20.16. Fork

Fork is a pseudostate (see Section 20.11, “Pseudostate”) which splits a transition into two or more concurrent transitions.

[Caution]Caution

The outgoing transitions should not have guards. However ArgoUML will not enforce this.

A fork is represented on the diagram as a solid (black by default) horizontal bar.

[Tip]Tip

This bar can be made vertical by selecting the fork, and dragging with button 1 one of its corners.
