IfcWorkTime
IfcWorkTime
实体定义
IfcWorkTime定义了IfcWorkCalendar用于描述工作时间或非工作异常时间的时间段。除了开始和结束日期外，还可以通过各种类型的重复模式给出一组时间段。
工作时间应该有一个有意义的名称来描述时间段（例如，工作周、假日名称）。非周期性时间段应具有开始日期（IfcWorkTime.start）和结束日期（IfcWorkTime.finish）。在这种情况下，假设时间段从开始日期的0:00开始，到完成日期的24:00结束。
如果给定了重复模式（IfcWorkTime.RecurrencePattern），则开始和完成日期是可选的。然后，它们限制了无休止的重复模式。
