This example shows how to make an Extension Class "pickleable".
|
|
|
|
The world class below can be fully restored by passing the
|
|
appropriate argument to the constructor. Therefore it is sufficient
|
|
to define the pickle interface method __getinitargs__.
|
|
|
|
For more information refer to boost/libs/python/doc/pickle.html.
