+ """This is what subclasses implement: yield all values from a
decoded profile package.
Find all values in the pes, and yield them decoded to a valid cls.input_value
format.
Should be a generator function, i.e. use 'yield' instead of
'return'.
- Usage example:
+ Yielded value must be a dict(). Usually, an implementation will return only
one key, like
- cls = esim.saip.personalization.Iccid
- # use a set() to get a list of unique values from all results
- vals = set( cls.get_values_from_pes(pes) )
- if len(vals) != 1:
- raise ValueError(f'{cls.name}: need exactly one value, got
{vals}')
- # the set contains a single value, return it
- return vals.pop()
+ { "ICCID": "1234567890123456789" }
+
+ Some implementations have more than one value to return, like
+
+ { "IMSI": "00101012345678", "IMSI-ACC" :
"5" }
Implementation example:
for pe in pes:
if my_condition(pe):
- yield b2h(my_bin_value_from(pe))
- '''
+ yield { cls.name: b2h(my_bin_value_from(pe)) }
