Function Objects

Метки: python

In Advanced C++:Programming Styles And Idioms (Addison-Wesley, 1992), Jim Coplien coins the term functor which is an object whose sole purpose is to encapsulate a function (since “functor” has a meaning in mathematics, in this book I shall use the more explicit term function object). The point is to decouple the choice of function to be called from the site where that function is called.

This term is mentioned but not used in Design Patterns. However, the theme of the function object is repeated in a number of patterns in that book.
