UML 2.0 Elements for Activity Diagrams
Following are elements for the activity diagram as defined by UML 2.0:
- Activity Invocation: This is the new name for the activity element.
It has an additional property called multiplicity.
- Fork/Join nodes: The fork/join nodes have been replaced with synchronization
bars.
- Initial Node: Formerly known as the start state element. Use initial
node to indicate the initial state in an activity diagram.
- Activity Final: Formerly known as the end state element. Use activity
final to indicate the final state in an activity diagram.
- Flow Final: Use the flow final element from a decision element. Designates
either the termination or merge of a flow.
- Activity Partition: This is the new name for the swimlane element.
- Signal: Signal sending and receipt elements have been removed from
the toolbar. To designate a signal sending element, drop an object onto the
diagram, and set the stereotype property as "Signal" through the
Properties view of the object.
- Time Signal: A stereotype property for an object. To designate a
time signal element, drop an object onto the diagram, and set the stereotype
property as "Time Signal" through the Properties view of the object.
- Multiplicity: Set the multiplicity of an activity element through
its Properties view. Multiplicity displays in the upper right-hand corner
of the activity.
- Control Flow Link: Formerly known as the transition link. Use the
control flow link between state elements on an activity diagram.
- Synchronous and Asynchronous input/output: Specify as text on flow
links, for example, {sync} or {async}.
- Interruptible Activity Region: Use this type of grouping to encapsulate
activity and decision elements that constitute loops in a process.
- Iteration Activity Group: Use an iteration group to set apart a loop
in the flow of an activity.
- Interrupting Edge: Use an interrupting edge to show a non-local termination
of flow.
NB: By default, Together uses the UML 1.4 specification for modeling
diagrams. To enable UML 2.0 support, see Enabling UML
2.0 Features.
