evo.objects.typed.base.object_from_reference
object_from_reference(context: IContext, reference: ObjectReference | str) -> _BaseObject
Download a GeoscienceObject from an ObjectReference and create the appropriate typed instance.
This function downloads the object from a full ObjectReference (which can contain path, UUID, version, etc.) and automatically selects the correct typed class (e.g., PointSet, Regular3DGrid) based on the object's sub-classification.
Parameters:

Returns:

If no typed class is found for the object's sub-classification. Example:: from evo.objects.typed import object_from_reference from evo.objects import ObjectReference # Create reference from URL ref = ObjectReference("evo://org/workspace/object/b208a6c9-6881-4b97-b02d-acb5d81299bb") obj = await object_from_reference(context, ref) # obj will be a PointSet if the object is a pointset, # a Regular3DGrid if it's a regular-3d-grid, etc. |
