State Machines

State Machines illustrate how an element (often a Class) can move between states, classifying its behavior according to transition triggers and constraining guards.

·	State Machines were formerly known as State diagrams

·	State Machine representations in UML are based on the Harel State Chart Notation and therefore are sometimes referred to as State Charts
