Working outside the classes¶

The software classes all provide the ‘Get’-method that allows extraction of an instance’s internal data.

transitions_s = transitions->Get()

transitions_dict = transitions->get()

This allows, for example, more control over the presentation of the data.

PLOT,transitions_s.data.frequency,1D5*transitions_s.data.intensity, $
     XTITLE=transitions_s.units.x.str, $
     YTITLE='integrated intensity [cm!U-2!N mol!U-1!N]', $
     PSYM=10

import matplotlib.pyplot as plt

plt.plot(transitions_dict['data']['frequency'], transitions_dict['data']['intensity'])
plt.xlabel(transitions_dict['units']['x']['str'])
plt.ylabel('integrated intensity [cm!U-2!N mol!U-1!N]')
plt.show()

Subsequently these data can be manipulated and even be set to the instancer, which will try altering its internal state to reflect that of the manipulated data.

transitions->Set,transitions_s

transitions.set(transitions_dict)

In addition, the ‘Set’-method accepts keywords to alter its internal state.

transitions->Set,Data=transitions_s.data

transitions.set(data=transitions_dict['data'])

Lastly, it is also possible to create new intances initialized with an appropriate data representation or through keywords.

transitions = OBJ_NEW('AmesPAHdbIDLSuite_Transitions', transitions_s)

transitions = OBJ_NEW('AmesPAHdbIDLSuite_Transitions', $
                       Type=transitions_s.type, $
                       Version=transitions_s.version, $
                       PAHdb=pahdb->Pointer(), $
                       Data=transitions_s.data, $
                       Uids=transitions_s.uids, $
                       Model=transitions_s.model, $
                       Units=transitions_s.units)

transitions = transitions(transitions_dict)

transitions = trantions(type=transitions_dict['type'], \
                        version=transitions_dict['version'], \
                        pahdb=pahdb, \
                        data=transitions_dict['data'], \
                        uids=transitions_dict['uids'], \
                        model=transitions_dict['model'], \
                        units=transitions_dict['units'])
