执行下面序列图中的 save() 消息后是否会发生中断？
最佳答案
是的。
来自 UML2.5 的定义
Break
The interactionOperator break designates that the CombinedFragment represents a breaking scenario in the sense that the operand is a scenario that is performed instead of the remainder of the enclosing InteractionFragment. A break operator with a guard is chosen when the guard is true and the rest of the enclosing Interaction Fragment is ignored. When the guard of the break operand is false, the break operand is ignored and the rest of the enclosing InteractionFragment is chosen. The choice between a break operand without a guard and the rest of the enclosing InteractionFragment is done non-deterministically.
A CombinedFragment with interactionOperator break should cover all Lifelines of the enclosing InteractionFragment.
