  • is 'protected' ever reasonable outside of virtual methods and destructors?

    - by notallama
    so, suppose you have some fields and methods marked protected (non-virtual). presumably, you did this because you didn't mark them public because you don't want some nincompoop to accidentally call them in the wrong order or pass in invalid parameters, or you don't want people to rely on behaviour that you're going to change later. so, why is it okay for that nincompoop to use those fields and methods from a subclass? as far as i can tell, they can still screw up in the same ways, and the same compatibility issues still exist if you change the implementation. the cases for protected i can think of are: non-virtual destructors, so you can't break things by deleting the base class. virtual methods, so you can override 'private' methods called by the base class. constructors in c++. in java/c# marking the class as abstract will do basically the same. any other use cases?

  • Depending on another open source library: copy/paste code or include

    - by user5794
    I'm working on a large class and started implementing new features that need graphics. I started writing the graphics functions myself, but I know that open source libraries exist that can provide me with this functionality without me having to write it myself. The problem is that I prefer the class to be self-sufficient and not dependent on any other library. If I don't write it myself, I would have to ask the user to make sure a graphics library is already installed (less user-friendly). If I write it myself, I do a lot more work than I have to. I could also copy/paste some of the relevant code into my own class, but not sure about the disadvantages of doing this (it's an open source library that matches my license, so I'm not concerned with legality, just programming-wise if there are disadvantages). So what should I do: copy paste code from the external library write the code myself so it's truly self-sufficient ask the user to download and install another library

  • How can I superscript a single character throughout my site?

    - by dvn66
    Finishing up development work for a client and they have a late request to superscript every occurrence of the &reg character throughout the site. I merely get by with CSS, but not even sure CSS provides the best solution here. how can I make a global change to every occurrence of a single character in the site copy without going back and adding tags everywhere? if the best solution does involve inserting a span or other tag I'm thinking it could be accomplished with a database query (all the copy is wired up to a CMS).

  • Starting android Development

    - by Tamim Ad Dari
    I am considering learning android development. I have some basic knowledge in C++. I downloaded the ADT plugin and eclipse. Now while starting from http://developers.android.com I see the codes were in XML. So I googled for learning XML. The best site I found was http://www.w3schools.org but there I found that for learning XML I have to learn HTML and CSS. So I learned the basics of HTML and CSS. But, Now I find in that learning java is a must. So can someone give idea about the sequental languages that I should study now? Should I learn php,mysql too. BTW, I have a dream to work in google :p

  • Does this factory method pattern example violate open-close?

    - by William
    In Head-First Design Patterns, they use a pizza shop example to demonstrate the factory method pattern. public abstract class PizzaStore { public Pizza orderPizza(String type) { Pizza pizza; pizza = createPizza(type); pizza.prepare(); pizza.bake(); pizza.cut(); pizza.box(); return pizza; } abstract Pizza createPizza(String type) } public class NYPizzaStore extends PizzaStore { Pizza createPizza(String item) { if (item.equals("cheese") { return new NYStyleCheesePizza(); } else if (item.equals("veggie")) { return new NYStyleVeggiePizza(); } else if (item.equals("clam")) { return new NYStyleClamPizza(); } else if (item.equals("pepperoni")) { return new NYStylePepperioniPizza(); } else return null; } } I don't understand how this pattern is not violating open-close. What if we require a beef Pizza, then we must edit the if statement in the NYPizzaStore class.

  • Can data classes contain methods for validation?

    - by Arturas M
    OK, say I have a data class for a user: public class User { private String firstName; private String lastName; private long personCode; private Date birthDate; private Gender gender; private String email; private String password; Now let's say I want to validate email, whether names are not empty, whether birth date is in normal range, etc. Can I put that validation method in this class together with data? Or should it be in UserManager which in my case handles the lists of these users?

  • what else except web development is a good choice for freelancing? [closed]

    - by Sali
    I'm looking for a technology that when I learn I can build useful things that brings money by selling what I have built. I tried web development but Ifound that there are many things that I have to learn: html, css, javascript,ajax,jquery ,etc. I need to focus on one thing and learning it from scratch and continue learning if there is any update in that technology rather than learning new things in css and javascript and the server side language. I want to focus! However, I'm not sure what is going on in the future of technology and I need to learn something for freelancing. could you tell what is the thing thatis popular and will bring me money as good as web development?

  • Continuing Education as a Part of Your Job [closed]

    - by Mike
    I work as a programmer for a mid-sized company (about 500 employees) in the medical industry. Before that I worked at a custom software development/consulting company. At both companies programmers were never officially given time to continue their education through taking classes, reading books or blogs, or doing research relevant to the job. At the software development company we were offered some money to pay for a class, but not offered any time off of work to take the class. I have been wondering, do most employers of programmers give time off of work to take a class, read a book, or do job related research? By time off of work I just mean some period of time where you can stop development; it does not have to mean leaving the office. I would be grateful to hear about everyone's experience with this.

  • Is this a pattern? Proxy/delegation of interface to existing concrete implementation

    - by Ian Newson
    I occasionally write code like this when I want to replace small parts of an existing implementation: public interface IFoo { void Bar(); } public class Foo : IFoo { public void Bar() { } } public class ProxyFoo : IFoo { private IFoo _Implementation; public ProxyFoo(IFoo implementation) { this._Implementation = implementation; } #region IFoo Members public void Bar() { this._Implementation.Bar(); } #endregion } This is a much smaller example than the real life cases in which I've used this pattern, but if implementing an existing interface or abstract class would require lots of code, most of which is already written, but I need to change a small part of the behaviour, then I will use this pattern. Is this a pattern or an anti pattern? If so, does it have a name and are there any well known pros and cons to this approach? Is there a better way to achieve the same result? Rewriting the interfaces and/or the concrete implementation is not normally an option as it will be provided by a third party library.

  • Azure Table&ndash;Entities having different Schema (Implementation Approach)

    - by kaleidoscope
    Below is the approach that can be implemented whenever there is a requirement of creating an Azure Table having entities with different schema definitions.   We can have a Parent Entity defined which will hold the data common in all the entity types and then rest all entities should inherit from this parent class. There will be only on DataServiceContext class which will accept the object of the Parent class and this can be used for CRUD operations of all the entities. Hope this approach helps! Thanks.

  • Fiscal quarter vs calendar quarter

    - by Geotarget
    I'm building a Date/Time class with a "configurable quarter" system as follows. User specifies which month the quarter starts at (config) Set of functions to deal with quarters (next quarter, prev quarter, etc) All quarter functions respect the config Now this class is primarily to be used for fiscal quarter calculations. So assuming I have this class with a configurable "quarter" system, would I need another parallel set of functions for calendar quarters too? What are the applications for calendar quarters anyways? By calendar quarters I mean where Q1 is Jan-Mar, and Q4 is Oct-Dec. By fiscal quarters I mean whatever standard your Country uses (in India Q1 starts in April)

  • Placing advice on any parameter of a given type in AspectJ

    - by user12558
    Hi, Im doing a POC using Aspectj. class BaseInfo{..} class UserInfo extends BaseInfo{..} class UserService { public void getUser(UserInfo userInfo){..} public void deleteUser(String userId){..} } I've defined an advice, that gets invoked when I pass an UserInfo instance.But when i try to pass the BaseInfo, the advice is not getting invoked. Below block executes the afterMethod as expected for getUser. &ltaop:pointcut id="aopafterMethod" expression="execution(* UserService.*(..,UserInfo,..))" / &gtaop:after pointcut-ref="aopafterMethod" method="afterMethod" / But when i try to give BaseInfo instead of UserInfo, the aspect is not getting triggered. Am i missing something? Kindly help me on this issue.

  • Should interface only be used for behavior and not to show logical data grouped together?

    - by jags
    Should an interface only be used to specify certain behavior? Would it be wrong to use interface to group logically related data? To me it looks like we should not use interface to group logically related data as structure seems a better fit. A class may be used but class name should indicate something like DTO so that user gets the impression that class does not have any behavior. Please let me know if my assumption is correct. Also, are there any exceptions where interface can be used to group logically related data?

  • How is this "interface"-like structure/pattern called?

    - by Sebastian Negraszus
    Let's assume we have an XmlDoc class that contains basic functionality for dealing with an XML data structure and saving/loading data to/from a file. Now we have several subclasses, A, B and C. They all inherit from XmlDoc and add component-specific methods for setting and getting lots of data. They are like "interfaces" but also add an implementation for the signatures. Finally, we have an ABCDoc class that joins all the "interfaces" via virtual multiple inheritence and adds some ABCDoc-specific stuff, such as using XMLDoc-methods to set an appropriate doc type. We may also have an ADoc class for only saving A data. How is this pattern called? "Interface" is not really the right word since interfaces usually do not contain an implementation. Bonus points for C++ code conventions.

  • Where Are Multiple JUnit Test Methods Typically Placed in Code?

    - by Thunderforge
    I've just read the Vogella JUnit tutorial and found it very helpful in understanding how to use JUnit. However, I'm a bit confused about what the convention is for placing multiple test methods in code. The tutorial only places one test method in a class, then describes how you can use a test suite to group multiple test classes together. Does this mean that it's common practice for each test class to only have one test method and then test suites are used to chain them together? Or was that just unintended and instead common practice is to put multiple test methods in a class?

  • Classless tables possible with Datamapper?

    - by barerd
    I have an Item class with the following attributes: itemId,name,weight,volume,price,required_skills,required_items. Since the last two attributes are going to be multivalued, I removed them and create new schemes like: itemID,required_skill (itemID is foreign key, itemID and required_skill is primary key.) Now, I'm confused how to create/use this new table. Here are the options that came to my mind: 1) The relationship between Items and Required_skills is one-to-many, so I may create a RequiredSkill class, which belongs_to Item, which in turn has n RequiredSkills. Then I can do Item.get(1).requiredskills. This sounds most logical to me. 2) Since required_skills may well be thought of as constants (since they resemble rules), I may put them into a hash or gdbm database or another sql table and query from there, which I don't prefer. My question is: is there sth like a modelless table in datamapper, where datamapper is responsible from the creation and integrity of the table and allows me to query it in datamapper way, but does not require a class, like I may do it in sql?
