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 (a "shim") 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, Façade, and to a lesser extent, Proxy design patterns. == Structure and implementation == The specific way in which a wrapper library is implemented is highly specific to the environment it is being written in and the scenarios which it intends to address. This is especially true in the case when cross language/runtime interoperability is a consideration. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「wrapper library」の詳細全文を読む スポンサード リンク
