Can a class inherit a generic class?
Because generic classes can serve as base classes, the same design considerations apply here as with non-generic classes. See the rules about inheriting from generic base classes later in this topic. Whether to implement one or more generic interfaces.
Which object member Cannot be inherited?
What is not possible using Java Class Inheritance? Private members of the superclass are not inherited by the subclass and can only be indirectly accessed. Since constructors and initializer blocks are not members of a Class, they are not inherited by a subclass.
How to create a constraint on a generic class?
To create a constraint on a generic class, after the operator, type where TypeName : followed by the rule that the class must follow. For example, you may want the generic class to implement the functionality of a pre-defined class. You can create the generic class as follows:
How to derive a class from a generic class?
If you have a generic class that can serve as a foundation for another class, you can derive one class from the generic one. To do this, use the formula we apply when deriving a class but follow the name of each class with <>.
Why is there no generic inheritance in C #?
It’s impossible. Using interfaces to describe constraints isn’t an adequate solution once you allow inheritance from type parameters. So that’s another reason why it doesn’t exist in the language today. You’ll need all your possible T’s to implement some interface so that you know that obj.XYZ () makes sense, then you can do
Why do we use generic inheritance in CLR?
The reason is that the CLR likes to be able to compile a single version of the code for MyGenericClass that will work for any reference type specified for T. It can do this for the second case, because it can quietly replace T with object and insert appropriate casts, roughly equivalent to:
