The facade pattern (or façade pattern) is a software design pattern commonly used with object-oriented programming. The name is by analogy to an architectural facade.
A facade is an object that provides a simplified interface to a larger body of code, such as a class library. A facade can:
- make a software library easier to use, understand and test, since the facade has convenient methods for common tasks;
- make the library more readable, for the same reason;
- reduce dependencies of outside code on the inner workings of a library, since most code uses the facade, thus allowing more flexibility in developing the system;
- wrap a poorly designed collection of APIs with a single well-designed API (as per task needs).
Famous quotes containing the words facade and/or pattern:

“We took advantage of [the Indians’] ignorance and inexperience to incline them the more easily toward treachery, lewdness, avarice, and every sort of inhumanity and cruelty, after the example and pattern of our ways.”
