• Separating Db from business with Inherited classes using multiple views

  - by catalinux

  I have a software that has a car model that will be used in different views (listing, ads, detail page, carousel, up sell widget,etc). class CarModel extends DbModel{ } I look for a "nice way" (a combination of flexible, easy to maintain,etc) to have this used in views. I'm thinking at two different ways Having object views for each context CarViewBase{ var car;// of type CarModel function constructor(args){ //will instantienta internal variable car based on args } function getThumb(){ } function getTitle(){ } } CarListingView extends CarViewBase{ function getListing(){ } } CarAdsView extends CarViewBase{ //the busines rule changes for ads widget function getThumb(){ } } Extending directly the CarModel The challenges comes when My Car Model might need an abstract factory. Let's say I have a field on my car object that states the type of the car : a truck, or a bike, or van. How would affect that my object view? Let's say that getTitle() rule would be different for each type of it. How would you do it?

• Are there any tools for performing static analysis of Scala code?

  - by Roman Kagan

  Are there any tools for performing static analysis of Scala code, similar to FindBugs and PMD for Java or Splint for C/C++? I know that FindBugs works on the bytecode produced by compiling Java, so I'm curious as to how it would work on Scala. Google searches (as of 27 October 2009) reveal very little. Google searches (as of 01 February 2010) reveal this question.

• why can't a static member be reached through an instance name?

  - by reinier

  say I have: class Test { public static int Hello = 5; } This obviously works: int j = Test.Hello; But why should this not work? Test test = new Test(); int j = test.Hello; The instance could not have a member equally named, so I don't see how this could be ambiguous or unresolvable for a compiler. Anyone any idea why this is?

• in ASP.Net, are long running static operations a bottleneck?

  - by Laramie

  If a long running operation is defined in a frequently called static method, is it a bottleneck for other threads in an ASP.Net application trying to call the same method? Does that only apply to methods with the "Synchronized" attribute? I've searched and can't seem to find a definitive answer.

• Can a Static Nested Class be Instantiated Multiple Times?

  - by stormin986

  Given what I know of every other type of static feature of programming––I would think the answer is 'no'. However, seeing statements like OuterClass.StaticNestedClass nestedObject = new OuterClass.StaticNestedClass(); makes me wonder.

• Can you attach a CMS to an existing static web site created in Dreamweaver?

  - by Daniel Olds

  I am not a programmer, but a designer. I created a static web site in Dreamweaver (CS4) and my client would like to be able to update a news page on his own. I have looked in to several CMS options and haven't found one that seems to fit my needs. Mainly, simple to set up, possible to set up and, preferrably, free to set up. Any suggestions? I'm all ears. Thanks

• In java, is there any disadvantage to static methods on a class?

  - by Michael Campbell

  Lets assume that a rule (or rule of thumb, anyway), has been imposed in my coding environment that any method on a class that doesn't use, modify, or otherwise need any instance variables to do its work, be made static. Is there any inherent compile time, runtime, or any other disadvantage to doing this?

• C#: Do I need to lock a static class when accessing from separate threads?

  - by JimDaniel

  I have a static class with a few methods that just take in a byte array, parses it, and returns a structure. I need to call these methods from many separate threads. Do I need a lock() or some kind of thread-safety within the methods? I can't get my head around it.

• Using java classes in Grails

  - by RN

  I have a Java\Spring\Hibernate application - complete with domain classes which are basically Hibernate POJOs There is a piece of functionality that I think can be written well in Grails. I wish to reuse the domain classes that I have created in the main Java app What is the best way to do so ? Should I write new domain classes extending the Java classes ? this sounds tacky Or Can I 'generate' controllers off the Java domain classes ? What are the best practices around reusing Java domain objects in Grails\Groovy I am sure there must be others writing some pieces in grails\groovy If you know about a tutorial which talks about such an integration- that would be awesome !!! PS: I am quite a newbie in grails-groovy so may be missing the obvious. Thanks !!!

• Managing of shared resources between classes?

  - by Axarydax

  Imagine that I have a several Viewer component that are used for displaying text and they have few modes that user can switch (different font presets for viewing text/binary/hex). What would be the best approach for managing shared objects - for example fonts, find dialog, etc? I figured that static class with lazily initialized objects would be OK, but this might be the wrong idea. static class ViewerStatic { private static Font monospaceFont; public static Font MonospaceFont { get { if (monospaceFont == null) //TODO read font settings from configuration monospaceFont = new Font(FontFamily.GenericMonospace, 9, FontStyle.Bold); return monospaceFont; } } private static Font sansFont; public static Font SansFont { get { if (sansFont == null) //TODO read font settings from configuration sansFont = new Font(FontFamily.GenericSansSerif, 9, FontStyle.Bold); return sansFont; } } }
