection if appropriate.

This version of the item list updater is used from within the index scanner It will not sort the data it retrieves from the database and will also not report on the lack of exiting songs at the moment. The history view is also not updated here.

void SongSelectorLogic::stop_reading_indices ( unsigned4 total )

Executed as the response to an event posted by the indexReader. It signals the finishing of reading the current index collection.

void SongSelectorLogic::timerTick ( ) [virtual, slot]

The timer thread will periodically call this function. Since it is the same thread it will be able to continue below. We don' want that because then we might have race conditions.

We can now check whether any button has been check to start an analyzer. We do this after the signal check because this function will also redraw the colors for the analyzer and will ensure an immediate color change when the text is updated in the signal checking round.
