it possible have type in parent class subclass overwrites? the idea here have shape class, subclasses of rectangles, square, circles, etc. wondering if it's possible overwrite definition of 'shapetype' int property in parent class. this? e.g. in globals.h #define kshapetype_rectangle = 1 #define kshapetype_square = 2 #define kshapetype_triskaidecagon = 13 // try pronouncing this! in shape.h @interface shape : nsobject @property int shapetype; @property int shapeid; @property uicolor shapecolor; @end .... in rectangle.h #import globals.h @interface rectangle : shape @property static (nonatomic, readonly) int shapetype = kshapetype_rectangle; // how working? @end so 2 questions: 1) such thing possible - i.e. redeclaration of parent property static variable 2) yes or no (1), best coding style sort of thing? i'm not experienced in obj-c patterns, if 1 exists, suggest source me @ please? thanks lot! there no concept of objec...

i having issue polymorphism in c#. have object implements interface, cannot represent collection of objects collection of interfaces. flies in face of understanding of polymorphism. wondering have gone wrong. [testfixture] class tester { [test] public void polymorphism() { var list = new list<foo> {new foo {name = "item"}}; assert.that(list, is.instanceof<ilist>()); assert.that(list[0], is.instanceof<foo>()); assert.that(list[0], is.instanceof<ibar>()); // why rest true false? assert.that(list, is.instanceof<ilist<ibar>>()); } } internal interface ibar { } internal class foo : ibar { public string name { get; set; } } this question of variance, not polymorphism. if list-of-foo ilist-of-ibar, following work: class : ibar {} ilist<ibar> list = new list<foo>(); list.add(new another()); then we've added list of foo. error. compiler stopp...

instead of overloading function 100 times or creating 100 different comparers different types i've decided check type within 1 function. for example i'm using default comparer compare values of set of types (primitives , strings) within 2 objects. contains following code: public class defcomparer : icomparer<object> { public int compare(object a, object b) { .... // = a.gettype().getfield(field).getvalue(a); - not important question i'm showing a&b below different references switch (a.gettype().name) { case "byte": if ((byte)a == (byte)b) return 0; else if ((byte)a > (byte)b) return 1; else return -1; case "uint16": if ((ushort)a == (ushort)b) return 0; else if ((ushort)a > (ushort)b) return 1; else return -1; case "sbyte": if ((sbyte)a == (sbyte)b) return...
