Application scenarios:Raw data is tightly coupled with usage
For example:
var products = [("computer",10000,200),("book",10,2000)] func calculateAllStock(products: [(String,Int,Int)]) -> Int { return products.reduce(0, { (total, product) -> Int in return total + product.1*prod
Description: Defines an algorithm skeleton in an operation, delaying some of the steps into subclasses. Prepare a draw template, implement part of the logic, and then declare some common abstract methods that require different implementations for subclasses.
Scenario: For multiple businesses, many functions in their business are similar, and some functions need to be implemented on their own. This allows us to use
OverviewIn real life, a lot of things include a few implementation steps, such as dinner, no matter what to eat, usually contains a list of orders, eat, pay a few steps, usually the order of these steps is: Order –> eat –> pay. In these three steps, the order and the bill are the same, the biggest difference is the second step-what to eat? Eating noodles and eating feast can be very different, 1 shows:In software development, there are sometimes similar situations where a method implementation r

Mode motiveTemplate method pattern is a basic technique based on inheritance, and the structure and usage of template method pattern are also the core of object-oriented design. In the template method pattern, you can put the same code in the parent class and put different method implementations in different subclasses.In the
Introduction to Template Method Patterns Template method, as the name implies, is the general process of doing some tasks. If there are many self-introduction templates on the Web, the recommendation template, that is, the beginning and end of the content may be similar, and in the middle of the need for customers to modify the use.
called, the difference here is only the difference in the function name, and the function does not change anything. Below is the test case of our refactored code and the result of the run. As you see from the results, the output of the test cases that we did not use the template method with are consistent. This is what we've often mentioned in the Refactoring series blog to change the structure inside the code without changing the interface that the
distributed across different classes, it is very inconvenient to maintain.
Flexible. Because of the hook method, the implementation of sub-classes can also affect the operation of the main logic in the parent class. However, while being flexible, child classes affect the parent class and violate the Lee's replacement principle, which also brings risks to the program. This has higher requirements on the design of abstract classes.

Since it is filled, make sure two points. One is that the filled object cannot confuse the disorder, and the second is that the order of the padding cannot be faulted.
This template is injected as a third-party jar dependency, so you must circumvent any business factors.
