A wrapper function is a function (another word for a subroutine) in a software library or a computer program whose main purpose is to call a second subroutine [1] or a system call with little or no additional computation. Wrapper functions simplify writing computer programs by abstracting the details of a subroutine's implementation.
Some wrapper libraries exist to act as a bridge between a client application and a library written using an incompatible technology. For instance, a Java application may need to execute a system call. However system calls are typically exposed as C library functions.
[1] [2] Its use began to become popular in the Python community from around 2015. [3] tox acts a wrapper for both virtual environments and test automation tools, to simplify the consistent testing of Python code across a range of environments. [4] It integrates the use of a virtualisation tool, such as virtualenv, with a test script such as ...
In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. [1]
The Simplified Wrapper and Interface Generator (SWIG) is an open-source software tool used to connect computer programs or libraries written in C or C++ with scripting languages such as Lua, Perl, PHP, Python, R, Ruby, Tcl, and other language implementations like C#, Java, JavaScript, Go, D, OCaml, Octave, Scilab and Scheme.
A Java wrapper package [9] A .NET and .NET Framework wrapper package [10] A Python wrapper package [11] OR-Tools supports a wide range of problem types, [12] [3] among them: Assignment problem [13] Linear programming; Mixed-integer programming [14] Constraint programming [6] Vehicle routing problem [13] [15] Network flow algorithms
Python Paste, often simply called paste, is a set of utilities for web development in Python. Paste has been described as "a framework for web frameworks". [1] The Python Paste package contains Python modules that help in implementing WSGI middleware. The package includes a WSGI wrapper for CGI applications. It also includes a simple webserver ...
In both cases, there are two objects, and the first (sending, wrapper) object uses the second (receiving, wrappee) object, for example to call a method. They differ in what self refers to on the receiving object (formally, in the evaluation environment of the method on the receiving object): in delegation it refers to the sending object, while ...
