Conversion details

Interaction Overview diagram

An Interaction Overview diagram is one of four types of Interaction diagrams. The other three are Timing, Sequence, and Communication diagrams.  An Interaction Overview diagram, just like an Activity diagram, visualizes a sequence of Activities. Most of the notation elements for the Interaction Overview diagram are the same as those for the Activity diagram, e.g., Initial, Decision, Fork, Join, and Final nodes. Interaction Occurrences and Interaction elements are two new elements in the Interaction Overview diagram.

After conversion, the Interaction Overview diagram will be placed within an Activity element.

Interaction element

Interaction elements display an inline Interaction diagram (Interaction Overview, Timing, Sequence, or Communication diagram). In EA, Interaction elements can be created to display more of other diagrams than those classified as Interaction diagrams.

Interaction Occurrence

Interaction Occurrence elements refer to an existing Interaction diagram. They are visually represented by a rectangular frame, which can be created by dragging the Interaction diagram from the project Browser to an Interaction Overview diagram and selecting the Interaction Occurrence option from the pop-up dialog.
