nested-class

Available nested classes SuperView and NestedView. class SuperView : UIImageView { class NestedView : UIImageView { var text : String = "Nested View" } var text : String = "Super View" var nested : NestedView? } I would like to set for a UIImageView the property named "Custom Class Name" to value "NestedView" inside the inspector of the storyboard scene. But the Interface Builder couldn't find "NestedView" class. At this time, I think that Interface Builder only recognizes the names of Objective-C classes. You can still make Interface Builder find a nested class with the @objc keyword: class

Given what I know of every other type of static feature of programming––I would think the answer is 'no'. However, seeing statements like OuterClass.StaticNestedClass nestedObject = new OuterClass.StaticNestedClass(); makes me wonder. polygenelubricants Yes, there is nothing in the semantics of a static nested type that would stop you from doing that. This snippet runs fine. public class MultipleNested { static class Nested { } public static void main(String[] args) { for (int i = 0; i < 100; i++) { new Nested(); } } } See also public static interface Map.Entry<K,V> public static class

The current class library I am working on will have a base class (Field) with over 50 specific "field" types which will inherit from "Field" and nested for maintain readability. For example... abstract class Field { public int Length { get; set; } public class FieldA : Field { public static void DoSomething() { Console.WriteLine("Did something."); } } } So far everything looks good and I can use the code as shown: class Program { static void Main(string[] args) { Field.FieldA.DoSomething(); } } However, why does this work as well? What is going on here that allows the compiler / IDE

I have made these 2 classes to make use of the concept of anonymous inner class. Class 1 has a static inner class. And class 2 uses it. But i cant understand how to call the method of the inner class. Please help me out. Class 1 public class outerclass { outerclass() { System.out.println("Constructor of new class"); } public void showthis(String str) { System.out.println(str); } static class insideclass { insideclass() { System.out.println("This is inside class constructor"); } public void nowshowthis(String str) { System.out.println(str); } } } Class 2 public class helloworld { public static

I have a class A, which has a nested class B. Class A, will create n(run time parameter) instances of class B. In the constructor of A, after computations that need to be made at run time, I compute a size, let's say s. Now, every class B, will hold an array of size s. However, I am not allowed to use .cpp files and all the work must be done in header files. This means, as far as I understand, that I can not use these approach (with static ): class B { static const int s; int a[s]; }; So, I decided to use enum , but I couldn't make it work (even with enum class of C++11). The idea is that you

I have seen many questions about accessing private members of an enclosing class. However, my question is the opposite. If I have (as an example), the following code: public class A { private String outerString = "silly string"; static class B { private final A someA = new A(); public void foo() { String b = someA.outerString ; } } } I'm wondering why this compiles? I would have expected an error by virtue of the way in which I am accessing the 'outerString' instance variable from class A (via someA.outerString). I know that an inner class can access the enclosing class members directly by an

The code below will find intersection of 2 lines and return the point object. If point is only ever going to be created by IntersectionOf2Lines class, should i make point a nested class ? If not then why not ? Thanks class Point { private final int x; private final int y; public Point(int x, int y) { this.x = x; this.y = y; } int getX() { return x; } int getY() { return y; } } public class IntersectionOf2Lines { public static Point calculateIntersection(Line line1, Line line2) { int x = (line2.getConstant() - line1.getConstant()) / (line1.getSlope() - line2.getSlope()); int y = line1.getSlope(

Is declaring a class that extends Activity inside another Activity class possible? If it is, how would I register that class in the manifest? Also, is that something that can be reasonably done or is it a bad idea? I was thinking of something like class ListClass extends ListActivity{ ... ArrayList items; class ItemClass extends Activity{ ... Item item; @Override onCreate(){ Integer pos = getIntent().getExtras().getInt("pos"); item = items.get(pos); } } @Override onItemClick(int position){ startActivity(new Intent(this, ItemClass.class).putExtra("pos", position)); } } Note the syntax isn't 100
