int CMetaInterval::add_c_interval (  CInterval *  c_interval,
double  rel_time,
RelativeStart  rel_to
) 
 

Adds a new CInterval to the list.

The interval will be played when the indicated time (relative to the given point) has been reached.

The return value is the index of the def entry representing the new interval.

int CMetaInterval::add_ext_index (  int  ext_index,
const string &  name,
double  duration,
bool  open_ended,
double  rel_time,
RelativeStart  rel_to
) 
 

Adds a new external interval to the list.

This represents some object in the external scripting language that has properties similar to a CInterval (for instance, a Python Interval object).

The CMetaInterval object cannot play this external interval directly, but it records a placeholder for it and will ask the scripting language to play it when it is time, via is_event_ready() and related methods.

The ext_index number itself is simply a handle that the scripting language makes up and associates with its interval object somehow. The CMetaInterval object does not attempt to interpret this value.

The return value is the index of the def entry representing the new interval.

)  [private]
 

Process a single event in the interval, moving forwards in time.

Process a single event in the interval, moving backwards in time.

This undoes the indicated event. If the event represents a new begin, adds it to the new_active list; if it is an end, finalizes it.

void CMetaInterval::enqueue_event (  int  n,

Enqueues the indicated interval for invocation after we have finished scanning for events that need processing this frame.

is_initial is only relevant for event types ET_instant or ET_reverse_instant, and indicates whether we are in the priv_initialize() (or priv_reverse_initialize()) call, and should therefore only invoke open-ended intervals.

time is only relevant for ET_initialize, ET_reverse_initialize, and ET_step.

Called to prepare the interval for automatic timed playback, e.g.

via a Python task. The interval will be played from start_t to end_t, at a time factor specified by play_rate. start_t must always be less than end_t (except for the exception for end_t == -1, below), but if play_rate is negative the interval will be played backwards.
