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。

IfcWorkTime
4	RecurrencePattern	IfcRecurrencePattern	[0:1]	Recurrence pattern that defines a time period, which, if given, is valid within the time period defined by IfcWorkTime.Start and IfcWorkTime.Finish.	X
5	Start	IfcDate	[0:1]	Start date of the work time (0:00), that might be further restricted by a recurrence pattern.	X
6	Finish	IfcDate	[0:1]	End date of the work time (24:00), that might be further restricted by a recurrence pattern.	X
