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!

Turn http://www.jellythink.com/archives/407In Gof's design model: The basics of reusable object-oriented software, the template method pattern is said to define an algorithmic skeleton in an operation, while delaying some steps into subclasses. Templatemethod allows subclasses to redefine some specific steps of the algorithm without changing the interface of an algorithm.I'll combine this
Stencil ModeAlso called a template method pattern, a skeleton of an algorithm is defined in a method, and some steps are deferred to subclasses. The template method allows subclasses to redefine some of the steps in the algorithm without changing the attaining of the algorithm structure.Examples of our use of brewed coffee and brewing teaProcessing Flow:Coffee Br
Abstract
Template method I learned the second pattern, which is a very easy to understand pattern, but very practical.
Intent
For operation, only the outline of the algorithm is defined first, and some steps are left to the subcategory to fill, so that the subcategories go through some steps without changing the overall architecture of the algorithms.
Its UML
First, the definitionTemplate method Pattern: Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. The template method allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Explanation: Simply speaking, you need to define a common base class, but different operations in the base class, so the
Design Mode: Template Pattern-conversion, templatepatternTemplate Mode
The template method mode defines the skeleton of an algorithm in a method, and delays some steps to the subclass. The template method allows subclass to redefine some steps in the algorithm without changing the algorithm structure.

There is something this morning, come back to take a rest in the afternoon, and then begin to learn. Today is actually the STL vector, not simple to see Ah, with who do not, to own hands to practice a, but to the present has not been realized, tomorrow himself to do a vector bar, today is mainly to see the code of others, and analyzed a bit, In fact, sometimes the analysis and design of the link is more important than the actual writing code.Later in the evening continue our design
Template method Mode:defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. This pattern allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm. Usage scenarios:1, one-time implementation of an invariant part of the algorithm, and the variable behavior left to the subclass to achieve. 2 . The public behavior of
Template mode
The template design pattern creates an abstract object that implements a set of methods that the subclass typically uses as a template for its own design.
Design Scenarios
Typically used for database abstraction classes.
Code Design:
[PHP]
if (!defined (' is_initphp ')) exit (' Access denied! ');
/****
Template method Pattern: Defines the skeleton of an algorithm in one method and delays some steps into subclasses. The template method allows subclasses to be redefined without changing the structure of the algorithm. Redefine some of the steps in the algorithm.

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:
Define The ske
The core idea of the template method pattern is to move the invariant behavior to the superclass and remove the duplicated code in the subclass to reflect its advantages. In fact, the template method pattern is to provide a good code reuse platform.
First, let's take a quick look at the definition:
template method determines their sequencing, but it allows the application and document subclasses to change these steps to meet their needs. 3. Applicability one-time implementation of the invariant part of the algorithm, the variable part to the subclass implementation of the common behavior of each subclass should be extracted and centralized into the parent class to avoid the extension of the code repeating subclass by the parent class control 4.

Template templates Schema Definition:Defines the skeleton of an algorithm in an operation, delaying execution of some steps into its subclasses. With Java's abstract classes, it is often used in template mode, so template mode usage is common. And it's easy to understand and use.
