The initial state of a state machine diagram, known as an initial pseudo-state, is indicated with a solid circle. This is how a state diagram works. The State Diagram • We will use the state diagram to specify the sequencing / timing behavior of objects in a class - States - Events - Transitions • Generally speaking, there should be one state diagram for every class - But this is not prescribed by UML, it allows state … Statechart diagram is one of the five UML diagrams used to model the dynamic nature of a system.
