Wrapper

A wrapper can refer to several things:

*In computer science:

a wrapper is a piece of Computer program which is combined with another piece of code to determine how the latter code is executed.

*:The wrapper acts as an interface between its caller and the wrapped code. This may be done for compatibility, e.g. if the wrapped code is in a different programming language or uses different calling conventions, for security, e.g. to prevent the calling program from executing certain functions, to provide a level of emulation, e.g. a DirectX API which hides the functions of the video card driver. The implication is that the wrapped code can only be accessed via the wrapper. **In the Java programming language a wrapper class is one of eight classes provided in the java.lang packages in Java to provide object-oriented programming Method (computer science) for the eight primitive types. *In packaging, a wrapper is a flat sheet made out of paper, cellophane or plastic which is folded or vacuum sealed to enclose an object and protect it from wear and tear. *In clothing, a wrapper (clothing) is a woman s at-home garment worn over nightwear or lingerie for warmth and modesty (chiefly U.K.; in the U.S. generally now called a robe or bathrobe.)
