Description
Methods
| Protected | class function IfcClassName: String; virtual; |
|
This item is declared in ancestor TIfcPersistent. Name for the IFC standard, used in IFC files. By default, this is just ClassName with prefix 'T' removed. | |
| Protected | function WantsGlobalId: Boolean; override; |
|
This item is declared in ancestor TIfcRoot. This item has no description. Showing description inherited from TIfcPersistent.WantsGlobalId.
If Strictly following the spec, this should be only defined for TIfcRoot, because only IfcRoot has GlobalId. In reality, we need GlobalId at TIfcPersistent to load some files, and we sometimes need Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 1656). | |

This item is declared in ancestor TIfcPersistent. Globally unique identifier for the object instance. Note: Not declared as TGUID, because TGUID cannot be published, but also we don't really need it: for our purposes, this identifier is just an arbitrary string. Note: IFC 4.3 specification puts this only at IfcRoot, not at every IFC class. But testcase https://github.com/buildingsmart-community/Community-Sample-Test-Files/blob/main/IFC%204.0.2.1%20(IFC%204)/ISO%20Spec%20archive/wall-with-opening-and-window.json (from IFC 4.0) shows this can be present at any IFC class, in particular TIfcGeometricRepresentationContext. In fact, TIfcGeometricRepresentationContext needs to have IFC JSON documentation says this, which seems to (unfortunately it is not unambiguous enough...) allow this at any IFC class: "Whereas the | |
