|
|
* nsSMILTimeValue class
|
|
*
|
|
* A tri-state time value.
|
|
*
|
|
* First a quick overview of the SMIL time data types:
|
|
*
|
|
* nsSMILTime -- a timestamp in milliseconds.
|
|
* nsSMILTimeValue -- (this class) a timestamp that can take the additional
|
|
* states 'indefinite' and 'unresolved'
|
|
* nsSMILInstanceTime -- an nsSMILTimeValue used for constructing intervals. It
|
|
* contains additional fields to govern reset behavior
|
|
* and track timing dependencies (e.g. syncbase timing).
|
|
* nsSMILInterval -- a pair of nsSMILInstanceTimes that defines a begin and
|
|
* an end time for animation.
|
|
* nsSMILTimeValueSpec -- a component of a begin or end attribute, such as the
|
|
* '5s' or 'a.end+2m' in begin="5s; a.end+2m". Acts as
|
|
* a broker between an nsSMILTimedElement and its
|
|
* nsSMILInstanceTimes by generating new instance times
|
|
* and handling changes to existing times.
|
|
*
|
|
* Objects of this class may be in one of three states:
|
|
*
|
|
* 1) The time is resolved and has a definite millisecond value
|
|
* 2) The time is resolved and indefinite
|
|
* 3) The time is unresolved
|
|
*
|
|
* In summary:
|
|
*
|
|
* State | GetMillis | IsDefinite | IsIndefinite | IsResolved
|
|
* -----------+-----------------+------------+--------------+------------
|
|
* Definite | nsSMILTimeValue | true | false | true
|
|
* -----------+-----------------+------------+--------------+------------
|
|
* Indefinite | -- | false | true | true
|
|
* -----------+-----------------+------------+--------------+------------
|
|
* Unresolved | -- | false | false | false
