  2. Object copying - Wikipedia

    en.wikipedia.org/wiki/Object_copying

    In VBA, an assignment of variables of type Object is a shallow copy, an assignment for all other types (numeric types, String, user defined types, arrays) is a deep copy. So the keyword Set for an assignment signals a shallow copy and the (optional) keyword Let signals a deep copy. There is no built-in method for deep copies of Objects in VBA.

  3. Cloning (programming) - Wikipedia

    en.wikipedia.org/wiki/Cloning_(programming)

    C++ objects in general behave like primitive types, so to copy a C++ object one could use the '=' (assignment) operator. There is a default assignment operator provided for all classes, but its effect may be altered through the use of operator overloading. There are dangers when using this technique (see slicing).

  4. Copy constructor (C++) - Wikipedia

    en.wikipedia.org/wiki/Copy_constructor_(C++)

    These cases are collectively called copy-initialization and are equivalent to: [2] T x = a; It is however, not guaranteed that a copy constructor will be called in these cases, because the C++ Standard allows the compiler to optimize the copy away in certain cases, one example being the return value optimization (sometimes referred to as RVO).

  6. Zero-copy - Wikipedia

    en.wikipedia.org/wiki/Zero-copy

    Zero-copy programming techniques can be used when exchanging data within a user space process (i.e. between two or more threads, etc.) and/or between two or more processes (see also producer–consumer problem) and/or when data has to be accessed / copied / moved inside kernel space or between a user space process and kernel space portions of operating systems (OS).

  7. Copy-on-write - Wikipedia

    en.wikipedia.org/wiki/Copy-on-write

    Copy-on-write (COW), also called implicit sharing [1] or shadowing, [2] is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.

  8. Binary-code compatibility - Wikipedia

    en.wikipedia.org/wiki/Binary-code_compatibility

    Binary-code compatibility (binary compatible or object-code compatible) is a property of a computer system, meaning that it can run the same executable code, typically machine code for a general-purpose computer central processing unit (CPU), that another computer system can run.

  9. Garbage collection (computer science) - Wikipedia

    en.wikipedia.org/wiki/Garbage_collection...

    Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.
