instantiation

Do static variables have the same or similar functionality in C# as they do in C++? Edit: With C++ you can use static variables in many different contexts - such as: 1) Global variables, 2) Local function variables, 3) Class members - Would similar usages in C# behave similar to that of C++? Static has multiple meanings in C++. Static variables in C# basically only have a single meaning: variables scoped to a type. In C#, static on a type is used to denote a type-scoped variable. Static on a method is a type-scoped method. Static can also be used on a class to denote that the entire class is

Is a new (or different) instance of TestCase object is used to run each test method in a JUnit test case? Or one instance is reused for all the tests? public class MyTest extends TestCase { public void testSomething() { ... } public void testSomethingElse() { ... } } While running this test, how many instances of MyTest class is created? If possible, provide a link to a document or source code where I can verify the behaviour. I couldn't find a clear answer in the JUnit docs about your question, but the intent, as anjanb wrote, is that each test is independent of the others, so a new TestCase

I'm trying to implement a basic object-oriented ANSI C runtime and using Objective-C as a guide. They're seems to be three parts. A Class Description, Class Interface, and Class Implementation. In order for the Class Interface to be instantiated, the familiar method of using the Class object to instantiate one's object can only happen if the runtime has already instantiated your class object using the class description. So are all Class definitions allocated statically at first run to provide the ability to instantiate using the Class object? Or if they are allocated dynamically (on initial

I have a generic class in java defined as: public static class KeyCountMap<T> { private Map<T, MutableInt> map = new LinkedHashMap<T, MutableInt>(); // ... rest of the properties... public KeyCountMap() { } @SuppressWarnings({ "unchecked", "rawtypes" }) public KeyCountMap(Class<? extends Map> mapType) throws InstantiationException, IllegalAccessException { map = mapType.newInstance(); } //... rest of the methods... } I have defined same class in .NET as: public static class KeyCountMap<T> { private Dictionary<T, MutableInt> map = new Dictionary<T, MutableInt>(); // ... rest of properties...

In my iPhone app I'm overriding the touchesBegan:withEvent method in my view and what I want to do is make some tweaks to the UITouch object found in the NSSet and send it to another view. I couldn't find anywhere how to create a UITouch object. The way I got it to work was by categorizing the UITouch and create an init method. This blog should explain how to do it: http://cocoawithlove.com/2008/10/synthesizing-touch-event-on-iphone.html 来源： https://stackoverflow.com/questions/1943521/creating-a-uitouch-object
