How do I use Decorator and Flyweight design patterns together?


How do I use Decorator and Flyweight design patterns together?

To fix the issue you can do Design patterns are not "standards". Design patterns are common Appropriate [vs. Anti-patterns] solutions for common problems. And usually you don't build entire system by using certain design pattern. Rather your subsystems in your code are preferably done by some pattern. Even Asp.net MVC is not really a pattern - it is a framework. But while you use it, your business layer can use many different design patterns to achieve its goals. For example, in the system I work on, there are many absolutely untestable areas developed without any patterns in mind. I started to use MVP, so my new code is testable. They live side by side in one system. Go to sourcemaking. It is explained there, when to use which pattern. And remember, that a pattern is just a general direction. Each implementation can be different based on the requirement. Your question is not specific enough to give you a good answer. We can discuss here about Decorator but without knowing what you're doing, this pattern may not be even good for you.

wish help you to fix your issue I generally think of the Decorator as "adding" to some thing, where as Chain of Responsiblity is more like handling something thing.
In comparing the two patterns (besides being apples and oranges) the biggest difference is the Chain of Responsibility can kill the chain at any point.

Hope this helps Structurally, the patterns are very similar. A lot of the difference is in the intent of the pattern and not the way they are built.
The adapter pattern is used to adapt a class with one interface to that of another interface. Typically, the class you are adapting is legacy code or in a library that you can't access (or at least can't change). One key difference with the adapter is that the interface that you are adapting and what you are providing back are different.

it fixes the issue Well, in the sample you posted it isin't that clear, but the abstract class usually takes care of the component encapsulation and the default method implementations are to delegate method calls to that component.
Therefore, when implementing concrete decorators, you would't have to override all methods if you don't need to.

Hope this helps First of all they belong to different categories: Prototype is creational one, Flyweight is structural one.
In Prototype objects' creation go through cloning, it ease object's creation. By making a request for cloning we create new cloned object each time.

hop of those help? In the Julia world the best equivalent seems to be the Memoize package
code :
using Memoize                                                                       
@memoize function x(a)                                           
    println("Computing or constructing a big data structure...")
    (a=a, b=2a)                                          
end
julia> x(7)                                                             
Computing or constructing a big data structure...
(a = 7, b = 14)                                                         

julia> x(7)                                                             
(a = 7, b = 14)
