download the complete source code for the inference and exhaustion methods.1. The idea of the exhaustive method is very simple: traverse all possible solutions (called the solution space in this article) without constraints, check all constraints one by one until a solution that meets the requirements is found. The key to achieving the exhaustive method is: how to traverse the solution space? In other words, we need to enumerate all possible solutions in a certain order. The solution of "Who ra

principle: multi-purpose combination, less inheritance, or inheritance, should not be used at all? In fact, data abstraction, inheritance, encapsulation, and polymorphism are the most important features of object-oriented language. Inheritance should not be abused. It does not mean that inheritance should not be used at all. In the GoF book, the vast majority of patterns are converted from inherited implementations to object-based combinations and aggregation. The template method mode is one of

is more flexible than the subclass generation function. Enhances the performance of the class to be considered without changing the interface. When to use: 1) You need to expand the functions of a class or add additional responsibilities to a class. 2) You need to dynamically add functions to an object. These functions can be dynamically revoked. 3) A large number of functions are generated by adding basic functions and combinations to make inheritance unrealistic. 3. role composition L Compon

Web Services suddenly got hot, especially M $. net describes a world of interconnection and sharing for us. In fact, these bright prospects have been predicted before the birth of Java, but the ideal implementation process is always rugged and long.Let's look at how Web Services work from an application:There is a Coffee Break, the boss of a Coffee chain store, who wants to expand his own

When you want to add functions or attributes to an existing class, you may first want to use inheritance. Inheritance can add additional functions to the class at the compilation stage, but using inheritance will generate some questions about creating too many classes, maintenance, and update: A classic example of coffee: A coffee program has an abstract coffee c

Customers can need any kind of coffee, we can adjust according to range. You might say, wait a minute, what if I just need coffee and milk? This is going to be a little tricky: def c = new Coffee() def m = new Milk() m.types = ['Coffee','Milk'] (c..m).each{ println it.description() } The trouble is that we can't use

Definition: The template method mode defines an algorithm skeleton in a method, and delays some steps to the subclass. The template method allows the subclass to keep the algorithm structure unchanged, redefines some steps in the algorithm. Hook definition: A hook is a method declared in an abstract class, but it only has null or default implementations. The existence of hooks allows subclass to hook different points of algorithms. If you do not need a hook, The subclass determines it. Scenario:
