Effect.

After using decorative mode, you can

1) use the arrangement and combination of objects to generate new functions without affecting the feelings of users. And

There are two relative cases of decoration mode: the first case is to use class inheritance to generate new functionality. Because there may be many combinations, many new classes must be generated, which is not flexible enough; another way is to use a list of functional objects to manage various processes, which is flexible enough, but requires the user to be clearly aware of the existence of the list. not transparent.

2) there is no need to pursue accurate design in the early stages of design. In the early stages of design, such as designing base classes, it is not easy to accurately grasp future requirements. For those functions that deal with relatively clear objects, you can consider using decorative mode to assemble the desired functions by the user through the combination of functional objects.

Shortcoming

The flip side of flexibility is trouble. Although each decorator can be combined arbitrarily from the point of view of decoration mode, it is often ordered and required in practical application. This requires users to correctly understand the rules of the use of each decoration class and the details of the implementation of functions, which will increase the burden on users. This disadvantage is particularly prominent when dealing with complex problems.

Applicability

When the processing object is relatively simple, there are many ways to deal with it, and you want these processes to be dynamically combined in a way that is transparent to the user, you can consider using decoration mode.

At this point, I believe you have a deeper understanding of "what are the advantages and disadvantages of using web decoration mode?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
