Actions are pieces of java code that are executed upon events in the process execution. The graph is an important
instrument in the communication about software requirements. But the graph is just one view (projection) of the
software being produced. It hides many technical details. Actions are a mechanism to add technical details outside
of the graphical representation. Once the graph is put in place, it can be decorated with actions. This means that
java code can be associated with the graph without changing the structure of the graph. The main event types are
entering a node, leaving a node and taking a transition. |
