What is a State Machine Diagram?
A state diagram is used to represent the condition of the system or part of the system at finite instances of time. It’s a
behavioral diagram and it represents the behavior using finite state transitions.
- State Machine diagrams are also referred to as State Machines Diagrams and State-Chart Diagrams.
- These terms are often used interchangeably. So simply, a state machine diagram is used to model the dynamic behavior of a class in response to time and changing external stimuli.
- We can say that each and every class has a state but we don’t model every class using State Machine diagrams.
- We prefer to model the states with three or more states.
Let’s understand State Machine Diagram with the help of an example:
Example:
The State Machine Diagram above shows the different states in which the verification sub-system or class exist for a particular system.
