Why would you have an abstract base class defining an interface for a library where there is only one (always 开发者_运维知识库and forever) derived class?You may want to swap out the implementation fo
I\'m trying to take advantage of the polymorphism in c++, but I\'m from a c world, and I think what I\'ve done could be done more cleverly in a OOP way.
I was wondering if there could be any way to write a template function in an abstract class, and have it (the template function) automatically instantiated with the type of the derived class?
I want to use unity for a polymorphic event aggregation/handling where handlers are registered through the container.
Question: Create an array of at least four pointers to Reader objects. Use the New operator to create at least four pointers to derived class objects and assign them to the array.
I\'m refactoring some code in project whilst reading Object-Oriented Reengineering Patterns specifically the section on \"Transforming Conditionals to Polymorphism\". So the current code base has cons
My problem is as follows: We have an Algorithm that works internally with Expression-objects that have a \"String getContent()\" method
I am working on a project (Rails 3.0.3) where I think I may need to use STI, but I am not sure if I should just add an extra column to a table and be done with it.
I generally understand interfaces, inheritance and polymorphism, but one thing has me puzzled. In this example, Cat implements IAnimal and of course List implements IList:
I have a superclass called DataItem and it has multiple children and the children have children too. I dynamically set the object type but in the end the type reference is DataItem. Here is the code I
