Composite pattern represents the hierarchy of a group of objects in a tree structure. The client can treat a single object and list/group of objects the same way, so it becomes easy for the client. This article describes Composite pattern implementation in PHP.
Compsite pattern enables a single object and a list of objects to operate the same way. That way the client does not need to know if it is using a single object or a list, while using it. So the usage becomes simple in that case. This article describes Composite pattern implementation in TypeScript.
Using Composite pattern we can make an object and a group of objects, behave the same way. The client will not know any difference between an object and object group/list while using it. This article demonstrates Composite pattern implementations in GoLang.
Composite pattern is used to handle the operation of a bunch of classes (having the same interface), to operate the same function of all items a the same time. Using Composite pattern the client can ignore the difference between the Composition and Leaf classes, and can use the composition considering the same interface. This article demonstrates Composite pattern implementations in Java. Check the following examples.
When there is a bunch of classes that are of the same type (implement the same interface), and we need to use them as composition (not as individual objects), we can use Composite pattern. Composite pattern helps to use the classes in a composition, so that the client can use the composition and individual classes can be tread in the same way.
