Una funzione' oggetto è qualsiasi oggetto per cui è definito l'operatore chiamata di funzione. C + + fornisce numerose funzionalità incorporate in oggetti funzione, nonché di sostegno per la creazione e la manipolazione di oggetti funzione nuovi.

Original:

A function object is any object for which the function call operator is defined. C++ provides many built-in function objects as well as support for creation and manipulation of new function objects.
