How to make the cleanest code when reporting progress to a user?

Question

I\'ve struggled for the last couple of months to come up with some clean code to report progress to a user. Everything always seems to boil down to:

ReportProgr         


        

Answer 1

A fairly simple and clean way would be to create an abstract class that has a do() method and abstract doTask() and getName() methods:

do() {
    ReportProgress("Starting " + this.getName());
    doTask();
    ReportProgress("Finished " + this.getName());
}

Then in your tasks:

class Task1 extends Task {
    getName(){return "Task 1";}
    doTask() {
        //do stuff here
    }
}

You could then have a Task that has a doTask() method that runs do() on a whole bunch of other tasks. This could easily be recursive, in that any Task might then run a number of sub-Tasks.
