TimeRangeCollection class

The TimeRangeCollection utility class abstracts the notion of an ordered collection of TimeRange specifications and provides services to translate itself into a Metadata instance.
public final class TimeRangeCollection { 
    public static const MARK_RANGES:String = "mark_ranges"; 
  
    public function TimeRangeCollection(timeRanges:Vector.<TimeRange>) {…} 
    public function addTimeRange(timeRange:TimeRange):void {…} 
    public function toMetadata(options:Metadata):Metadata {…} 
}

The defined value for the type of collection are MARK_RANGES , DELETE_RANGES , and REPLACE_RANGES . You can create TimeRangeCollection s using these three types.
