IModelTransformContext Interface @beta

The supported transformation context exposed by an IModelTransformer.

Use context to obtain this context. It records source-to-target mappings, accepts explicit mapping and geometry-filtering rules, and resolves transformed entities. Element cloning, database access, native resource management, and context persistence remain implementation details of the transformer.

Methods

Name Description
filterSubCategory(sourceSubCategoryId: string): void Exclude geometry belonging to a source SubCategory from cloned geometry streams.  
findTargetAspectId(sourceAspectId: string): string Find the target element aspect corresponding to a source element aspect.  
findTargetCodeSpecId(sourceCodeSpecId: string): string Find the target CodeSpec corresponding to a source CodeSpec.  
findTargetElementId(sourceElementId: string): string Find the target element corresponding to a source element.  
findTargetEntityId(sourceEntityId: | | | ): Promise< | | | > Find the target entity corresponding to a typed source entity reference.  
isSubCategoryFiltered(sourceSubCategoryId: string): boolean Determine whether a source SubCategory is currently filtered.  
remapCodeSpec(sourceCodeSpecName: string, targetCodeSpecName: string): void Add or replace a mapping from a source CodeSpec to a target CodeSpec.  
remapElement(sourceElementId: string, targetElementId: string): void Add or replace a mapping from a source element to a target element.  
remapElementAspect(sourceAspectId: string, targetAspectId: string): void Add or replace a mapping from a source element aspect to a target element aspect.  
remapElementClass(sourceClassFullName: string, targetClassFullName: string): void Add or replace a mapping from a source element class to a target element class.  
removeElement(sourceElementId: string): void Remove the mapping for a source element.  
removeElementAspect(sourceAspectId: string): void Remove the mapping for a source element aspect.  

Properties

Name Type Description
hasSubCategoryFilter Readonly boolean Whether any SubCategories are currently filtered.  
isBetweenIModels Readonly boolean Whether this context maps entities between two different iModels.
