Flyweight Design Pattern – Definition. Flyweight is a structural design pattern that lets you fit more objects into the available amount of RAM by sharing common parts of state between multiple objects instead of keeping all of the data in each object. The other part which varies from object to object will still be part of final object. Large numbers of objects should be supported efficiently. Problem. There is a game application which has the game player to … Use sharing to support large numbers of fine-grained objects efficiently. The Flyweight design pattern is one of the twenty-three well-known GoF design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse. The Flyweight pattern is a structural design pattern. GitHub is where the world builds software. It can help save system resources. Some programs require a large number of objects that have some shared state among them. It is a technique to minimizes memory footprint by sharing or avoiding redundancy as much as possible with other similar objects. Flyweight pattern tries to reuse already existing similar kind objects by storing them and creates a new object when no matching object is found. The flyweight design pattern allows to greatly reduce memory footprint of any product by dividing an object into basically two parts. If multple objects have some internal part as common then all these objects can share these memory to reduce memory consumption. The Flyweight design pattern is a structural design pattern commonly used when we want to group similar data for multiple objects. Flyweight Design Pattern is a Structural Design Pattern that concerned with space optimization. Game application example. Flyweight gains this agility by minimizing memory and computational usage by sharing and reusing objects. The fog lifts, revealing a majestic old growth forest. The flyweight design pattern, named after the boxing weight class of the same name, is intended to be just as agile and adaptive as those nimble athletes. The Flyweight design pattern reduces the amount of memory required to create a number of large objects of the identical type in an application. But when you’re dealing with large scale systems, the Flyweight Pattern is something to consider. Consider for example a game of war, were there is a large number of soldier objects; a soldier object maintain the graphical representation of a soldier, soldier behavior such as motion, and firing weapons, in addition soldier’s health and location on the war terrain. It is defined as follows: Use sharing to support large number of fine-grained objects efficiently. In this article, I would like to share what is Flyweight Design Pattern and how is it work? Ancient hemlocks, countless in number, tower over you forming a cathedral of greenery. The stained glass canopy of leaves fragments the sunlight into golden shafts of mist. Overview. Flyweight Design Pattern Intent. The flyweight pattern might appear complex to some, and I agree it is one of the lesser used design patterns. Its probably used even less as computers have become more and more powerful. The Motif GUI strategy of replacing heavy-weight widgets with light-weight gadgets. Flyweight Design Pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. The primary intent of this pattern is to store common data for multiple objects in a single place and hence optimise for memory usage. Flyweight Pattern Motivation. Flyweight Game Programming Patterns Design Patterns Revisited. What problems can the Flyweight design pattern solve?
