Properties of elements on UML activity diagrams
For the latest documentation on Visual Studio 2017, see Visual Studio 2017 Documentation.
On a UML activity diagram, each element on the diagram has properties. To see the properties of an element, right-click the element on the diagram or in UML Model Explorer and then click Properties. The properties appear in the Properties window.
This topic is about the properties of elements on UML activity diagrams. For information about how to read UML activity diagrams, see UML Activity Diagrams: Reference. For more information about how to draw UML activity diagrams, see UML Activity Diagrams: Guidelines.
|Name||A default name||All||Identifies the element.|
|Qualified Name||Package :: Name||All||Identifies the element uniquely. Prefixed with the qualified name of the package that contains it.|
|Work Items||0 associated||All||The number of work items associated with this element. To associate work items, see Link model elements and work items.|
|Description||(none)||All||You can make general notes about the element here.|
|Color||(default for the type)||All||The color of the shape.|
|Body||(none)||Action||Specifies the action in detail.|
|Language||(none)||Action||The language of the expression in Body.|
|Local Postconditions||(none)||Action, Send, Accept, Call Behavior, Call Operation||Constraints that must be satisfied when execution ends. The goal achieved by the action.|
|Local Preconditions||(none)||Action, Send, Accept, Call Behavior, Call Operation||Constraints that must be satisfied before execution begins.|
|Is Synchronous||True||Call Behavior, Call Operation||- If true, the action waits until the activity terminates.|
|Behavior||(none)||Call Behavior||- The activity invoked.|
|Operation||(none)||Call Operation||- The operation invoked.|
|Is Unmarshall||False||Accept Event||- If true, there can be several typed output pins, and data is unmarshaled onto them. If false, all data appear on one pin.|
|Upper Bound||*||Object Node, Activity Parameter||0 indicates that data must pass directly along the flow.|
* indicates that data can be stored in the flow.
|Selection||(none)||Object Node, Activity Parameter, Input Pin, Output Pin, Object Flow||Invokes a process that filters the data. This process can be defined in another diagram.|
|Ordering||(none)||Object Node, Activity Parameter, Input Pin, Output Pin||- How multiple tokens are stored.|
|Is Control||False||Input Pin, Output Pin||- If true, the flow on this pin is a control flow. If false, it is an object flow.|
|Type||(none)||Input Pin, Output Pin, Object Node, Activity Parameter||- The type of objects transmitted.|
- The type can be a primitive type such as Integer, or a classifier defined elsewhere in the model. If you enter the name of a type that is not defined, it will appear in the Unspecified Types section of UML Model Explorer.
|Multiplicity||1||Input Pin, Output Pin||- Can be a single value, or a range |
- Lower bound
- Upper bound
|Transformation||(none)||Object Flow||- Invokes a process that transforms the data. This process can be defined in another diagram.|
|Is Multicast||False||Object Flow||- Indicates that there might be several recipient objects or components.|
|Is MultiReceive||False||Object Flow||- Indicates that there might be several recipient objects or components.|
|Is Single Execution||False||Activity Diagram||- If set, there is at most one execution of this diagram at a time.|
