Creates a member function wrapper object, deducing the target type from the template arguments. The wrapper object expects a reference to an object of type T as the first parameter to its operator().
This function and the related types were deprecated in C++11 and removed in C++17 in favor of the more general std::mem_fn and std::bind, both of which create callable adaptor-compatible function objects from member functions.
[edit] Parameters
| f | - | pointer to a member function to create a wrapper for |
|---|
[edit] Return value
A function object wrapping f.
[edit] Exceptions
May throw implementation-defined exceptions.
[edit] Notes
The difference between std::mem_fun and std::mem_fun_ref is that the former produces a function wrapper that expects a pointer to an object, whereas the latter — a reference.
