The Eiffel class ANY contains features for shallow and deep copying and cloning of objects. All Eiffel classes inherit from ANY, so these features are available within all classes, and are applicable both to reference and expanded objects. The copy feature effects a shallow, field-by-field copy from one object to another. In this case no new ...
Let F be a C-valued sheaf on a topological space X. Fix a point x in X. The open neighborhoods of x form a directed set ordered by inclusion (U ≤ V if and only if U contains V). The corresponding direct system is (F(U), r U,V) where r is the restriction map. The direct limit of this system is called the stalk of F at x, denoted F x.
The term assembly (as in .NET languages like C#, F# or Visual Basic .NET) or package (as in Dart, Go or Java) is sometimes used instead of module.In other implementations, these are distinct concepts; in Python a package is a collection of modules, while in Java 9 the introduction of the new module concept (a collection of packages with enhanced access control) was implemented.
Another loophole [11] applies both to C and C++. Specifically, the languages dictate that member pointers and references are "shallow" with respect to the const-ness of their owners – that is, a containing object that is const has all const members except that member pointees (and referees) are still mutable. To illustrate, consider this C++ ...
The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]

An object type (termed a "class" in other object-oriented languages) is introduced with the OBJECT declaration, which has essentially the same syntax as a RECORD declaration, although an object type is a reference type, whereas RECORDs in Modula-3 are not (similar to structs in C). Exported types are usually named T by convention, and create a ...
In algebra, given a ring R, the category of left modules over R is the category whose objects are all left modules over R and whose morphisms are all module homomorphisms between left R-modules. For example, when R is the ring of integers Z, it is the same thing as the category of abelian groups. The category of right modules is defined in a ...
