Element: Fork/Join The fork is a pseudo state to split transitions to pseudo-parallel processing in orthogonal states. All transitions that originate from a fork are completion transitions that have t
Element: Choice A choice is a node in a statechart. The subsequent guard conditions are evaluated at the node within a cycle. It has at least one incoming transition and one outgoing transition. Choic
Element: Transition A transition controls the transition behavior between states. . A transition is possible when one of the following events occurs: Conditional event or change event Completion event
