Behavioral patterns (behavior pattern) involves the assignment of tasks between objects and the algorithm for completing these tasks. It not only describes the object pattern or class design pattern, it also describes the interaction mode between

Discussion on Pattern Recognition Technology(1) ------ Introduction In the field of Artificial Intelligence (Artificial Intelligence), Pattern Recognition is perhaps the most challenging technology. Pattern Recognition is also called classification

Public key system and distributed environment requirements Vision Wang) 2009-02-10 Summary As a continuation of the first version of "Design Patterns-engineering implementation and expansion based on C #", we plan to launch the security design

definition: encapsulates operations that act on elements of a data structure, and it can define new operations that function on these elements without altering the data structure.Type: behavior class patternclass Diagram: Example:For example,

Summary The single case pattern is one of the simplest design patterns, but for Java developers, it has many drawbacks. In this month's column, David Geary explores the single case pattern and how to deal with these flaws in the face of

Design pattern (Patterns) --the foundation of reusable object-oriented software Design patterns are a set of repeated use, most people know, through the classification of purpose, code design experience Summary. Design patterns are used in order

Intent The intent of a Null Object is to encapsulate the absence of an object by providing a substitutable alternative that offers suitable default do nothing behavior. In short, a design where "nothing will come of nothing" Use the Null Object

Intent Represent an operation to be performed med on the elements of an object structure. Visitor lets you define a new operation without changing the classes of the elements on which it operates. The classic technique for recovering lost type
