I need a method that creates an empty clone of an object in a base class? For instance: public class ChildClass : ParentClass { public ChildClass() { } } public class ParentClass { public SomeMethod() { // I want to create an instance of the ChildClass here } } Up until now, we have an abstract method defined in t...
I have a class ClassA mapped to TableA. I also have a mapping for it and it has an entity-name of EntityA. Now, I need to create another mapping named EntityATwo between ClassA for TableA, but slightly different. Although I could copy-paste the mapping of EntityA to EntityATwo, it would be very difficult to maintain that. Thus, my q...
I just started reading on Douglas Crockford's "Javascript The Good parts" where he explains about Augmenting basic types. Function.prototype.addMethod=function(name,func) { this.prototype[name]=func; return this; }; The moment after doing this, the addMethod becomes available for all basic objects like String, Number etc. Th...

Hello, I am trying to use the .dll of a slideshow project and inheriting the xaml(from the slideshow prj) in a new project so that I have the xap file needed as source for the Silverlight tag.

I understand that static method inheritance is not supported in C#. I have also read a number of discussions (including here) in which developers claim a need for this functionality, to which the typical response is "if you need static member inheritance, there's a flaw in your design". OK, given that OOP doesn't want me to even think a...
Update: Replaced the destructor example with a straight up method call example. Hi, If I have the following code: class a { public: virtual void func0(); // a has a VTable now void func1(); }; class b : public a { public: void func0() { a::func0(); } void func2(); }; Is there a VTable in B? B has no virtual functio...
I want to have a constructor with an argument that gets inherited by all child classes automatically. But Java won't let me do this class A { A(int x) { /// } } class B extends A { } class C extends A { } #Implicit super constructor A() is undefined for default constructor. I dont want to have to write B(int x) and C(int x) e...

I currently use nhibernate but a guy at work has recently gotten me interested in subsonic again. I really prefer a Poco, domain-driven style approach to development and worry about the database later. It looks like this is partially supported using simplerepository. My question is, how flexible is subsonic in how it generates your da...

I'd like to have multiple versions of an object with different access modifiers on the properties For example I might have a user class- public abstract class UserInfo { internal UserInfo() { } public virtual int ID { get; set; } public virtual string Password { internal get; set; } public virtual string Usernam...
Referring here A is a precompiled Java class (I also have the source file) B is a Java class that I am authoring B extends A. How can logic be implemented such that A can call the methods that B has. The following are the conditions: I don't want to touch A(only as a last option though that is if no other solution exists). I don'...
