Result Pattern (in Apex)

This repository contains the base classes for the implementation of the Result Pattern, as seen in some C# examples, such as the blog post by Milan Jovanović.

Usage

Using a Result class allwows you to express the intent that a method could fail and encapsulate an application error inside.

See the Sample.cls class:

public static Result checkIfGreaterThan100(Integer n) {
    if (n > 100) {
        return Result.Failure(new Result.Error('It can not be higher than 100!'));
    }

    return Result.Success();
}

public static List<Result> checkifGreaterThan100ForMultipleItems(List<Integer> ns) {
    for (Integer n : ns) {
        Results.yield(checkIfGreaterThan100(n));
    }

    return Results.collect();
}
