The merging Reuse Principle is also known as the composition/aggregate Reuse Principle and carp principle. Its definition is as follows: Composite Reuse Principle (CRP): Use object combinations as much as possible instead of inheritance to achieve reuse. The merging Reuse Principle is to use some existing objects in a new object through the association relationship (including the combination

of programming, which conforms to the normal thinking of people. If we drive a Mercedes Benz is dependent on the Mercedes-Benz, the use of laptops directly rely on notebook computers.② "Dependency inversion": programming is to abstract the real world things, and then we based on the needs of the system design to produce a dependency on the abstract, instead of people's traditional thinking of the dependence between things, called "inverted."3.2 Depen

interface injection;That is, in the function declaration, the argument is an abstract class or interface, which implements the transitive dependent object, thus achieving the purpose of directly using the dependent object.can be summarized as interface passing, construction method passing and Setter method is passed. The core of the dependency inversion principle is that we should interface programming, understand interface-

engine does those things. First, try traversing the properties in B, but not the Name property. The request to find the name attribute is delegated to the prototype of the constructor of object B, which is b.__proto__ logged and points to B.prototype, and B. The prototype is set to an object created through new A (). The name attribute is still not found in the

I have been working for three years. To be honest, I have never studied object-oriented.ProgramDesign, but some emotional understanding in some work plus some so-called theory. Reading a book 《 Head first object-oriented design and analysis " , The story in the book vividly describes OOA D I would like to take this op

I recently read the design model. I like this book very much, and the content is also very understandable. I am a little addicted to reading it. Haha, I first looked at the object-oriented basics. I have been familiar with object-oriented basics before, I have a further unde

(Do not reverse-rely on inverted errors, such as the design of the logical layer and the UI, you are in the logical class of the process relies on the interface of the UI layer an

About the Great software:"Great software is always doing what the customer wants him to do," says the client-friendly program designer . As a result, customers will be able to pay the desired results even when they have a whim to use the software in new ways.The object-oriented programmer says: great software is object-orient
