# class pixeltable.iterators.StringSplitter Base class for Pixeltable iterators. ## method close() ```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}} close() -> None ``` Close the iterator and release all resources ## method create() ```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}} create(**kwargs: Any) -> tuple[type[ComponentIterator], dict[str, Any]] ``` ## method input\_schema() ```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}} input_schema( *args: Any, **kwargs: Any ) -> dict[str, pixeltable.type_system.ColumnType] ``` Provide the Pixeltable types of the init() parameters The keys need to match the names of the init() parameters. This is equivalent to the parameters\_types parameter of the @function decorator. ## method output\_schema() ```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}} output_schema( *args: Any, **kwargs: Any ) -> tuple[dict[str, pixeltable.type_system.ColumnType], list[str]] ``` Specify the dictionary returned by next() and a list of unstored column names **Returns:** * `tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]`: a dictionary which is turned into a list of columns in the output table a list of unstored column names ## method set\_pos() ```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}} set_pos(pos: int) -> None ``` Set the iterator position to pos
