Type definition

IfcBenchmarkEnum is an enumeration used to identify the logical comparators that can be applied in conjunction with constraint values.

HISTORY  New enumeration in IFC2.0

IFC4 CHANGE  Extended to include comparators for item-set and set-item comparisons: INCLUDES, NOTINCLUDES, INCLUDEDIN and NOTINCLUDEDIN, to test if an individual item is a member of a given aggregation, or if an aggregation has a given individual item as a member.
