Annotation

A guard is a constraint that provides a fine-grained control over the firing of the transition. The guard is evaluated when an event is dispatched by the state machine. If the guard is true at that time, the transition may be enabled, otherwise, it is disabled. Guards should be pure expressions without side effects. Guard expressions with side effects are ill formed.
