What is the design template for this?

Question

I have a process similar to a workflow, suppose it is:

• Training
• Eat
  • Take your stuff to the basket
  • Table cleaning

Now, what I want to do, even the user cancels the "Eat" event, which I want them to "Clear the table", the same applies to the stages "Prepare" and "Take your stuff to the basket."

Currently, in my implementation, I had to perform several checks, and sometimes I end up calling the Clear Table twice, and some other branching problems, when I add a couple more steps.

Is there any well-defined design pattern for working with such flows? (AFAIR was alone, I just can't remember his name.)

Answer 1

This is solved using the State pattern . If you check the drive, the logic goes smoothly.

Answer 2

Sounds like a template template template .

Or you can do it using composition and strategy template .

If you have complex logic, then the State pattern might be better.

Answer 4

#/.NET IDisposable. , - , , ( ).

Regarding the workflow aspect, I will just follow the WCF web service design pattern (i.e. Beginand Cancel). If you don't find this redundant for your circumstances, the Windows Workflow Foundation may be the best way.

Answer 5

State Pattern my firend is what will end this work.
