Some compilers (for languages such as C++) combine namespaces and names for internal use in the compiler in a process called name mangling. As well as its abstract language technical usage as described above, some languages have a specific keyword used for explicit namespace control, amongst other uses. Below is an example of a namespace in C++:
The project namespace or Wikipedia namespace is a namespace consisting of administration pages with information or discussion about Wikipedia. Pages in this namespace will always have the prefix Wikipedia:. They can also be reached by alias WP: or the standard (for any MediaWiki site) prefix Project:. Its namespace number is four (4).
The Objective-C runtime maintains information about the argument and return types of methods. However, this information is not part of the name of the method, and can vary from class to class. Since Objective-C does not support namespaces, there is no need for the mangling of class names (that do appear as symbols in generated binaries).
For example, name resolution in assembly language usually involves only a single simple table lookup, while name resolution in C++ is extremely complicated as it involves: namespaces, which make it possible for an identifier to have different meanings depending on its associated namespace;
The scope resolution operator helps to identify and specify the context to which an identifier refers, particularly by specifying a namespace or class. The specific uses vary across different programming languages with the notions of scoping. In many languages, the scope resolution operator is written ::.
In computer programming, a name collision is the nomenclature problem that occurs when the same variable name is used for different things in two separate areas that are joined, merged, or otherwise go from occupying separate namespaces to sharing one.
Drafts are pages in the Draft namespace (draftspace) where new articles [note 1] can be created and developed, for a limited period of time. [note 2] They allow editors to develop new articles and to receive feedback before being moved to Wikipedia's article namespace (mainspace). If you are logged in, creating a Draft version first is optional.
The term "namespace" is often used to denote a specific type of namespace (e.g., process ID) as well as for a particular space of names. [1] A Linux system begins with a single namespace of each type, used by all processes. Processes can create additional namespaces and can also join different namespaces.
