States
Overview
A state describes a mode of a reactive system. States in a Stateflow diagram represent these modes. The activity or inactivity of the states dynamically changes based on events and conditions. Every state has hierarchy. In a Stateflow diagram consisting of a single state, that state's parent is the Stateflow diagram itself. A state also has history that applies to its level of hierarchy in the Stateflow diagram. States can have actions that are executed in a sequence based upon action type. The action types are:entry, during, exit, or on event_name actions.
