Field Detail

fast

public boolean fast

The undocumented attribute fast of the C version of cPickle disables memoization. Since having memoization on won't break anything, having this dummy setter for fast here won't break any code expecting it to do something. However without it code that sets fast fails(ie test_cpickle.py), so it's worth having.

persistent_id

public PyObject persistent_id

To write references to persistent objects, the persistent module must assign a method to persistent_id which returns either None or the persistent ID of the object. For the benefit of persistency modules written using pickle, it supports the notion of a reference to an object outside the pickled data stream. Such objects are referenced by a name, which is an arbitrary string of printable ASCII characters.

inst_persistent_id

public PyObject inst_persistent_id

Hmm, not documented, perhaps it shouldn't be public? XXX: fixme.
