IfcPropertyDependencyRelationship Class

Syntax

C++

class IfcPropertyDependencyRelationship : public IfcResourceLevelRelationship;

Description

An IfcPropertyDependencyRelationship describes an identified dependency between the value of one property and that of another. The determination of value according to the dependency is required to be performed by an application that can then use the Expression attribute to flag the form of the dependency.
