In the following code, I create a base abstract class Base. I want all the classes that inherit from Base to provide the name property, so I made this property an @abstractmethod. Then I created a subclass of Base, called Base_1, which is meant to supply some functionality, but still remain abstract. There is no … Read more
I was wondering if there was any way in JavaScript to loop through an object like so. for(var i in myObject) { // … } But get the name of each property like this. for(var i in myObject) { separateObj[myObject[i].name] = myObject[i]; } I can’t seem to find anything like it on Google. They say … Read more
With this simple class I am getting the compiler warning Attempting to modify/access x within its own setter/getter and when I use it like this: var p: point = Point() p.x = 12 I get an EXC_BAD_ACCESS. How can I do this without explicit backing ivars? class Point { var x: Int { set { … Read more
I have a list of key/value pairs of configuration values I want to store as Java property files, and later load and iterate through. Questions: Do I need to store the file in the same package as the class which will load them, or is there any specific location where it should be placed? Does … Read more
I have two classes, Shape and Square class Shape { var numberOfSides = 0 var name: String init(name:String) { self.name = name } func simpleDescription() -> String { return “A shape with \(numberOfSides) sides.” } } class Square: Shape { var sideLength: Double init(sideLength:Double, name:String) { super.init(name:name) // Error here self.sideLength = sideLength numberOfSides = … Read more
(See below solution I created using the answer I accepted) I’m trying to improve the maintainability of some code involving reflection. The app has a .NET Remoting interface exposing (among other things) a method called Execute for accessing parts of the app not included in its published remote interface. Here is how the app designates … Read more
In the following blog: http://weblogs.asp.net/scottgu/archive/2010/07/16/code-first-development-with-entity-framework-4.aspx The blog contains the following code sample: public class Dinner { public int DinnerID { get; set; } public string Title { get; set; } public DateTime EventDate { get; set; } public string Address { get; set; } public string HostedBy { get; set; } public virtual ICollection<RSVP> RSVPs … Read more
After starting to work with React.js, it seems like props are intended to be static (passed in from the parent component), while state changes based upon events. However, I noticed in the docs a reference to componentWillReceiveProps, which specifically includes this example: componentWillReceiveProps: function(nextProps) { this.setState({ likesIncreasing: nextProps.likeCount > this.props.likeCount }); } This seems to … Read more
Is there any sort of “not in” operator in JavaScript to check if a property does not exist in an object? I couldn’t find anything about this around Google or Stack Overflow. Here’s a small snippet of code I’m working on where I need this kind of functionality: var tutorTimes = {}; $(checked).each(function(idx){ id = … Read more
The goal is to create a mock class which behaves like a db resultset. So for example, if a database query returns, using a dict expression, {‘ab’:100, ‘cd’:200}, then I would like to see: >>> dummy.ab 100 At first I thought maybe I could do it this way: ks = [‘ab’, ‘cd’] vs = [12, … Read more
