Class TIfcActorRole

Unit

CastleIfc

Declaration

type TIfcActorRole = class(TIfcPersistent)

Description

This item has no description. Showing description inherited from TIfcPersistent.

Abstract class that can be serialized to / deserialized from an IFC file. This is not part of the official IFC standard, it is added for CGE purposes.

It is a TComponent, because all IFC classes are owned by a common owner. This way we avoid complicated memory management ("who is responsible for freeing who", or reference counting as we did for X3D nodes), and we can easily free all IFC classes by freeing the owner.
