I do not know what the reason is always the prototype model and template method of mixing, really very distressed ah. Do not know whether we have the same trouble, some words of treatment, no words of prevention AH. Therefore this article carries on the detailed comparison study. prototype Mode The so-called prototype pattern : Specifies the kind of object created with the prototype instance, and creates a

The intent of the template method mode:Defining the skeleton of an algorithm in an operation, Templatemethod allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm. That is, the parent class has defined the process of the algorithm, and the subclass only needs to change the implementation of some of these steps.Just like we're going to put things in the freezer, a complete set of processes is

a concrete class does not need all the methods.Naming rulesNaming rules are one of the channels by which designers communicate, and using proper naming conventions can help communicate between different designers.The name of the hook method should begin with do, which is a standard practice for Java developers who are familiar with design patterns. In the above example, the Hook method Hookmethod () should start with do, and in the HttpServlet class, this naming convention, such as Doget (), Do

The model was originally proposed for machine pattern recognition and was later used to explain human pattern recognition.Its core idea is that in the long-time memory of human beings, there are many kinds of pocket copies of the external patterns that have been formed in life in the past. These pocket copies, called Templates, have a one-to-one correspondence with the external

Template Method Mode description Definition: Defines the skeleton of the method operation, extends some concrete implementations into subclasses, and uses specific implementations that do not affect the skeleton's behavioral steps!

Scene Customers to the bank to handle business: Queue number Specific cash/transfer/Corporate/personal/financial Services Scoring for Bank staff Core:The code that handles a process already has it, but the code for one of the nodes is temporarily uncertain. Therefore, we use the factory method pattern, which transfers the code implementation of this node to the subclass completion.That is, the process step is defined in the p

Cognition is a process of associating an unknown with a known one. For a complex visual system, multiple expressions of input and other knowledge coexist. Perception is the process of combining visual input with existing expressions, and identification and needs to establish or discover the relationship between various internal expressions. Matching is the technology and process of establishing these connections. The purpose of establishing a connection is to explain the unknown with known infor

Stencil ModeAlso called a template method pattern, a skeleton of an algorithm is defined in a method, and some steps are deferred to subclasses.

Template method enables subclasses to redefine certain steps of the algorithm without altering the structure of an algorithm.

In this way, the sort method of the array can be used to sort any class object that implements comparable.Do you think the

C + + Template programming implements Haskell's function pattern matching feature [figure]:The great god Bartosz Milewski wrote an article in 2009, "What Does Haskell has to does with C + +?", using C + + to implement some of the features of Haskell's functional programming language.
