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

Constructs an empty time range.
Constructs a time range that contains an initial interval, interval .
若 interval 不是 normal , the resulting time range will be empty.

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

()
析構函數。
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.
另請參閱 removeInterval ().
這是重載函數。
Adds the interval specified by start and end to the time range.
另請參閱 addInterval ().
Adds each of the intervals in range to this time range.
相當於調用 addInterval () for each interval in range .
Removes all intervals from the time range.
另請參閱 removeInterval ().
返迴 true 若指定 time lies within the time range.
Returns the earliest time within the time range.
For empty time ranges, this value is equal to zero.
另請參閱 latestTime ().
Returns the list of intervals covered by this time range.
Returns true if the time range consists of a continuous interval. That is, there is one or fewer disjoint intervals within the time range.
Returns true if there are no intervals within the time range.
另請參閱 intervals ().
Returns the latest time within the time range.
For empty time ranges, this value is equal to zero.
另請參閱 earliestTime ().
移除指定 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.
另請參閱 addInterval ().
這是重載函數。
Removes the interval specified by start and end from the time range.
另請參閱 removeInterval ().
Removes each of the intervals in range from this time range.
相當於調用 removeInterval () for each interval in range .

swap
(

Adds each interval in other to the time range and returns the result.
Adds the specified interval to the time range and returns the result.
Removes each interval in other from the time range and returns the result.
移除指定 interval from the time range and returns the result.

Takes a copy of the other time range and returns itself.
Sets the time range to a single continuous interval, interval .
Returns true if one or more intervals in lhs are not present in rhs .
Returns a time range containing the union between r1 and r2 .
Returns a time range containing r2 減去 r1 .
Returns true if all intervals in lhs are present in rhs .
