I need to find out some differences between Prototype D.P and Flyweight D.P. I know that the basic difference is that the former makes deep copy. Whereas the letter makes shared object. My lecture...

From the chapter on FlyWeight Pattern inside Gang of Four the FlyWeight pattern is applicable when most object state can be made extrinsic. What does extrinsic state mean ? I get the feeling that...

Does the implementation of Java's String memory pool follows flyweight pattern? Why I have this doubt is, I see that there is no extrinsic state involved in Intern. In GoF I read that there should...

Intent: The intent of this pattern is to use sharing to support a large number of objects that have part of their internal state in common where the other part of state can vary. Objects c...

I start to learn design-patterns. I understand that prototype is for making an exact copy of an object I already have and Flyweight is for making similar objects. I've programmed 2D platformer gam...

I read about Flyweight design pattern and got to know that it stores the objects that can be shared so as to save on heap usage. Java cache also saves the objects that can be reused later so as to ...

In my understanding the purpose of the flyweight pattern is to decrease memory footprint and increase performance by sharing common, extrinsic state. Why would anyone prefer to implement the patter...

To my understanding, the flyweight design pattern is not so different from the factory or singleton design patterns. It is just a factory that produces immutable (and pooled) objects. It is just a...

My application is multithreaded with intensive String processing. We are experiencing excessive memory consumption and profiling has demonstrated that this is due to String data. I think that memor...

I cannot see any single difference between Multiton and Flyweight patterns. Please explain what is the difference?

I am trying to create a flyweight object in Java. I've worked with a similar concept in Objective-C (Singleton Classes in Objective-C // I believe they are the same thing). I am trying to find a t...

I am trying to do the following: boost::unordered_map<boost::flyweight<std::string>, boost::flyweight<std::string> > map; boost::flyweight<std::string> foo(name); map[fo...

I'm working on a problem where I'm instantiating many instances of an object. Most of the time the instantiated objects are identical. To reduce memory overhead, I'd like to have all the identical ...

As far as I know the object pool is a creational pattern and the flyweight is a structural pattern, but actually I can´t see very much difference between the two. Could someone please explain to me...

Maybe there is a simple way around this that I'm not seeing, so hopefully somebody can explain it to me. Let's say I have a class: class A { public: const double parameter; const std::string n...

I've been looking for a flyweight pattern implementation and gave up after reaching page 20 of Google search. While there are countless stupid examples out there, it seems no one has ever pub...

Strings are already using Flyweight Design Pattern. Will it be beneficial/performant to pool common String objects. As the Strings will be already pulled from the String pool?

If you have two instances of a String, and they are equal, in Java they will share the same memory. How is this implemented under the hood? EDIT: My application uses a large number of String objec...

What is the difference between Builder Pattern and Flyweight Pattern in terms of usage, as both of them deals with large number of objects?

I seem to be mentally stuck in a Flyweight pattern dilemma. First, let's say I have a disposable type DisposableFiddle and a factory FiddleFactory: public interface DisposableFiddle : IDisposable...

This is its definition: Use sharing to support large numbers of fine-grained objects efficiently. But I can't figure out what it means exactly. Can you elaborate with a tiny demo?

Is there a way to use Flyweight objects with the hibernating persistence mapping? My data model contains many objects that will be the same. Instead of having a separate instance for each of those ...
