Description
Structural design patterns are concerned with how to assemble objects and classes into larger structures, keeping the structures flexible and efficient.
Here is a list of structural design pattern types.
| Design Pattern | Description |
| Adaptor | Allows objects with incompatible interfaces to collaborate. |
| Bridge | Lets us split a large class or a set of closely related classes into two separate hierarchies (abstraction and implementation), which can be developed independently of each other. |
| Composite | Lets us compose objects into tree structures and then work with these structures as if they were individual objects. |
| Decorator | Lets us attach new behaviors to objects by placing these objects inside special wrapper objects that contain the behaviors. |
| Facade | Provides a simplified interface to a library, a framework, or any other complex set of classes. |
| Flyweight | Lets us fit more objects into the available amount of RAM by sharing common parts of the state between multiple objects instead of keeping all of the data in each object. |
| Proxy | Lets us provide a substitute or placeholder for another object. A proxy controls access to the original object, allowing you to perform something either before or after the request gets through to the original object. |
Overall
We now know structural design patterns and their types.
