14.7 Connecting Functional Flow with Structural Flow Using Functional Flow Allocation

Flow between activities can either be control flow or object flow as described in Chapter 9, Section 9.5 and 9.6. The following sections address allocating object flow as represented on activity diagrams. Allocation of control flow may be depicted in a similar way as allocation of object flow. Flow allocation is typically an allocation of usage because items that flow between model elements are usually specified in the context of their usage.

14.7.1 Options for Functionally Allocating Flow

Item flows are used to depict flow between parts on internal block diagrams, as described in Chapter 7, Section 7.4. Item flows can have an associated item property. The ...
