Question

I have the following method:

public override bool IsSatisfiedBy(SourceFile candidate)
        {
            Console.WriteLine("Check 1: " + One.IsSatisfiedBy(candidate));
            Console.WriteLine("Check 2: " + Two.IsSatisfiedBy(candidate));
            Console.WriteLine("Check 3: " + Three.IsSatisfiedBy(candidate));
            return One.IsSatisfiedBy(candidate) && Two.IsSatisfiedBy(candidate) && Three.IsSatisfiedBy(candidate);
        }

If i pass a SourceFile as an argument that not fulfills rule one, then rule two and three aren’t checked. I know that this is the correct way, but I would like to read more about the exact behaviour but I can’t find anything because I don’t know what this behaviour is called 😀

Answer 1

It’s called short-circuit evaluation. In C# it happens for the && and || operators.
