Code Generation for Activity Diagram Object Flows

[DavidL]

I would like to generate java code for object flows in an activity diagram. Software for control flows works as expected. I can not figure out how to get software for the object flows.

For example, I would like to solve the following equation:

A=5
B=6
Out=i1+i2

I would like the sum to be reusable. I connect the object node for A to the pin with the name i1 and the object node B to the pin with the name i2.

In an ideal world, I would like to create data flows of control laws using a set of activities/actions for filters (lopass, hipass), math (sum, multiply) and so on. I would like to quickly connect the activities/actions together with object flows. I would then like to generate a complete software algorithm.

Is this possible? Does anyone have an example?
