TbIfcDescriptionCalculator.h

A special calculator that is used to reassign a set of values from one entity to another.

There are cases where properties or quantities are calculated by one entity, but assigned to another. This object describes an override in which a different entity is associated with the property set or quantity description. At this time, it is not possible to define a new type of this class externally. The class contains static utilities to obtain instances of the currently supported types of redirections.

Causes the calculation to be reassigned per the implementation of this particular redirection calculator.
