Interval Structstruct QMediaTimeRange::Interval
The QMediaTimeRange::Interval class represents a time interval with integer precision. More...
|Interval(qint64 start, qint64 end)|
|bool||contains(qint64 time) const|
|Interval||translated(qint64 offset) const|
|bool||operator!=(Interval lhs, Interval rhs)|
|bool||operator==(Interval lhs, Interval rhs)|
An interval is specified by an inclusive start() and end() time. These must be set in the constructor, as this is an immutable class. The specific units of time represented by the class have not been defined - it is suitable for any times which can be represented by a signed 64 bit integer.
The isNormal() method determines if a time interval is normal (a normal time interval has start() <= end()). A normal interval can be received from an abnormal interval by calling the normalized() method.
The contains() method determines if a specified time lies within the time interval.
The translated() method returns a time interval which has been translated forwards or backwards through time by a specified offset.

Member Function Documentation
Interval::Interval(qint64 start, qint64 end)
Constructs an interval with the specified start and end times.
bool Interval::contains(qint64 time) const
Returns true if the time interval contains the specified time. That is, start() <= time <= end().
qint64 Interval::end() const
Returns the end time of the interval.
See also start().
bool Interval::isNormal() const
Returns true if this time interval is normal. A normal time interval has start() <= end().
See also normalized().
Interval Interval::normalized() const
Returns a normalized version of this interval.
If the start() time of the interval is greater than the end() time, then the returned interval has the start and end times swapped.
qint64 Interval::start() const
Returns the start time of the interval.
See also end().
Interval Interval::translated(qint64 offset) const
Returns a copy of this time interval, translated by a value of offset. An interval can be moved forward through time with a positive offset, or backward through time with a negative offset.
