UML Activity diagram: decision branch ends whole activity

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 开发者_开发知识库( condition ) {
      ...
   } else {
      return;//This branch finishes the activity
   }
   ...
}

Thanks,

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)
