IModelExporter Class

Base class for exporting data from an iModel.

@note Most uses cases will not require a custom subclass of IModelExporter. Instead, it is more typical to subclass/customize IModelExportHandler.

@see iModel Transformation and Data Exchange, registerHandler, IModelTransformer, IModelImporter
