• How do I unit test the methods in a method object?

  - by Sancho

  I've performed the "Replace Method with Method Object" refactoring described by Beck. Now, I have a class with a "run()" method and a bunch of member functions that decompose the computation into smaller units. How do I test those member functions? My first idea is that my unit tests be basically copies of the "run()" method (with different initializations), but with assertions between each call to the member functions to check the state of the computation. (I'm using Python and the unittest module.)

• How to convert string to XML object in JavaScript?

  - by Jack Roscoe

  Hi, I am aware of this question already existing, but it has given me no luck. I have an application which loads a physicial XML document via the following method: jQuery.ajax( { type: "GET", url: fileName, dataType: "xml", success: function(data) { etc... I parse the XML and convert it into a string which is saved into a variable so that it can easily be stored in a database. How can I now convert the data in this variable back into an XML object so that it can be parsed as such?

• Why is the compiler not complaining about an additional ',' in Array or Object Initializers?

  - by Danvil

  Using simple type like class A { public int X, Y; } with object intializers, one can write var a = new A { X=0, Y=0 }; But the following is also accepted by the compiler: var a = new A { X=0, Y=0, }; // notice the additional ',' Same for int[] v = new int[] { 1, 2, }; This looks a bit strange ... Did they forgot to reject the additional ',' in the compiler or is there a deeper meaning behind this?

• Do I have to call release on an objective-c retain class variable when setting it to a new object?

  - by Andrew Arrow

  Say I have: @property (nonatomic,retain) NSString *foo; in some class. And I call: myclass.foo = [NSString stringWithString:@"string1"]; myclass.foo = [NSString stringWithString:@"string2"]; Should I have called [myclass.foo release] before setting it to "string2" to avoid a memory leak? Or the fact that nothing is pointing to the first "string1" object anymore is good enough? And in the dealloc method [foo release] will be called.

• How can you databind a single object in .NET ?

  - by Tomas Pajonk

  I would like to use a component that exposes the datasource property, but instead of supplying the datasource with whole list of objects, I would like to use only simple object. Is there any way to do this ? The mentioned component is DevExpress.XtraDataLayout.DataLayoutControl - this is fairly irrelevant to the question though.

• Can two managed object context share one single persistent store coordinator?

  - by mystify

  Example: I have one persistent store coordinator which uses one single persistent store. Now there are two managed object contexts, and both want to use the same persistent store. Could both simply use the same persistent store coordinator, or would I have to create two instances of NSPersistentStoreCoordinator? And if I had to, then: Would I also have to create two NSPersistentStore instances?

• Why is NULL/0 an illegal memory location for an object?

  - by aioobe

  I understand the purpose of the NULL constant in C/C++, and I understand that it needs to be represented some way internally. My question is: Is there some fundamental reason why the 0-address would be an invalid memory-location for an object in C/C++? Or are we in theory "wasting" one byte of memory due to this reservation?

• What is the easiest to transfer an object between two C# apps over the web?

  - by edude05

  I have written an application that basically gathers up a bunch of text and numerical data from the client PC and stores it as an object. Right now I'm implementing XML serialization so that the file can be saved. The issue is now, how do I get this data to the server? I have a server running IIS 7 setup but I don't quite understand the ASP.net life cycle, so I'm not sure how to implement the receiving app. What should I do? Thanks

• It is good programming practice to always check for null pointers before using an object in C++?

  - by jm1234567890

  This seems like a lot of work; to check for null each time an object is used. I have been advised that it is a good idea to check for null pointers so you don't have to spend time looking for where segmentation faults occur. Just wondering what the community here thinks?

• Why cast null before checking if object is equal to null?

  - by jacerhea

  I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

• How can I move an object left and right with silverlight?

  - by Craig

  I currently have two buttons that say left and right, and I want them to move a square object left and right respectively. What its currently doing when i press left is moving the square to the left, and if I press left again, it resets from the center and goes left. I want it so that when I press left, from where ever it is currently to go left and right. I know the principle is something like get current objects position and add the canvas coordinates respectively but how do I do this?

• What is a good way to ensure the background of a flash object matches the page?

  - by George Edison

  Since there is no way that you can make the flash object transparent, there needs to be some other means by which you can match the background. I thought of maybe creating a ActionScript/Javascript bridge, but I wonder if this is the route to take. Do I have a better option?

• .NET immutable object usage best practices? Should I be using them as much as possible?

  - by Daniel

  Say I have a simple object such as class Something { public int SomeInt { get; set; } } I have read that using immutable objects are faster and a better means of using business objects? If this is so, should i strive to make all my objects as such: class ImmutableSomething { public int SomeInt { get { return m_someInt; } } private int m_someInt = 0; public void ChangeSomeInt(int newValue) { m_someInt = newvalue; } } What do you reckon?

• Is there a Pattern in Scala that add a method to an Array object?

  Is there a Pattern in Scala that can add a method to an Array object? I am thinking of the implicit conversion of Int to RichInt. But that can't be done as Array is a final class.

A::do_lengthy_work(a);
