- addErrorForProperty() : void
- Creates a new validation error object for a property and adds it to the proper sub result of $this->result
- ensureFileUploadTypes() : void
- Ensures that the provided value is either an instance of UploadedFile or an ObjectStorage containing only UploadedFile instances.
- initializeDefaultOptions() : void
- Initialize default options.
- initializeTranslationOptions() : void
