I have this small class called City that simply holds some information about a city, here it is: class com.weatherwidget.City { var zipCode:String; var forecastText:Array = new Array(5); } When I have an array of cities and I change one of the forecastText of one city it will change that forecastText for all of the cities. Fo...
I have a 2-dimensional jagged array (though it's always rectangular), which I initialize using the traditional loop: var myArr = new double[rowCount][]; for (int i = 0; i < rowCount; i++) { myArr[i] = new double[colCount]; } I thought maybe some LINQ function would give me an elegant way to do this in one statement. However, the c...
Doesn't object initialization outside of a constructor break encapsulation ? Given: class MyClass { public string _aString; } Shouldn't the _aString member be private and instantiated via a call to the constructor (constructor omitted here): MyClass test = new MyClass("test"); Instead of the alternate method of object in...
Within the same compilation unit, the C++ standard says that static initialization order is well defined -- it's the order of the declarations of the static objects. But using the Sun Studio 12 compiler I'm encountering unintuitive behavior. I've define a templated class helper<T> which contains a static member _data of type T and a stat...
How do I create and initialize an array in F# based on a given record type? Suppose I want to create an Array of 100 record1 records. e.g. type record1 = { value1:string; value2:string } let myArray = Array.init 100 ? But it appears the Array.init does not allow for this, is there a way to do this? Edited to add: Of course I ...
Here is some code outlining a problem I've been wrestling with. The final problem (as far as g++ is concerned at the moment) is that: "error: 'Foo-T' was not declared in this scope" when performing the Bar::Bar(...) constructor routine. Otherwise, the problem I'm attempting to learn my way through is one of setting base-class member type...
If I have the following code: public class MyClass { public string myName { get; private set; } public string myId { get; set; } } A private compiler-generated variable is created for the setter. I want the setter not to be accessible for object initialization only. But, how do I get to initially set the myName variable? Rea...
I found this piece of code on Wikipedia. #include <stdio.h> int main(void) { int c; while (c = getchar(), c != EOF && c != 'x') { switch (c) { case '\n': case '\r': printf ("Newline\n"); break; default: printf ("%c",c); } } return 0; } I'm curious about expression ...
1. I know that it is possible to initialise an array of structures in the declaration. For example: struct BusStruct { string registration_number; string route; }; struct BusStruct BusDepot[] = { { "ED3280", "70" }, { "ED3536", "73" }, { "FP6583", "74A" }, }; If the structure is changed into a class, lik...
Say I have a class with a field that needs to be initialized when the object is initialized. Such as list that need to be created before objects can be added/removed from it. public class MyClass1 { private List<MyOtherClass> _otherClassList; public MyClass1() { this._otherClasslist = new List<MyOtherClass>(); }...
Is it good practice to initialize a global variable in PHP? The snippet of code seems to work fine, but is it better to initialize (in a larger project, say for performance sake) the variable outside of a function, like in the second scratch of code? if(isset($_POST["Return"]))Validate(); function Validate(){ (!empty($_POST["From"])...
I've read in many places that you should always initialize Objective-C objects like so: - (id) init { if (self = [super init]) { .... } return self; } Because the super's init method may return a separate object from the current self. Now I'm trying to do something like this, and I'm not sure if I have it right, v...
So I'm a bit rusty getting back into programming and I can't seem to find a good reference for understanding the structure for what I am trying to achieve. So, without further ado I am looking at creating and Class object such as. #import Assets.h @interface MainRecord: NSObject { Assets* assets; ... } ... @end Having a class...
What's the difference between these two methods of initializing the observers ArrayList. Or any other type for that matter. Is one faster than the other? Or am I missing some other benefit here. class Publisher implements Observerable { private ArrayList observers = new ArrayList(); } class Publisher implements Observerable { ...
Please, help me to create a nested struct with an array. How do I fix this code? class CMain { public: CMain(); ~CMain(); private: struct { CCheckSum() : BufferSize(500) {memset(Buffer, 0, BufferSize);} const int BufferSize; char Buffer[BufferSize]; }Sm...
Can I launch a Java WebStart application with a set of parameters just like an applet is configured with the <param> tags ? Thanks ...
Inside XNA struct Vector2 are two public variables X and Y. I have the following code: Vector2 v; if(b) v.X=1; else v.Y=2; //use v The compiler gives "Use of unassigned local variable 'v'" But it runs correctly nonetheless. Is there a more correct way of doing it? ...
I find in my PHP pages I end up with lines and lines of code that look like this: $my_id = isset($_REQUEST['my_id']) ? $_REQUEST['my_id'] : ''; $another_var = isset($_REQUEST['another_var']) ? $_REQUEST['another_var'] : 42; ... Is there a better, more concise, or more readable way to check this array and assign them to a local variabl...
Hi, I'm learning to develop for iPhone without Interface Builder (a personal preference), and I'm not sure which function of a view controller I should be setting up the view in: init, viewDidLoad, or loadView. I read somewhere to only use init for the view controller, if anything, and not setting up the view as it could cause problems. ...
There doesn't seem to be a standard constructor so I've taken to doing the following void myMethod(char delimiter = ',') { string delimiterString = 'x'; delimiterString[0] = delimiter; // use string version ... } Is there a better way to do this? ...
