voucher design template

The so-called template method mode defines an algorithm framework in the abstract base class, and the steps in the framework are implemented by the derived classes. The benefit of the template method mode is that operations with the same code are upgraded to abstract base classes, and only differentiated code is implemented in the derived classes, thus minimizing the existence of duplicate code. Note that t

Template Method Mode Definition: defines the skeleton of an algorithm in an operation, and delays some steps to the subclass. The template method allows the subclass to redefine certain steps of an algorithm without changing the structure of an algorithm. For example, the exam copied by student A and student B is very similar. Except for different answers, the other questions are the same. If the instructor

I. Application scenarios When an algorithm flow a () is designed in our code, the algorithm flow depends on several other flows B (), c (), d (), and so on, in addition, the dependency processes B (), c (), and d () in the system may be implemented in a variety of ways. At this time, we can use the method template mode. For the moment, we have implemented this design model. Let's discuss its advantages.Ii.

2018-05-06Template Method Design patternThe skeleton of an algorithm in an operation is defined in a method of the parent class, and some steps are deferred to the subclass because the implementation details of the different subclasses are different. The template method allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Abstract Parent class: de

. We continue to supplement the various subsequent additions based on the original code, and our code becomes unsightly under the new if statement line. Of course, as programmers, we don't have much of a say in demand, and there's nothing we can do about it. But we can do our best to design the architecture of the program, let us write the code more extensibility, so that we can deal with a variety of requirements changes. Below you will use the

[C ++ design mode] template method mode Template mode: defines the algorithm skeleton in an operation and delays some steps to the subclass. According to the example in headfirst design mode, the algorithm framework (process) of tea and coffee is the same, but some algorithms are implemented differently, and some are t

Template Methodology Design pattern (Templete method)Defines an algorithm skeleton in an operation, and delays the implementation of some mutable parts into subclasses.The template method design pattern allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.1 I

The template method mode, I personally think, is still a design model that is more useful, and is also a more studious and understandable. We will continue to understand it by simulating a scenario. Now let's take a look at the tea process. First, we need to boil a pot of water, then put tea in the teapot, add the boiling water, and wait for the tea to soak. After the previous two discussions, you should ha
