Adding triggers to state machine diagrams
In UML models, a trigger
is an event that initiates a transition from one state to another.
A guard condition is a Boolean condition that must be satisfied for
a transition to occur. An effect is the action or activity that happens
when a transition occurs.
- Adding call events to state machine diagrams
In UML models, a call event is an event that represents the receipt of a request to invoke an operation. A transition with a call event initiates when the called operation is invoked. - Adding change events to state machine diagrams
In UML models, a change event is an event that represents a condition. The condition is defined by a Boolean-valued expression that triggers a transition when its value changes from false to true. - Adding signal events to state machine diagrams
In UML models, a signal event represents a specific message that initiates a transition when an object receives it. - Adding time events to state machine diagrams
In UML models, a time event is an event that represents the passage of a defined period of time or an absolute time. A transition with a time event trigger initiates when the time value is satisfied. - Adding any received event triggers to state machine diagrams
In UML models, you can add triggers to state machine diagrams for any received event, which means that any type can trigger the event. This type of transition triggers on any event, as long as no other event trigger type is connected to the source state. - Adding call events to state machine diagrams
