Wrapper Library

Wrapper Library

In computer programming, a library is a collection of subroutines or classes used to develop software. Libraries expose interfaces which clients of the library use to execute library routines. Wrapper libraries (or library wrappers) consist of a thin layer of code which translates a library's existing interface into a compatible interface. This is done for several reasons:

  • To refine a poorly designed or complicated interface.
  • Allow code to work together which otherwise cannot (e.g. Incompatible data formats).
  • Enable cross language and/or runtime interoperability.

Wrapper libraries are implemented using the Adapter, Fa├žade, and to a lesser extent, Proxy design patterns.

Famous quotes containing the word library:

    With sighs more lunar than bronchial,
    Howbeit eluding fallopian diagnosis,
    She simpers into the tribal library and reads
    That Keats died of tuberculosis . . .
    Allen Tate (1899–1979)
