design patterns explained simply

Behavioral patterns (behavior pattern) involves the assignment of tasks between objects and the algorithm for completing these tasks. It not only describes the object pattern or class design pattern, it also describes the interaction mode between objects or classes. Using this design mode can free programmers from complicated control flows and focus only on inter

OK, all the crap and water are said to be finished, the following began to enter the dry mode.The basic design pattern is divided into three types, a total of 23 kinds.　　Create pattern : Factory method mode, abstract Factory mode, creator mode, prototype mode, Singleton mode.　　Structural mode : Appearance mode, adapter mode, proxy mode, decoration mode, bri

At present, many people simply learn JSP to learn JSP. The basis of Java is very thin, unfortunately. To help you understand the design pattern and understand the application of

design Pattern A book introduces design patterns into the software community, the authors of which are Erich Gamma, Richard Helm, Ralph Johnson and John vlissides (commonly known as "gang"). The core concept behind the design pattern described is very simple. After years of software development practice, Gamma and othe

We recommend that you learn programming when you must look at the algorithm to see how the bottom of the implementation, regardless of learning any language, I believe that design patterns must be well known, this article in the Java language as a representative, explained 23 design

Design patterns are just for the Java architect--at least you've probably always thought so. In fact, design patterns are very useful for everyone. If these tools are not patents for "architecture astronauts", what are they? Why are they very useful in PHP applications? This article explains these problems.

IOS design patterns-(1) Overview There have been a lot of free schedules recently. There is no good idea about iOS apps, so let's just put it down and stop writing it. Spend some time learning the design model. A series of blog posts will be written to record the learning process of design

A framework is a semi-finished product of an application. The framework provides a public structure that can be shared between applications. Developers integrate frameworks into their own applications and expand them to meet their specific needs. The difference between a framework and a toolkit is that the framework provides a consistent structure, not just a set of tool classes. The framework is actually a group of parts for you to choose to complete your own system.

For this issue, if your program is more about performance (such as the kernel), you really shouldn't introduce too many indirect layers, but if your program is more focused on scalability and maintainability, you should consider design patterns.(5) Many programmers in the C + + community are transferred from C or even assembler, so these people are more acc
