Facade Pattern - Usage

Usage

An adapter is used when the wrapper must respect a particular interface and must support polymorphic behavior. A decorator allows you to add or alter behavior of an interface at run-time. On the other hand, a facade is used when one wants an easier or simpler interface.

Pattern Intent
Adapter Converts one interface to another so that it matches what the client is expecting
Decorator Dynamically adds responsibility to the interface by wrapping the original code
Facade Provides a simplified interface

Famous quotes containing the word usage:

    Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.
    Fran Lebowitz (b. 1951)

    ...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.
    Kenneth G. Wilson (b. 1923)

    I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.
    —A.J. (Alfred Jules)
