This is an interesting question...
Ptolemy II supports model mutations during execution, so it is
certainly possible to do this. However, there is no built-in
infrastructure that does it. You could write Java code in
an actor that does it... Ideally, you could construct
a ChangeRequest and queue that with any object in the hierarchy.
But I'm not sure this will yield the timing you require.
We are currently investigating implementations of higher-order
functions, which would behave in a similar way, constructing
submodels on the fly. However, there is nothing released yet.
If you are coming to the miniconference next week, you might
want to talk to Jorn Janneck and Xiaojun Liu about this issue.
