State Machine Diagram Example: Composite State


This is a composite state machine. It consists of a state Active, with several child state Inspection, Choice and Transaction in it. State transitions are defined to represent the functions and conditions that trigger the state machine to transit from one state to another.

What is State Machine Diagram?

A state machine (also called, state chart, state tradition diagram, or simply state diagram) is a behavior which specifies the sequence of states an entity visits during its lifetime in response to events, together with its responses to those events. Typically, it is used for describing the behavior of classes, but state charts may also describe the behavior of other model entities such as use-eases, subsystems, operations, or methods.

Why state machines?

  • State machines are formally defined, they form executable models.
  • State machines can be visualized as diagrams and animated through simulators without writing any code.
  • You can simulate, test, debug state diagram as a virtual machine for a problem, for example, was the door locked with a card or a code?
