Object Flow shape

In an activity diagram, an object flow indicates that an object is an input for or output by an action. An object flow arrow connects an object flow state either to a control flow arrow or to an action state.

When an object flow arrow supplies a redundant constraint, you can omit the control flow arrow.

Name an Object Flow shape and add other property values

Open the element's UML Properties dialog box by double-clicking the icon that represents the element in the tree view or the shape that represents the element in a diagram.

Tip

Control which property values display on a shape in a diagram by right-clicking the shape, and then clicking Shape Display Options. In the UML Shape Display Options dialog box, select and clear options to display or hide property values.
