If something of interest happens in the environment, a thing or service fires an event with which the State Flow is called and which it then tries to handle. A State Flow is hence event-driven, reactive and does not include much human interaction. Have a look at Irene’s recent post for an example use case in the field of industrial IT.

In general, it consists of two parts: A graphical editor to model State Flow diagrams (see figure 1) and a Java class, the so-called Controller, to execute the State Flow, i.e. to call it with the current event.
