UML 活动图：决策分支结束整个活动

发布于 2024-08-08 20:39:44 字数 264 浏览 3 评论 0原文

我想知道是否有一种方法可以在有决定的活动上描述这一点；其中一个分支完全随着活动而终止。这类似于当满足条件时仅将控制权返回给调用者的子例程。

sub activity() {
   ...
   ...
   if ( condition ) {
      ...
   } else {
      return;//This branch finishes the activity
   }
   ...
}

谢谢，

I was wondering if there is a way to depict that, on an activity that has a decision; one of the branches completely terminates with the activity. This would be similar to a subroutine just returning control to the invoker when a condition is met.

sub activity() {
   ...
   ...
   if ( condition ) {
      ...
   } else {
      return;//This branch finishes the activity
   }
   ...
}

Thanks,

Carlos

以下代码如下图所示。

if (D1)
{
    if (D2)
    {
        return;
    }
}
else
{
    return;
}

     /\         /\
o___/D1\__T____/D2\__T_______0
    \  /       \  /          |
     \/         \/           |
     |____F__________________|

请注意，在这种情况下，D2:False 在图表和代码中都没有任何作用。我只是想说明导致活动结束的要点。（注：“0”是活动结束，“o”是开始）

The following code would look like the diagram below it.

if (D1)
{
    if (D2)
    {
        return;
    }
}
else
{
    return;
}

     /\         /\
o___/D1\__T____/D2\__T_______0
    \  /       \  /          |
     \/         \/           |
     |____F__________________|

Note, that in this case, D2:False goes nowhere, in both the diagram and the code. I was just trying to illustrate the points that lead to the end of the activity. (note: the '0' is the end of the activity and the 'o' is the start)
