I have hierarchy of classes:
class A{}
class B: A {}
class C:B {}
is it possible to implement method in class A and it would be inherited by derived classes B and C and so on and that method should return value of class type?
A val = A.method(); (val is A)
B val = B.method(); (val is B)
C val = C.method(); (val is C)
And I don’t want use of generics in call of this method, ie:
C val = C.method<C>();
Guys, excuse me, one elaboration, this method should be static.
I don’t want to use generic in method istelf, because it forces to point type that method should return, whereas method should return type of its class.
class A
{
Method<T>()
{
T result;
return result;
}
}
If I have such method I can change return type:
D result = A.Method<D>();
but I wanted it to return value of type A;
No, that is not possible.
To call the method like that it would have to be static, and static methods are not inherited.
Using
B.method()to call a static method inAis the same as usingA.method(). The compiler just uses the type to determine where the method is, but it’s impossible for the method to know if it was called using theAorBtype.
