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] It is often used to make existing classes work with others without modifying their source code.
Decorator pattern: decorator object adds its own members, forwarding others to the decorated object. Proxy pattern: proxy object forwards member use to real object. Forwarding may be used in other patterns, but often use is modified; for example, a method call on one object results in several different methods being called on another: Adapter ...
The Decorator Pattern (or an implementation of this design pattern in Python - as the above example) should not be confused with Python Decorators, a language feature of Python. They are different things. Second to the Python Wiki: The Decorator Pattern is a pattern described in the Design Patterns Book.
Decorator pattern: add additional functionality to an object at runtime where subclassing would result in an exponential rise of new classes; Extensibility pattern: a.k.a. Framework - hide complex code behind a simple interface; Facade pattern: create a simplified interface of an existing interface to ease usage for common tasks
A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
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.
In software engineering, the delegation pattern is an object-oriented design pattern that allows object composition to achieve the same code reuse as inheritance.. In delegation, an object handles a request by delegating to a second object (the delegate).
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.
