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! '); /****

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

template ModeProblem ScenarioCoffee and tea are derived from abstract drinks, coffee and tea have the method of boiling water, so you can boil water to extract the method to the abstract beverage to achieve, and coffee with a coffee powder to the cup method, the tea set has a way to add tea to the cup, it looks like two methods are different logic, Abstract classes are referenced in many places by other types, that is, other types call abstract classe

/* Requirements: Gets the time that a program runs. Principle: Get the program start and end time and subtract. Get time: System.currenttimemillis (); When the code is optimized, you can solve this kind of problem. This way, the template method design pattern. What is a template method? When defining a feature, part of the feature is deterministic, but part of it

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.

in speech recognition, the same words are the same person, each time the situation is different, difficult to identify. This chapter is a definition of how to adapt to different situations with different characteristic indicators.1, based on the best path search measure: ① the Bayesian optimality principle and dynamic programming ② editing distance (the edit Distance) ③ in speech recognition dynamic time warp (DTW), speaker-dependentrecognition. Speaker-independentrecognition.2, correlation-base

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.
