    This must be such a WTF that I'm not even really following it.  The point of the class is to just wrap the setting and getting of the non-object variables?  Seems the author doesn't understand object property manipulation insomuch as objects in general...

    Actually, properties are usually wrapped around private variables.  The "setter" refers to the routine that takes a value and "sets" that private variable to that value.  The "getter" refers to the routine that returns the value of the private variable.

    The property pattern is actually pretty useful, and is definitely not the wtf here.  Often, when working in ASP.NET, I have the setter set not only the variable but also update the ViewState.  The problem here is that the property has a major side effect.  Code calling these properties would look like Contact.contact = theContact, which looks completely innocent.

    No it does make sence in an extreamly disturbing way, note that the code came from the Contact class. So you end up with something like:

    Contact c = new Contact();
    c.contact = new Contact(1234); // Populate the contact c from the database row with 1234
    Contact newContact = c.contact; // Save the contacts state to the database populating the ID

    Still an enourmouse WTF but I can see how they arived at this pattern. It would have made more sence if the type the accessors accept / return was an ID rather than a contact. Still would have been a stupid thing to do though.

  • TheValidator (unregistered)

    Well, it just looks to me like a write-on-access pattern, i.e you can set the contact, but it's only persisted if it's ever used.  I'd guess the idea is that you pass in an existing contact to clone it, and that clone is only saved to the database if it ends up being used somewhere.  It's similar to copy-on-write.

    There isn't enough code here to decide if it's a real WTF, SaveToDatabase() might have a 'dirty' flag set by LoadFromContact that let it decide if the contact does in fact need to be written or not.  Other properties might call SaveToDatabase when they are modified, etc.

    So is the WTF here supposed to be (aside from the switched logic of the get/set functions) that they do more than just obtain and modify some internal property and instead initiate some database transaction? What's wrong with a database abstraction layer?

  • (cs)

    Okay, I've been thinking about this for about 15 minutes now, and I think I've figured out what the original developer was doing.

    First of all, it doesn't make sense to give a Contact a property called "contact" that is also a Contact.  If we have a Contact bob, then I can understand who bob.mother and bob.father are, but who is bob.contact?

    Well, I guess it is this guy's way of saving and loading bob to/from the database!  Example:

    Contact bob = new Contact();
    bob.contact = "Bob"; // load contact identified by "Bob" from database
    // modify bob here
    Contact dummy = bob.contact; // save bob back to database

    Why he didn't just make SaveToDatabase() and LoadFromContact() public, we may never know.

  • (cs)

    what's wrong with this?

    this is what consultants do!... very interprisey indeed

  • (cs) in reply to Bill307

    Assuming my interpretation is correct, and that bob.contact == bob, the first code fragment could also be written as:

    <FONT color=#006400>// none of the following will save</FONT>
    string firstName = contactDetails.firstName;
    string lastName = contactDetails.lastName;
    string address1 = contactDetails.address1; 
    string address2 = contactDetails.address2;
    string primaryPhone = contactDetails.primaryPhone;

    Why address1 and address2 do not save is beyond me.  Maybe they really do save, but whoever added those lines didn't bother putting the "saves" comment.

  • (cs)

    That is indeed one bass-ackwards pattern, but I can kinda see it. I honestly can't see why you'd need such a pattern, other than to be sure that it saves the data to the database everytime anybody modifies it in certain ways. And the set is completely baffling. Yes, you could do bob.contact = "Bob" to load Bob's info in from the database (or wherever), but why you'd want to do it in that particular way is a bit beyond me.

    I find that it's hard to say whether the author is an absolute genius or a complete gibbering idiot. Either one of them could have written this code. :)

    Looking at it again, and at the comments above the property, I think I was wrong.  Now I'm pretty sure the parameter for LoadFromContact is supposed to be another Contact.  My best guess is that it actually copies the data from the passed Contact to this, as opposed to loading the data from the database.

    Who knows, maybe there is actually some use for always saving (or saving only if there have been changes) whenever a Contact is used :P.

  • RareButSeriousSideEffects (unregistered) in reply to justme

    I agree 'bout parentheses being annoying, but I can at least think of one aesthetic reason to use a Property where a Function would otherwise do; Functions grouped in the Methods section section of the Intellisense thingy (instead of with other Properties), and sometimes having consistent & reliable visual cues on things like that can make a larger than expected difference in productivity on a project.

  • deje162 (unregistered)

    There is absolutely nothing perverse about this save for the fact that OO programmers have so forgotten how to do OO that they think a getter is a proper part of OO programming. What is the point of a getter? you declare a field private and then expose it immediately as public thru a getter/setter pair? Ridiculous, just declare it public.

    The procedural people (read C and Basic) have infiltrated and messed up OO so much that they actually have you believing that it is perverse for an object to encapsulate a method like retrieving a value from a database. And to the people who say "a getter is useful to do a bit more before returning the value" you've either forgotten what interfaces are meant for or are ignoring the fact that 95% of all getters written out there do NOTHING but return the value (or both). Even the most ardent of the getter apologists will admit that. And before you go saying that only bad programmers write empty getters, take a look thru the last bean you wrote.

    Think how silly it would look if you wrote:

    private public int x;

    now think about what accessors and mutators do. C# programmers are somewhat off the hook because of properties, but if you look under the hood its just syntactic sugar and essentially does the same thing as a java/bean getter. Shame on you.

    I have to agree that there is nothing wrong with getter and setter methods actually doing something, including persisting the database. As to other expensive computation,
    I belive that is called lazy evaluation, and is definetly not a WTF.
     
    there are peristence framework out there which implement this basic idea (I know I am using one) and yes it makes the code simpler and cleaner as the persistence logic is nicly hidden.
     
    Based on the code there is a WTF (I still can't see WTF this the code is trying to achive by saving on access or how it is supposed to be used). I would however assume that addresses are treated as first calss objects and have there own (similer) persitence code built in.

    agreed, but a small correction: lazy initialization not lazy evaluation. lazy init is lazily fetching portions of an object graph not immediately needed (which hibernate actually uses dynamic proxies for so it doesnt even really need getters).

    lazy eval is a language feature which delays evaluation of an expression until it is needed. java does not support this (java is strict-evaluative), neither does c# or any other imperative/OO language.

    and just use the HTML editor.  Surround code and whatnot in <pre> tags and use <br> tags to insert "newlines".  If you want to be sure, copy the HTML to a file and open it up in a browser and see how it renders.
