Used in a statechart diagram, a history state indicator represents the substate last visited. When a transition to the indicator fires, an object resumes the state it last had at the same level as the history indicator.
An asterisk ''*'' attached to the ''H'' represents deep history. When a transition to a deep history indicator fires, an object can resume a state at any depth within a complex region. A region may include both a shallow and deep history state indicator.
