pyarrow.SerializationContext

class pyarrow.SerializationContext

Bases: object

__init__()

Initialize self. See help(type(self)) for accurate signature.

Methods

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 (TypeType) – 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).
