4.7.1.1 Step 1 ­­ generate the bindings
We generate code with the following command line:
$ generateDS.py ­f \
­o member_specs_api.py \
­s member_specs_upper.py \
­­super=member_specs_api \
­­member­specs=list \
member_specs.xsd
Notes:
●
●
We generate the member specifications as a list with the command line option ­­member­specs=list.
We generate an "application" module with the ­s command line option. We'll put
our application specific code in member_specs_upper.py.
4.7.1.2 Step 2 ­­ add application­specific code
And, here is the subclass file (member_specs_upper.py, generated with the "­s" command line option), to which we have added a bit of code that converts any string­type
members to upper case. You can think of this module as a special "application" of the generated classes.
