Java Design Pattern cainiao series (10) template method pattern modeling and implementation Template Method: defines the skeleton of an algorithm in a Method, and delays some steps to the subclass. The template method allows the subclass to redefine some steps in the algorithm without changing the algorithm structure

I like writing tutorials in blog posts. There are few people who are interested in specific project design schemes, and their ideas are not necessarily clear. It is hard to write blogs, the author is also a little lazy, which is basically a waste of text. Even so, I still want to write about the module design of a project I have done-the template engine of CMS. H

class extension. As long as the extension method in the implementation class passes the unit test, the overall function is generally not big error if the template method is correct.Advantages and application scenarios of the template methodEasy to expand. In general, the template method in the abstract class is not easy to reverse the change of the part, and the

The template method pattern is a very simple pattern because it uses only the inheritance relationship.Template Method Mode: Defines the skeleton of an algorithm in an operation, and extends some of the steps into subclasses. Enables subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Let's look at the structure of this simple pattern:1) Abstract class: Defines one or more abstract methods for spe

Applicable Scenariosin some classes of algorithms, the same method is used, resulting in code duplication. control subclass extensions, subclasses must adhere to algorithmic rules. disadvantage Each different implementation needs to define a subclass, which leads to an increase in the number of classes and a more abstract design. Advantages The Template method pattern removes duplicate code from sub
