Detailed Description

The base class for timeline components.

A CInterval represents a single action, event, or collection of nested intervals that will be performed at some specific time or over a period of time.

This is essentially similar to the Python "Interval" class, but it is implemented in C++ (hence the name). Intervals that may be implemented in C++ will inherit from this class; Intervals that must be implemented in Python will inherit from the similar Python class.

References _auto_pause, and INLINE.

void CInterval::set_manager ( CIntervalManager * manager ) [inline]

Explicitly sets the time within the interval.
Normally, you would use start() .. finish() to let the time play normally, but this may be used to set the time to some particular value.
Definition at line 80 of file cInterval.cxx.

void CInterval::set_wants_t_callback ( bool wants_t_callback ) [inline]

Changes the state of the 'wants_t_callback' flag.

void CInterval::setup_play ( double start_time,

double end_time,

double play_rate,

)

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.
