A Transition terminating on this Pseudostate implies rest A Pseudostate is an abstraction that encompasses different types of transient Vertices in the StateMachine graph. A StateMachine instance never comes to rest in a Pseudostate, instead, it will exit and enter the Pseudostate within a single ... step Two types of history Pseudostates are provided. Deep history (deepHistory) represents the full state configuration of the most recent visit to the containing Region. The effect is the same as if the Transition terminating on the deepHistory Pseudostate had, instead, terminated on the innermost State of the preserved state configuration, including execution of all entry Behaviors encountered along the way.
