== Where does criticism come from? ==

There is no citation or reference of any kind with the criticisms. They may be valid but seem to be the opinion of the author. --[[Special:Contributions/4.14.21.30|4.14.21.30]] ([[User talk:4.14.21.30|talk]]) 14:18, 29 March 2018 (UTC)

...I have to admit I may have missed the point, but is this "pattern" just a way to do Boolean logic with a few pages of new classes and code? Cause, yeah--I've been stringing together Boolean values with logical operators for a long time.

== Class explosion + bad explanation ==

First, this article has a pretty bad explanation and needs to be cleaned up. I'll try, but I'm not a design pattern expert by any means, even though I am a CS student and have taken a software engineering course. It just seems like this design pattern is a big absurd in implementing boolean logic through classes. Such operators exist in every language, why would classes need to exist to perform their function? And then on top if this, you need even more classes to implement every little detail of specification needed. If anyone has some good criticisms, maybe this could have a criticism section too... (a web search didn't turn up anything, but I haven't checked any journals) [[User:HebrewHammerTime|HebrewHammerTime]] 09:19, 26 September 2007 (UTC)

:: Of course I would use this pattern in a functional language. It's just not as apparent, because you can do it in a few lines of code instead of a mess like the one we have right now. ("simplified"... yeah...) But I am torn up if replacing the code with a shorter, clearer, functional variant would be a good idea, as fewer people understand Lisp or Haskell. --[[Special:Contributions/47.70.172.238|47.70.172.238]] ([[User talk:47.70.172.238|talk]]) 01:28, 20 November 2015 (UTC)

The distinction between this and [[Interpreter pattern]] is unclear to me. Perhaps this is a special case of Interpreter?

:-- Second that [[User:Dubwai|Dubwai]] The Specification as explained here is special case of Interpreter. To quote the first article from the list "This effectively creates an interpreter [Gang of Four] for the specification. The "language" being interpreted allows us to describe a composite specification." and connection with Interpreter should be made clear. <small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/190.21.127.98|190.21.127.98]] ([[User talk:190.21.127.98|talk]]) 18:17, 27 December 2014 (UTC)</small><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

Shouldn't the lower right-hand class be labelled ''NotSpecification''? --[[Special:Contributions/132.181.52.8|132.181.52.8]] ([[User talk:132.181.52.8|talk]]) 05:02, 2 July 2009 (UTC)

== Content Doesn't make sense ==

The text is confusing at one point, and talks about a previously implemented class, which is not linked or shown anywhere. It looks like this may be copied from some other source, and as such may be plagerized.

== External links modified ==

Hello fellow Wikipedians,

I have just added archive links to {{plural:1|one external link|1 external links}} on [[Specification pattern]]. Please take a moment to review [https://en.wikipedia.org/w/index.php?diff=prev&oldid=706406351 my edit]. If necessary, add {{tlx|cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{tlx|nobots|deny{{=}}InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

*Added archive https://web.archive.org/20110724151447/http://www.dpdk.nl/opensource/specification-pattern-for-selection-on-lists to http://www.dpdk.nl/opensource/specification-pattern-for-selection-on-lists

When you have finished reviewing my changes, please set the ''checked'' parameter below to '''true''' to let others know.

{{sourcecheck|checked=false}}

== Comparison with false ==

I'm no C# guru but wouldn't one prefer to write

... && !currentInvoice.NoticeSent && ...

instead of

... && currentInvoice.NoticeSent == false && ...
