Facade Pattern

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:

    Symbolism erects a facade of respectability to hide the indecency of dreams.
    Mason Cooley (b. 1927)

    Put out the light, and then put out the light.
    If I quench thee, thou flaming minister,
    I can again thy former light restore
    Should I repent me; but once put out thy light,
    Thou cunning’st pattern of excelling nature,
    I know not where is that Promethean heat
    That can thy light relume.
    William Shakespeare (1564–1616)
