A statechart diagram shows a state machine, focusing on the flow of control from state to state. A state machine is a behavior that specifies the sequences of states an object goes through during its lifetime in response to events, together with its responses to those events. Common Properties A statechart diagram is […]
Introduction A state machine is a behavior that represents the sequences of states that an object undergoes during its lifetime in response to events, together with its responses to those events. The state of an object is a condition or situation during the life of an object during which it satisfies some condition, […]
Introduction In state machines (sequence of states), we use events to model the occurrence of a stimulus that can trigger an object to move from one state to another state. Events may include signals, calls, the passage of time or a change in state. In UML, each thing that happens is modeled as […]
Introduction An activity diagram is like a flowchart, representing flow of control from activity to activity, whereas, the interaction diagrams focus on the flow of control from object to object. Activities result in some action, which is made up of executable atomic computations that result in a change of state of the system […]
Introduction An interaction diagram represents an interaction, which contains a set of objects and the relationships between them including the messages exchanged between the objects. A sequence diagram is an interaction diagram in which the focus is on time ordering of messages. Collaboration diagram is another interaction diagram in which the focus is […]
