Fluent interfaces in the JADE source code

November 6th, 2008 · 8 Comments

Recently I have been toying around with fluent interfaces. Traditionally I preferred the classical Java Bean style of method naming (get/set) and definition but on several occasions (see past posts) fluent interfaces crept into JADE.

Today I added some potions to JADE that either grant positive or negative attribute modifiers for a certain amount of time. They are modeled by conditions which a being can be in. Each condition has certain effects and to put a being into a condition you have to create a so-called ConditionDefinition. And this - for attribute modifiers - now is done with a fluent interface. The original code (before refactoring temporary attribute modifications to the Being base class) looked like this:

public class AbstractAttributeBoostingPotion
  extends AbstractPotion
{
  private Attribute attribute;
  ...
  protected void drinkImpl(Being being)
  {
      ConditionDefinition attributeModification
          = attribute.modifier(status().based(+1, +3, +5))
                     .lasting(status().based("4d4", "8d6", "12d8")).actions();
      being.inflict(attributeModification);
  }
}

Oh, BTW… 18 potions also were added ;-)

    Cool! How are you doing with that Ph.D Work?

    Looking good.

    It is very bad style!
    For example (C# 3.5):

    class SomeSettings {
    public Color Color { get; set; }
    public double Height { get; set; }
    public double Weight { get; set; }
    }

    class Program {
    static void Main (string [] args) {
    SomeSettings settings = new SomeSettings { Color = Color.Black, Height = 10d, Weight = 20d };
    }
    }

    Could you please upload the latest javadoc?

    I find it extremely interesting to read, but the one that’s online is horribly out of date (it’s from 2004)…

    Thanks!

    Doh, no new Adom version, :(

    Stop Developing JADE, work on ADOM. It is your greatest developing achievement. I regret that you did not finish it. Version 1.1.1 is not perfect. It need some improvements.

    Work on Jade on your retirement, when you will have a lot of free time. Now, when you don’t even have time to post one message on blog you should not work on big thing like JADE.

    “Dear Thomas,

    Since life is so short, and a man can achieve only a limited amount of thing in is short life span, I beg you to cure cancer, world hunger, and war (can you bitchslap all these hippies too ? pleaaase!)

    When you’ll have done all these thing, you’ll be probably so old and senile that it’ll be time to work on ADOM.

    After that, you may take a break, die, or work on Jade,

    Thanks,
    Sincerly,”

    Here, fixed it for you, L. :p

    So I’m not the only one who says that he will release the first version of JADE after his retirement XDDXDD

    Think about it a little, L, if he does not have time to program JADE, I’m certain that he will not have time to program ADoM, Either.
