Let's say I want to enforce a rule:
Everytime you call "StartJumping()" in your function, you must call "EndJumping()" before you return.
When a developer is writing their code, they may simply forget to call EndSomething - so I want to make it easy to remember.
I can think of only one way to do this: and it abuses the "using" keyword:
class Jumper : IDisposable {
public Jumper() { Jumper.StartJumping(); }
public void Dispose() { Jumper.EndJumping(); }
public static void StartJumping() {...}
public static void EndJumping() {...}
}
public bool SomeFunction() {
// do some stuff
// start jumping...
using(Jumper j = new Jumper()) {
// do more stuff
// while jumping
} // end jumping
}
Is there a better way to do this?
