apache_beam.typehints.native_type_compatibility module¶
Module to convert Python’s native typing types to Beam types.
-
apache_beam.typehints.native_type_compatibility.extract_optional_type(user_type)[source]¶ Extracts the non-None type from Optional type user_type.
If user_type is not Optional, returns None
-
apache_beam.typehints.native_type_compatibility.convert_to_beam_type(typ)[source]¶ Convert a given typing type to a Beam type.
Parameters: typ (typing.Union[type, str]) – typing type or string literal representing a type. Returns: The given type converted to a Beam type as far as we can do the conversion. Return type: type Raises: ValueError– The type was malformed.
-
apache_beam.typehints.native_type_compatibility.convert_to_beam_types(args)[source]¶ Convert the given list or dictionary of args to Beam types.
Parameters: - args – Either an iterable of types, or a dictionary where the values are
- types. –
Returns: If given an iterable, a list of converted types. If given a dictionary, a dictionary with the same keys, and values which have been converted.
-
apache_beam.typehints.native_type_compatibility.convert_to_typing_type(typ)[source]¶ Converts a given Beam type to a typing type.
This is the reverse of convert_to_beam_type.
Parameters: typ – If a typehints.TypeConstraint, the type to convert. Otherwise, typ will be unchanged. Returns: Converted version of typ, or unchanged. Raises: ValueError– The type was malformed or could not be converted.
-
apache_beam.typehints.native_type_compatibility.convert_to_typing_types(args)[source]¶ Convert the given list or dictionary of args to typing types.
Parameters: - args – Either an iterable of types, or a dictionary where the values are
- types. –
Returns: If given an iterable, a list of converted types. If given a dictionary, a dictionary with the same keys, and values which have been converted.
