• Design pattern for adding / removing elements

  - by de3

  Wikipedia's definition for Iterator pattern design: the Iterator pattern is a design pattern in which iterators are used to access the elements of an aggregate object sequentially without exposing its underlying implementation. Iterator interface in java provides the following methods hasNext() next() remove() Is there a pattern design, or a java interface for inserting / deleting elements, and getting length of the aggregate object, in addition to iterating them? I know remove() is an optional method that can be used once per call to next(), but I am implementing a circular FIFO array and need a method delete() independent of iterator's next().

• How to edit an default Xcode template?

  - by HelloMoon

  When I create an NSObject subclass, I always get an empty implementation. There are some things I always put in my code like pragma marks and -dealloc methods. I prefer to just delete stuff that I don't need over writing it with typos from scratch every time I need it. I need -dealloc and -init almost always, but they don't ship with the default template. Is there a way to customize what's in there?

• In Ruby on Rails, routes.rb, if map.something will create something_path and something_url, does map

  - by Jian Lin

  In Ruby on Rails, routes.rb, if we create a "named route" map.something ":a/:b", :controller => 'foobar' it will also create something_path and something_url which are two methods usable in the controller and in the view. Does map.connect create something like that too? Otherwise, isn't map.connect somewhat disadvantaged in this way? I checked that connect_path and connect_url both aren't created automatically.

• Best way to return result from business layer to presentation layer when using LINQ-to-SQL

  - by samsur

  I have a business layer that has DTOs that are used in the presentation layer. This application uses entity framework. Here is an example of a class called RoleDTO: public class RoleDTO { public Guid RoleId { get; set; } public string RoleName { get; set; } public string RoleDescription { get; set; } public int? OrganizationId { get; set; } } In the BLL I want to have a method that returns a list of DTO. I would like to know which is the better approach: returning IQueryable or list of DTOs. Although I feel that returning IQueryable is not a good idea because the connection needs to be open. Here are the 2 different methods using the different approaches: First approach public class RoleBLL { private servicedeskEntities sde; public RoleBLL() { sde = new servicedeskEntities(); } public IQueryable<RoleDTO> GetAllRoles() { IQueryable<RoleDTO> role = from r in sde.Roles select new RoleDTO() { RoleId = r.RoleID, RoleName = r.RoleName, RoleDescription = r.RoleDescription, OrganizationId = r.OrganizationId }; return role; } Note: in the above method the DataContext is a private attribute and set in the constructor, so that the connection stays opened. Second approach public static List<RoleDTO> GetAllRoles() { List<RoleDTO> roleDTO = new List<RoleDTO>(); using (servicedeskEntities sde = new servicedeskEntities()) { var roles = from pri in sde.Roles select new { pri.RoleID, pri.RoleName, pri.RoleDescription }; //Add the role entites to the DTO list and return. This is necessary as anonymous types can be returned acrosss methods foreach (var item in roles) { RoleDTO roleItem = new RoleDTO(); roleItem.RoleId = item.RoleID; roleItem.RoleDescription = item.RoleDescription; roleItem.RoleName = item.RoleName; roleDTO.Add(roleItem); } return roleDTO; } } Please let me know, if there is a better approach.

• Load a list of localized strings at once in IOS

  - by Victor Ronin

  I want to show a table with the list of strings which are localized. The straightforward method would be: a) Point data source to my ViewController b) Define an array c) Allocate the array in my ViewController and init (arrayWithObjects) it with the strings from localized resources (NSLocalizedString) d) Use this array in UITableViewDataSource delegated methods Mainly my concern is item b). The construction looks quite heavy and I wonder whether I can somehow specify and load whole list of localized string at once.

• Multi-property "transactions" in Core Data / NSManagedObject / NSFetchedResultsController?

  - by Martijn Thé

  Hi, Is it possible to set multiple properties of an NSManagedObject and have the NSFetchedResultsController call controllerDidChangeContent: only once? In other words, is it possible to say something like: [managedObject beginChanges]; [managedObject setPropertyA:@"Foo"]; [managedObject setPropertyB:@"Bar"]; [managedObject commitChanges]; and then have the NSFetchedResultsController call controllerDidChangeContent: (and the other methods) only one time? Thanks!

• Parse string as if it were a querystring in Ruby on Rails

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  I have a string like this: "foo=bar&bar=foo&hello=hi" Does Ruby on Rails provide methods to parse this as if it is a querystring, so I get a hash like this: { :foo => "bar", :bar => "foo", :hello => "hi" } Or must I write it myself? EDIT Please note that the string above is not a real querystring from a URL, but rather a string stored in a cookie from Facebook Connect.

• ASP.NET MVC validation in weakly typed views

  - by Eedoh

  Hello. I have a problem validating data on view that is not strongly typed. I'm updating data from 3 different models on that view, and I have validation methods that work on them, but I don't know how to display the validation message. Where should I put validation messages (on strongly typed views I put them in ModelState, I presume that does not make sense in this case), and how should I display them (I doubt that I will be able to use "validationmessagefor", maybe "validationmessage" somehow)?
