Template Method Mode: defines the skeleton of an algorithm in one method, and delays some steps into subclasses. The template method allows subclasses to redefine some of the steps in the algorithm without changing the structure of the algorithm.This pattern is primarily used to create an algorithm template.Hollywood principles: Don't Call (call) us, we'll call (
Template Method Pattern (templates mode) Applet detailedThis address: Http://blog.csdn.net/caroline_wendyReference Template Method pattern: http://blog.csdn.net/caroline_wendy/article/details/32159455Template Method Pattern, the applet is a small program that can be executed
String. The pattern of the template is a regular expression that can be defined by overriding pattern attributes and defining new regular expressions.
For example, using the new delimiter "{{", use {{var}} as the variable syntax.

Template Pattern Definition: Defines the skeleton of an algorithm in an operation, delaying execution of some steps into its subclasses.
In fact, Java abstract class is template mode, so the use is very common. And it's easy to understand and use, let's start with an example:
Copy Code code as follows:
Public abstract class Benchmark

In the book "Java and Patterns" of Dr. Shanhong, this describes the template method pattern: The template method pattern is the behavior pattern of the class. Prepare an abstract class, implement some of the logic in the form of concrete methods and concrete constructors, a
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 m
of the implementation of the module is fixed, but for each step of the specific implementation is not fixed. How do you usually do this kind of demand? From the design pattern point of view, this design pattern is called the template method pattern, you may not know the name of the design

The template method pattern is the behavior pattern of the class. Prepare an abstract class, implement some of the logic in the form of concrete methods and concrete constructors, and then declare some abstract methods
1. An example of a template methodThis section focuses on the template method pattern in design mode. Let's take a look at an example: what would you do if the boss asked you to make a model of a car and ask for the basic functionality to be done, regardless of extensibility? We will first design a class diagram based on experience:From this class diagram, it is
The template method pattern of the Java design Pattern defines the framework of an operation's algorithm, and delays some steps into subclasses so that subclasses can redefine certain steps in the algorithm without altering the structure of the algorithm . belong to behavior class pattern
As shown in the following ill
Template method pattern, is a very simple design pattern, we may often use in the real development, but we do not realize that this is a design pattern. First, consider the definition of the template method pattern:

The template method pattern is defined as:
The skeleton or step of an algorithm is defined in a method, and some steps are deferred to subclasses to implement. Template methods allow subclasses to redefine some of the steps in an algorithm without changing the structure of the algorithm.The template method defines the

Template method mode is also called template mode, which defines the skeleton of an algorithm in one method, and delays some steps into subclasses. The template method allows subclasses to redefine some of the steps in the algorithm without changing the structure of the algorithm.

Introduction and implementation:
The structure of the strategy mode is very simple, more simple than the template method mode, it is essentially a principle of embodiment, to the low-said is the principle of the "in-the-way", the high-said is the dependency inversion principle, the concrete implementation process is this:
There is an interface (abstract class) in a that has an abstract algorithm method a
There is a set of int
So that the development and maintenance of web systems more convenient, thereby effectively saving human and material resources, by more and more enterprises of the green squint.
The template engine is an important method of the MVC pattern establishment process, the developer can design a set of meaning tags, through the Technical analysis processing effective data logic processing from the interface
