Make NFDRS SWIG-wrapped Python objects picklable #42

Open wmjolly opened 3 years ago

wmjolly commented 3 years ago

"Pickling" allows Python to save the state of an object and restore it later. We need some sort of functionality like this to allow NFDRS calculations to be stopped and started again from the saved state. We call this "State Saving". I 'think' we could use Pickling in Python to do this but it can't Pickle a SWIG-wrapped object very well. When you get time, could you look into this?

"NFDRS has a 'State' variable that allows you to save the current model states. This allows you to calculate some indices, stop the calculations and then restart from where you left off."

This works in Python:

from nfdrs import NFDR2016Calc

nf= NFDR2016Calc()
nf.SaveState("state.bin");
nf.ReadState("state.bin");

That is perfect! Thanks for this.
