EA&UML日拱一卒--序列图(Sequence Diagram)::条件执行 序列图提供了一种Fragment(片段),用来表现条件执行,循环,并发等情况。具体使用哪种Fragment,通过以下的对话框来选择。 今天先说条件执行相关的Fragment。 alt(alternative) alt用于表现条件执行的程序构造。和alt对应的程序结构可以是if/else结构,也可以是swtich结...

Alternative fragment(denoted “alt”) 与 if…then…else对应 Option fragment (denoted “opt”) 与 Switch对应 Parallel fragment (denoted “par”) 表示同时发生 Loop fragment(denoted “loop”) 与 for 或者 Foreach对应 三、时序图实例分析(Sequece Diagram Example Analysis) 时序图场景 完成课程创建功能,主...
- alt(Alternative):与if...else...或switch对应 - opt(Optional):可能发生也可能不发生的片段 - par(Parallel):并行发生 - loop [value]:与for 或foreach对应,[value]表示循环次数 时序图示例 以ATM取款为例 时序图注意事项 - 在时序图中根据重要性将对象从左到右排列,也可使用类来标识匿名对象 - 对象...

The label in the top-left corner indicates the fragment type (alternative, option, loop, or parallel), encapsulating complex or conditional behaviors in your system. Creating a UML sequence diagram Creating a sequence diagram can seem challenging, especially for complex systems. However, with ...
Alternative Combined Fragment Definition A combined fragment defines an expression of interaction fragments. A combined fragment is defined by an interaction operator and corresponding interaction operands. Through the use of CombinedFragments the user will be able to describe a number of traces in a co...
This combined fragment is modeled in the sequence diagram like the alternative. It also stands for a decision. However, there is only one operand. The decision is therefore decided on the basis of whether or not the operand should be executed. The operand with a condition must not be empty...
