In Strategy pattern, a class behavior or its algorithm can be changed at run time. This type of design pattern comes under behavior pattern.In Strategy pattern, we create objects which represent various strategies and a context object whose behavior varies as per its strategy object. The ...

an algorithm uses data that clients shouldn't know about. Use the Strategy pattern to avoid exposing complex, algorithm-specific data structures. a class defines many behaviors, and these appear as multiple conditional statements in its operations. Instead of many conditionals, move related conditional...
在strategy pattern中,為了讓各strategy能方便存取原來物件的所有public member function,我們常用*this將整個物件傳給各strategy,這樣的設計並沒有什麼不好,但各strategy和原物件過於tight coupling,導致各strategy難以再和其他各物件搭配,本文使用template解決此問題。 在(原創) 我的Design Pattern之旅:Strategy ...
在(原創) 我的Design Pattern之旅[1]:使用template改進Strategy Pattern (高級) (Design Pattern) (C++) (OO C++) (Template C++)中,使用了C++的template改進strategy pattern,本文使用C#
Strategy design pattern helps to choose a specific implementation of algorithm or task in run time – out of multiple other implementations for same task.
In many patterns, the class that holds information used by the main participants in the pattern is called a context (we could have used one in Interpreter, remember?). In our case, the document class acting as the context, and is pretty simple: ...
Strategy has 2 different implementations, the first is similar to State. The difference is in binding times (Strategy is a bind-once pattern, whereas State is more dynamic). Strategy objects often make good Flyweights. 22 design patterns and 8 principles explained in depth...
