use of inheritance

Because it is a custom component so storyboard we can't use, all the code must be handwritten, so as to ensure the flexibility of the use of components and reduce the coupling between the various components, more conducive to cooperation between the

Why should you use object-oriented programming? Today, we explain why we use object-oriented and what the benefits of it are by talking about a few design principles.A single principle of responsibility:Full name: "Single-responsibility Principle"

definition: the policy mode belongs to the behavior pattern of the object. It is intended for a set of algorithms that encapsulate each algorithm in a separate class with a common interface, so that they can be replaced with each other. The policy

I. Overview　　The Adorner mode dynamically attaches responsibility to the object. To extend functionality, decorators provide an alternative to inheritance. A simple description is a wrapper object that gives the object new behavior.Second, solve the

Turn from the three cornerstones of object-oriented object-oriented three cornerstones (encapsulation, inheritance and composition, polymorphism)One of the three cornerstones of the package1. What is encapsulation?Encapsulation (encapsulation) is

Decorator modeDecorator Mode: A simple understanding is to wrap a layer of attachment action on the original object, and keep the wrapped object in the same class family as the wrapper, but add additional actions specific to the wrapper class.The

Due to their own shortcomings, the inheritance relationship was deducted by experts as "evil" hats. "Use delegated relationships instead of inheritance", "Try to use interface implementations instead of abstract class inheritance" and so on expert

First, object-oriented, what exactly is this object?This object is not an instance of C #, in C # We call an instance of a class an object, which is strictly an object in object-oriented programming implementation (OOP), object-oriented programming,

Object-to-object relationships1. The relationship between objects and objectsDepend onAssociationCombinationIt is often discussed that object-to-object relationships provide two of the following: cohesion, couplingCohesion generally refers to

Through the object-oriented understanding, object-oriented has four characteristics: abstraction, encapsulation, inheritance and polymorphism.What we have come to understand is the most important object-oriented feature inheritance:Inheritance is a

On the Richter scale substitution principle, the OCP, as the high-level principle of OO, advocates the use of "abstract (abstraction)" and "polymorphic (polymorphism)" To change the static structure of the design to the dynamic structure and

Application Scenario Description: if we need to develop a tank for the game, in addition to a variety of different types of tanks, we also hope to add one or more of the following features for it in different occasions, for example, infrared night

Problem:In object-oriented design, abstraction is a very important concept. The so-called abstraction is to ignore the special features of a class of objects and propose some common features, ignoring some details for the moment, changes to such

Today and people gossip in the unintentional mention of the day of the Dragon in the sword, this is an ordinary with a point weak protagonist, character complex. Back after a careful thought, I unexpectedly think his way to the road is quite

Million red envelopes, fiery open!!! Have you more wonderful!I. Subtypes and subclasses Here I want to first mention the difference between the word type (subtype) and the subclass (subclass), simply put, as long as the class A uses the
