Detailed Description#

The earliestTime() , latestTime() , intervals() and isEmpty() methods are used to get information about the current time range.

The addInterval() , removeInterval() and clear() methods are used to modify the current time range.

When adding or removing intervals from the time range, existing intervals within the range may be expanded, trimmed, deleted, merged or split to ensure that all intervals within the time range remain distinct and disjoint. As a consequence, all intervals added or removed from a time range must be normal .

__init__(range)#
Parameters:

rangeQMediaTimeRange

Constructs a time range by copying another time range.

__init__(arg__1)
Parameters:

arg__1Interval

Constructs a time range that contains an initial interval, interval.

If interval is not normal , the resulting time range will be empty.

See also

addInterval()

__init__(start, end)
Parameters:
  • start – int

  • end – int

Constructs a time range that contains an initial interval from start to end inclusive.

If the interval is not normal , the resulting time range will be empty.

See also

addInterval()

__init__()

Constructs an empty time range.

addInterval(interval)#
Parameters:

intervalInterval

Adds the specified interval to the time range.

Adding intervals which are not normal is invalid, and will be ignored.

If the specified interval is adjacent to, or overlaps existing intervals within the time range, these intervals will be merged.

This operation takes linear time.

removeInterval()

addInterval(start, end)
Parameters:
  • start – int

  • end – int

This is an overloaded function.

Adds the interval specified by start and end to the time range.

See also

addInterval()

addTimeRange(arg__1)#
Parameters:

arg__1QMediaTimeRange

Adds each of the intervals in range to this time range.

Equivalent to calling addInterval() for each interval in range.

clear()#

Removes all intervals from the time range.

See also

removeInterval()

contains(time)#
Parameters:

time – int

Return type:

bool

Returns true if the specified time lies within the time range.

earliestTime()#
Return type:

int

Returns the earliest time within the time range.

For empty time ranges, this value is equal to zero.

See also

latestTime()

intervals()#
Return type:

.list of QMediaTimeRange.Interval

Returns the list of intervals covered by this time range.

isContinuous()#
Return type:

bool

Returns true if the time range consists of a continuous interval. That is, there is one or fewer disjoint intervals within the time range.

isEmpty()#
Return type:

bool

Returns true if there are no intervals within the time range.

See also

intervals()

latestTime()#
Return type:

int

Returns the latest time within the time range.

For empty time ranges, this value is equal to zero.

__ne__(rhs)#
Parameters:

rhsQMediaTimeRange

Return type:

bool

Returns true if one or more intervals in lhs are not present in rhs.

__add__(r2)#
Parameters:

r2QMediaTimeRange

Return type:

QMediaTimeRange

Returns a time range containing the union between r1 and r2.

__iadd__(arg__1)#
Parameters:

arg__1QMediaTimeRange

Return type:

QMediaTimeRange

Adds each interval in other to the time range and returns the result.

__iadd__(arg__1)
Parameters:

arg__1Interval

Return type:

QMediaTimeRange

Adds the specified interval to the time range and returns the result.

__sub__(r2)#
Parameters:

r2QMediaTimeRange

Return type:

QMediaTimeRange

Returns a time range containing r2 subtracted from r1.

__isub__(arg__1)#
Parameters:

arg__1QMediaTimeRange

Return type:

QMediaTimeRange

Removes each interval in other from the time range and returns the result.

__isub__(arg__1)
Parameters:

arg__1Interval

Return type:

QMediaTimeRange

Removes the specified interval from the time range and returns the result.

__eq__(rhs)#
Parameters:

rhsQMediaTimeRange

Return type:

bool

Returns true if all intervals in lhs are present in rhs.

removeInterval(interval)#
Parameters:

intervalInterval

Removes the specified interval from the time range.

Removing intervals which are not normal is invalid, and will be ignored.

Intervals within the time range will be trimmed, split or deleted such that no intervals within the time range include any part of the target interval.

This operation takes linear time.

addInterval()

removeInterval(start, end)
Parameters:
  • start – int

  • end – int

This is an overloaded function.

Removes the interval specified by start and end from the time range.

removeInterval()

removeTimeRange(arg__1)#
Parameters:

arg__1QMediaTimeRange

Removes each of the intervals in range from this time range.

Equivalent to calling removeInterval() for each interval in range.

swap(other)#
Parameters:

otherQMediaTimeRange

Swaps the current instance with the other.
