Orekit 13.1: getMinDate/getMaxDate no longer available in BoundedPropagator?

Orekit Python Wrapper usage
1

Hello everyone :slight_smile:

I am using the Python wrapper and I just upgraded the Orekit version from 13.0 to 13.1 and ran some tests.

I got:
AttributeError: ‘BoundedPropagator’ object has no attribute ‘getMinDate’

where the BoundedPropagator is obtained by calling

eph_generator.getGeneratedEphemeris()

I think the BoundedPropagator had the methods getMinDate/getMaxDate before, inherited from its parent class.

Was this change made on purpose? Because on the Orekit 13.1 (Java) documentation I see that the methods should be still inherited and available for the BoundedPropagator class.

Let me know if I am missing something.

Thank you very much in advance for your help, and for your work!

Hello @gnisi,

I suppose you are using the JCC Wrapper and not the JPype wrapper ? If so you must cast your generated ephemeris to access these methods as they are inherited from BoundedPVCoordinatesProvider in Orekit 13.1.

Hello @Vincent, and thank you very much for the solution!
Yes, I am using the JCC wrapper. I will cast it, thanks.
Regarding the wrappers: do we know if one or the other is planned to be maintained for longer?

Thanks,

Giacomo

Hello @gnisi,

I suggest you read this thread : Future of the Python wrappers - #2 by Serrof

In short, the JCC version will not be maintained in the future (this may be the last version depending on the major changes happening in 14.0).

Cheers,
Vincent
