A class can pickle itself like this:
class foo(object):
#lots of code here
def _loadPickle(self, fileName):
'''Load data from a file in pickle format.'''
f = open(fileName, 'rb')
newStore = cPickle.load(f)
self.__dict__ = newStore.__dict__ #copy the data attributes
f.close()
def _savePickle(self, fileName):
'''Dump the data into a binary pickle file'''
f = open(fileName, 'wb')
cPickle.dump(self, f, 2)
f.close()
Kind regards,
Eike.
