This also required that empty blocks be generated in case the
developer wanted to add code only after generation.
Other Notable Language Constructs Later, the language speci?¬?cation was
extended by customer request to allow an optional naming policy. This was suggested
to allow modelers to give human-readable function names that are visible in the
generated Python code. The function name property was added to the modeling
concepts and its use was made optional and left to the modeler??™s discretion; if not
given in the model, unique function names are generated, minimizing the
modeling work.
The speci?¬?cation of navigation ?¬‚ow required ways to specify application start and
end. For this purpose, Start and Stop concepts similar to state machines were added to
the language. As not all applications are necessarily closed during user navigation, the
Stop element was extended to choose a policy for closing the application. Application
exit was set as the default choice but the Stop element allowed choosing a wait policy.
The wait policy is typical for applications that have several views and ending the
navigation in one view should not close the whole application but allow for choices in
other views or external processes that have been called, for example, via the Start
exe concept.
All possible Python framework services, such as retrieving phone location
information from the network, accessing drives of the phone, or copying ?¬?les, were
not included in the language as their own concepts.
