State Machine Diagrams. Two kinds of state machines defined in UML 2. A state machine diagram models the behaviour of a single object, specifying the sequence of events that an object goes through during its lifetime in response to events. As an example, the following state machine diagram shows the states that a door goes through during its lifetime. The door can be in one of three states : .

In UML, states are represented as rounded rectangles labeled with state names. The transitions, represented as arrows, are labeled with the triggering events followed . Benzer Bu sayfanın çevirisini yap UML state machine diagrams depict the various states that an object may be in and the transitions between those states. In fact, in other modeling languages, it is common for this type of a diagram to be called a state-transition diagram or even simply a state diagram. A state represents a stage in the behavior pattern of an . A UML state machine Diagram for a seminar during enrollment. A Seminar object is fairly complex, reacting to events such a enrolling a student differently depending on its current state, as you see depicted in Figure 1. The behavior of an entity is not only a direct consequence of its inputs, but it also depends on its preceding state.

The past history of an entity can best be modeled by a finite state machine diagram or traditionally called automata. The history of an entity can best be modeled by a finite state diagram. A state diagram shows the behavior of classes in response to external stimuli. Specifically a state diagram describes the behavior of a single object in response to a series of events in a system. This UML diagram models . Important type of UML diagrams.

Behaviour of operations. For modelling behaviour. Beckert: Formal Formal Specification of Software – p. One can model the state and the changes in state of an object in dependency on executed operations. Special value is placed on the changeover from one state to the next.

Good Morning Does anyone know how to bring up the name of the transition to a state diagram. By default, we only see the guard condition. In UML modeling, states represent the changing behavior of an object.

A change of state is described using a transition to show a path between two states.
