// Adaptor function objects: pointers to member functions.

|
|
// There are a total of 16 = 2^4 function objects in this family.
|
|
// (1) Member functions taking no arguments vs member functions taking
|
|
// one argument.
|
|
// (2) Call through pointer vs call through reference.
|
|
// (3) Member function with void return type vs member function with
|
|
// non-void return type.
|
|
// (4) Const vs non-const member function.
|
|
|
|
// Note that choice (3) is nothing more than a workaround: according
|
|
// to the draft, compilers should handle void and non-void the same way.
|
|
// This feature is not yet widely implemented, though. You can only use
|
|
// member functions returning void if your compiler supports partial
|
|
// specialization.
|
|
|
|
// All of this complexity is in the function objects themselves. You can
|
|
// ignore it by using the helper function mem_fun and mem_fun_ref,
|
|
// which create whichever type of adaptor is appropriate.
|
|
// (mem_fun1 and mem_fun1_ref are no longer part of the C++ standard,
|
|
// but they are provided for backward compatibility.)
