Pickling of Java objects is restricted to classes that implement Serializable. Mixed pickle files containing both Java and Python objects are allowed. Only one copy of each Java object will appear in the pickle file even it is appears multiple times in the data structure. JPicklers and JUnpickler use Java ObjectOutputStream and ObjectInputStream to serialize objects. All of the usual Java serialization errors may be thrown. This is backed by the native cPickler implementation. Example: .. code-block:: python myobj = jpype.JClass('java.util.ArrayList')() myobj.add("test") from jpype.pickle import JPickler, JUnpickler with open("test.pic", "wb") as fd: JPickler(fd).dump(myobj) with open("test.pic", "rb") as fd: newobj = JUnpickler(fd).load() Proxies and other JPype specific module resources cannot be pickled currently. é)Úabsolute_importN)Údispatch_tableÚJPicklerÚ JUnpicklerc@seZdZdd„ZdS)Ú JUnserializercGs t d¡‚)Nz#Unpickling Java requires JUnpickler)ÚpickleÚUnpicklingError©ÚselfÚargs©r úI/home/ubuntu/sommelier/.venv/lib/python3.10/site-packages/jpype/pickle.pyÚ__call__Es zJUnserializer.__call__N©Ú__name__Ú __module__Ú __qualname__rr r r r rDs rc@s0eZdZdZdd„Zdd„Zdd„Zdd „Zd S) Ú _JDispatchzëDispatch for Java classes and objects.
