Interaction Flow Control The Unified Modeling Language (UML) specification defines combined fragments to manage interaction flow through operators such as alt , opt , loop , and par . These fragments allow developers to model conditional logic and concurrency within a sequence diagram. Execution Semantics in Nested Fragments While the individual operators ha
In UML Sequence Diagrams, activation bars (execution occurrences) are used to denote the period during which a lifeline is performing an operation. When modeling asynchronous messaging, an open-headed arrow indicates that the sender does not block for a response. A design challenge arises when a message is sent asynchronously to a receiver, but the receiver
