class
pyarrow.SerializationContext¶ Bases:
pyarrow.lib._Weakrefable-
__init__(*args, **kwargs)¶ Initialize self. See help(type(self)) for accurate signature.
Methods
__init__(*args, **kwargs)Initialize self.
clone(self)Return copy of this SerializationContext.
deserialize(self, what)Call pyarrow.deserialize and pass this SerializationContext.
deserialize_components(self, what)Call pyarrow.deserialize_components and pass this SerializationContext.
register_type(self, type_, type_id[, …])EXPERIMENTAL: Add type to the list of types we can serialize.
serialize(self, obj)Call pyarrow.serialize and pass this SerializationContext.
serialize_to(self, value, sink)Call pyarrow.serialize_to and pass this SerializationContext.
set_pickle(self, serializer, deserializer)Set the serializer and deserializer to use for objects that are to be pickled.
-
clone(self)¶ Return copy of this SerializationContext.
- Returns
clone (SerializationContext)
-
deserialize(self, what)¶ Call pyarrow.deserialize and pass this SerializationContext.
-
deserialize_components(self, what)¶ Call pyarrow.deserialize_components and pass this SerializationContext.
-
register_type(self, type_, type_id, pickle=False, custom_serializer=None, custom_deserializer=None)¶ EXPERIMENTAL: Add type to the list of types we can serialize.
- Parameters
type_ (type) – The type that we can serialize.
type_id (string) – A string used to identify the type.
pickle (bool) – True if the serialization should be done with pickle. False if it should be done efficiently with Arrow.
custom_serializer (callable) – This argument is optional, but can be provided to serialize objects of the class in a particular way.
custom_deserializer (callable) – This argument is optional, but can be provided to deserialize objects of the class in a particular way.
-
serialize(self, obj)¶ Call pyarrow.serialize and pass this SerializationContext.
-
serialize_to(self, value, sink)¶ Call pyarrow.serialize_to and pass this SerializationContext.
-
set_pickle(self, serializer, deserializer)¶ Set the serializer and deserializer to use for objects that are to be pickled.
- Parameters
serializer (callable) – The serializer to use (e.g., pickle.dumps or cloudpickle.dumps).
deserializer (callable) – The deserializer to use (e.g., pickle.dumps or cloudpickle.dumps).
