Void safety (also known as null safety) is a guarantee within an object-oriented programming language that no object references will have null or void values. In object-oriented languages, access to objects is achieved through references (or, equivalently, pointers). A typical call is of the form: x.f(a, ...) where f denotes an operation and x denotes a reference to some object. At execution time, however, a reference can be void (or null). In such cases, the call above will be a void call, leading to a run-time exception, often resulting in abnormal termination of the program.

Void safety is a static (compile-time) guarantee that a void call will never arise. (en)
  • Void safety (anche nota come null safety) è una garanzia che viene posta nei linguaggi orientati agli oggetti per garantire che nessun riferimento a oggetto abbia un puntatore nullo (o void). Nei linguaggi orientati agli oggetti, l'accesso agli oggetti e ottenuto tramite riferimenti (o, in modo equivalente, puntatori). Una chiamata tipica è qualcosa nella forma: x.f(a, ...) dove f denota un'operazione e x denota un riferimento a qualche oggetto. Durante l'esecuzione, tuttavia, un riferimento può essere void o null ("nullo" in italiano). In questi casi, la chiamata diventa una void call (chiamata "vuota" o "null"), portando a un'eccezione a run-time, causando spesso una terminazione inattesa del programma. Void (o null) safety è una garanzia (a compile-time) che permette di verificare che una chiamata nulla (o void) non venga mai effettuata. (it)
