Structural patterns

Structural patterns deal with class and object composition. Using interfaces or abstract classes and methods, they define ways to compose objects, which in turn obtain new functionality. The following is a list of patterns we categorize as structural patterns:

Adapter
Bridge
Composite
Decorator
Facade
Flyweight
Proxy

Note

See https://en.wikipedia.org/wiki/Structural_pattern for more information about structural design patterns.

Adapter pattern

The adapter pattern allows the interface of an existing class to be used from another interface, basically, helping two incompatible interfaces to work together by converting the interface of one class into an interface expected by another class.

The following is an example of adapter pattern implementation: ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.
