How about "Pin A Mutt"? Kind of like "Pin the tail...", however I'm thinking along the lines of blindfold, crochet(sp?) needle, and a live dog running around. PETA may have a problem with that. Big Grin | :-D

PS When I had a dog, I'd never have volunteered him for this "game".

The closest version of this that I could see without contemplating my navel would be an Identity Map. It's not a 100% fit, but it does fit some of your intent.

Interesting. I have also implemented this in my framework, but I just called it caching.

Most people do.

First law of patterns. They are a fancy name for stuff you already do.

Along with the first law of programming ( "it's already been done" ), I was hoping someone had already come up with the fancy name.

Like AJAX, we were doing that "call the server without reloading the page" years before they came up with the name, first using hidden frames, then iFrames and finally XmlHttpRequest!.

And Ajax will always remain a cleaning product for me, not a programming thing.

Agreed. Some 10 years ago, when I designed an architecture and had it reviewed, I've been told that I've implemented an Observer Pattern. I had to ask what he was talking about - I had never heard of Design Patterns before!

After reading up about them I realized they only really described a ton of things I already knew and did use.I just didn't think to come up with a name for these patterns and write a book! Roll eyes | :rolleyes:

I like to call it poor programming. But I am outnumbered in the MS world.

Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting. I also do Android Programming as I find it a refreshing break from the MS.

You can design any method to use a predicate like that. It isn't rocket science - it's LINQ:

Copy Code

IEnumerable<T> Fetch<T>(Func<T, bool> predicate){
    return repository.Where(predicate);
}

...as long as you are using the repository that contains type `T`.

I know. I use it every day. I was merely suggesting a name that attempted to describe what the OP was doing.

If they had got the hint, they might have opted to modify their Framework/Wrapper/WhateverItWasTheyCalledItICantBeArsedToGoBackAndLook.

If I had suggested changes, that would be turning The Lounge into a programming forum, which it ain't. Smile | :)

As an alternative, it also looks a bit like a Query Object - mapping onto a Repository pattern.

I'm thinking condition-based programming. I'm not sure if I just made that up right now though.

Also, isn't that exactly the type of thing you can already do with a Linq query?

It is elegant, just like Linq, and it's a good thing to do as long as you can implement it in such a way that the condition is only executed as little as possible, and you don't have to load the whole potential result set into memory and then filter it.

It's more functional programming than declarative, I think. In languages where functions are first class objects (e.g. Javascript) it is more common to pass filter functions or other types of function (for example a sort order comparator) around and potentially declare them locally as you have done here. What you're passing in the 'where' parameter is a pure function.

Yes, it's certainly like Linq Big Grin | :-D

The difference is that it may or may not cause a Linq-to-Entities query to run and hit the database server.

Yes, I suppose it is. I was focused on making it easy to use rather than the programming paradigm.

Thanks,

It does hide a lot of complexity, but I think the difference is that the parameters passed are functions not values.

I don't know if that makes it a different pattern, though Smile | :)

From the all knowing Wikipedia:

A facade is an object that provides a simplified interface to a larger body of code, such as a class library. A facade can:

- make a software library easier to use, understand and test, since the facade has convenient methods for common tasks;
- make the library more readable, for the same reason;

Certainly sounds like its a facade based on that definition Smile | :)
