IfcBenchmarkEnum

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.

Enumeration definition

Constant	Description
GREATERTHAN	Identifies that a value must be greater than that set by the constraint.
GREATERTHANOREQUALTO	Identifies that a value must be either greater than or equal to that set by the constraint.
LESSTHAN	Identifies that a value must be less than that set by the constraint.
LESSTHANOREQUALTO	Identifies that a value must be either less than or equal to that set by the constraint.
EQUALTO	Identifies that a value must be equal to that set by the constraint.
NOTEQUALTO	Identifies that a value must be not equal to that set by the constraint.
INCLUDES	Identifies that an aggregation (set, list or table) must include the value (individual item) set by the constraint.
NOTINCLUDES	Identifies that an aggregation (set, list or table) must not include the value (individual item) set by the constraint.
INCLUDEDIN	Identifies that a value (individual item) must be included in the aggregation (set, list or table) set by the constraint.
NOTINCLUDEDIN	Identifies that a value (individual item) must not be included in the aggregation (set, list or table) set by the constraint.
