It's recommended to set this parameter to ``False`` when your code does not rely on two objects having the same ``id()`` value, and when it is sufficient for those two objects to be equal by ``==``, such as when serializing sklearn instances. If you experience (de)serialization being incorrect when you use numpy, pandas, or sklearn handlers, this should be set to ``False``. If you want the output to not include the dtype for numpy arrays, add:: jsonpickle.register( numpy.generic, UnpicklableNumpyGenericHandler, base=True ) before your pickling code. :param make_refs: If set to False jsonpickle's referencing support is disabled. Objects that are id()-identical won't be preserved across encode()/decode(), but the resulting JSON stream will be conceptually simpler. jsonpickle detects cyclical objects and will break the cycle by calling repr() instead of recursing when make_refs is set False. :param keys: If set to True then jsonpickle will encode non-string dictionary keys instead of coercing them into strings via `repr()`. This is typically what you want if you need to support Integer or objects as dictionary keys. :param max_depth: If set to a non-negative integer then jsonpickle will not recurse deeper than 'max_depth' steps into the object. Anything deeper than 'max_depth' is represented using a Python repr() of the object. :param reset: Custom pickle handlers that use the `Pickler.flatten` method or `jsonpickle.encode` function must call `encode` with `reset=False` in order to retain object references during pickling. This flag is not typically used outside of a custom handler or `__getstate__` implementation. :param backend: If set to an instance of jsonpickle.backend.JSONBackend, jsonpickle will use that backend for deserialization. :param warn: If set to True then jsonpickle will warn when it returns None for an object which it cannot pickle (e.g. file descriptors). :param context: Supply a pre-built Pickler or Unpickler object to the `jsonpickle.encode` and `jsonpickle.decode` machinery instead of creating a new instance. The `context` represents the currently active Pickler and Unpickler objects when custom handlers are invoked by jsonpickle. :param max_iter: If set to a non-negative integer then jsonpickle will consume at most `max_iter` items when pickling iterators. :param use_decimal: If set to True jsonpickle will allow Decimal instances to pass-through, with the assumption that the simplejson backend will be used in `use_decimal` mode. In order to use this mode you will need to configure simplejson:: jsonpickle.set_encoder_options('simplejson', use_decimal=True, sort_keys=True) jsonpickle.set_decoder_options('simplejson', use_decimal=True) jsonpickle.set_preferred_backend('simplejson') NOTE: A side-effect of the above settings is that float values will be converted to Decimal when converting to json. :param numeric_keys: Only use this option if the backend supports integer dict keys natively. This flag tells jsonpickle to leave numeric keys as-is rather than conforming them to json-friendly strings. Using ``keys=True`` is the typical solution for integer keys, so only use this if you have a specific use case where you want to allow the backend to handle serialization of numeric dict keys. :param use_base85: If possible, use base85 to encode binary data. Base85 bloats binary data by 1/4 as opposed to base64, which expands it by 1/3. This argument is ignored on Python 2 because it doesn't support it. :param fail_safe: If set to a function exceptions are ignored when pickling and if a exception happens the function is called and the return value is used as the value for the object that caused the error :param indent: When `indent` is a non-negative integer, then JSON array elements and object members will be pretty-printed with that indent level. An indent level of 0 will only insert newlines. ``None`` is the most compact representation. Since the default item separator is ``(', ', ': ')``, the output might include trailing whitespace when ``indent`` is specified. You can use ``separators=(',', ': ')`` to avoid this. This value is passed directly to the active JSON backend library and not used by jsonpickle directly. :param separators: If ``separators`` is an ``(item_separator, dict_separator)`` tuple then it will be used instead of the default ``(', ', ': ')`` separators. ``(',', ':')`` is the most compact JSON representation. This value is passed directly to the active JSON backend library and not used by jsonpickle directly. :param include_properties: Include the names and values of class properties in the generated json. Properties are unpickled properly regardless of this setting, this is meant to be used if processing the json outside of Python. Certain types such as sets will not pickle due to not having a native-json equivalent. Defaults to ``False``. :param handle_readonly: Handle objects with readonly methods, such as Django's SafeString. This basically prevents jsonpickle from raising an exception for such objects. You MUST set ``handle_readonly=True`` for the decoding if you encode with this flag set to ``True``. >>> encode('my string') == '"my string"' True >>> encode(36) == '36' True >>> encode({'foo': True}) == '{"foo": true}' True >>> encode({'foo': [1, 2, [3, 4]]}, max_depth=1) '{"foo": "[1, 2, [3, 4]]"}' z-keys will default to True in jsonpickle 5.0.0) stacklevelz@numeric_keys is deprecated, use keys=True (will remove in 5.0.0)zAuse_decimal is deprecated and will be removed in jsonpickle 5.0.0) unpicklable make_refskeysbackend max_depthwarnmax_iter numeric_keys use_decimal use_base85 fail_safeinclude_propertieshandle_readonlyoriginal_object)reset)indent separators)warningsrDeprecationWarningr Picklerencodeflatten)valuer rrrrrrcontextrrrrrrrrrs ?/DATA/.local/lib/python3.12/site-packages/jsonpickle/pickler.pyr!r!sD MM?"
