first, what is AOP?AOP: Aspect-oriented programming, he is a programming paradigm that provides a different perspective to consider program structure to improve object-oriented programming. Second, the function of AOPin the system development process will have some common features, this is the object-oriented vertical thinking method can solve the problem, this time, AOP horizontal extension can solve these public service weaving system. AOP can encapsulate the logic or responsibility, such as

WPF arrows and wpf arrows Some time ago, the WPF arrows were used for work, after reference to Using WPF to Visualize a Graph with Circular Dependencies. Write a WPF arrow library. First, The main class relationships are as follows: (Image Excerpt from Go to the Shape Definition and find a virtual method. // Summary: // Gets a value that represents the System. w

There is a number of spherical balloons spread in two-dimensional space. For each balloon, provided input is the start and end coordinates of the horizontal diameter. Since It's horizontal, y-coordinates don ' t matter and hence the x-coordinates of start and end of the diameter suffice. Start is always smaller than end. There'll is at the most 104 balloons.An arrow can is shot up exactly vertically from different points along the x-axis. A balloon with Xstart and xend bursts to an arrow shot at

Two annoying problems are often encountered in Visio painting. One is automatic deformation when the two arrows are at the intersection, and the other is that when the text is near the arrow when the text is added to the flowchart, automatic arrows rearranging: Cross deformation of two teaching Headers The comment is close to the arrow and the arrow is automatically re-painted. Solution: 1. Sel

The difference between div > span and div span is that there are arrows and no arrowsdiv > SpanSpan is the next level of a div's relationshipIn this case, the span element is found:But this situation is not found.A div span with no arrows between the elements can find span in both cases, as the span element at all levels below the div can be found.

Decorative mode is also known as packaging (Wrapper) mode. Adornment mode extends the functionality of the object transparently to the client, and is an alternative to the inheritance relationship.structure of the decoration mode　　Decorating mode dynamically attaches more responsibility to an object in a transparent manner to the customer. In other words, the client does not feel that the object is different before and after decorating. Adornment mode

Original: C # design pattern of eight decorative mode (Decorator pattern) "Structural type"First, IntroductionToday we are going to talk about the third mode of the "structural" design pattern, which is "decoration mode", English name: Decorator pattern. The first time I saw this name came to mind is another word "decoration", I said I say to the "decoration" understanding it, we must see clearly, is "decoration", not "decoration". We grow up, to get

, will cause the expansion of the class, and finally, will be submerged in the class of the sea; At this time, I do not need to say, you are not reminded of the bridge mode, bridging mode is to adapt to the changes in multiple dimensions of the sub-class "Explosion" situation, However, bridging patterns are designed to accommodate different abstractions and implementations, and do not apply to what I'm talking about here. So what is the good, this is about the summary of the decoration model tod

software system. What does this mean?First, let's take a look at the absence of AOP. In a conventional object-oriented system, how to deal with such common functions is to extract these functions and then call them wherever necessary, just draw the public module that calls General logs. If it is similar to other modules, do not draw them, as shown in Figure 8: Figure 8 call Public Functions It is clear that the application module actively calls the public module, that is, the application mod

This is simply a decorative pattern, because the pattern is not well understood. Can't write a deeper piece of content for the time being.What is decorative mode? To draw up a scene where one needs to dress up, we can write a person class, define n methods for it, wear short sleeves, wear leather shoes, and so on. To add a new decoration, we add a new method to the person class, but this violates the "metho

Adornment mode extends the functionality of the object transparently to the client, in other words, the client does not feel that the object is different before and after decorating. Adornment mode extends objects without the use of creating more subclasses. is an alternative to an inheritance relationship.(a) A brief picture of the decorative pattern:(ii) Environmental role of

Decorative Mode (Decorator) is to dynamically add some additional responsibilities to an object, and in addition, the decoration mode is more flexible than the generation of subclasses.The structure diagram is as follows:Component is to define an object interface that can dynamically add responsibility to these objects.
