Basic information about the state diagram and its elements

State diagram - one of the available kinds of graphs supported Flexberry Designer.


It shows how the object transitions from one state to another. State diagrams are used to model the dynamic aspects of the system. This diagram is useful when modelling the life cycle of the object. From other diagrams state diagram differs in that it describes the process of changing the state of only one instance of a particular class - the same object, with object reactive, that is, an object whose behavior is characterized by its response to external events.
