|
* Binders turn functions/functors with two arguments into functors
|
|
|
|
* with a single argument, storing an argument to be applied later.
|
|
|
|
* For example, a variable @c B of type @c binder1st is constructed
|
|
|
|
* from a functor @c f and an argument @c x. Later, B's @c
|
|
|
|
* operator() is called with a single argument @c y. The return
|
|
|
|
* value is the value of @c f(x,y). @c B can be @a called with
|
|
|
|
* various arguments (y1, y2, ...) and will in turn call @c
|
|
|
|
* f(x,y1), @c f(x,y2), ...

|
|
|
*
|
2010-02-04 19:20:34 +01:00
|
|
|
* The function @c bind1st is provided to save some typing. It takes the
|
2007-10-29 22:13:23 +01:00
|
|
|
* function and an argument as parameters, and returns an instance of
|
|
|
|
* @c binder1st.
|
|
|
|
*
|
|
|
|
* The type @c binder2nd and its creator function @c bind2nd do the same
|
|
|
|
* thing, but the stored argument is passed as the second parameter instead
|
2011-11-20 22:14:56 +01:00
|
|
|
* of the first, e.g., @c bind2nd(std::minus<float>(),1.3) will create a
|
2007-10-29 22:13:23 +01:00
|
|
|
* functor whose @c operator() accepts a floating-point number, subtracts
|
2010-02-04 19:20:34 +01:00
|
|
|
* 1.3 from it, and returns the result. (If @c bind1st had been used,
|
|
|
|
* the functor would perform <em>1.3 - x</em> instead.
|
2007-10-29 22:13:23 +01:00
|
|
|
*
|
|
|
|
* Creator-wrapper functions like @c bind1st are intended to be used in
|
2010-02-04 19:20:34 +01:00
|
|
|
* calling algorithms. Their return values will be temporary objects.
|
2007-10-29 22:13:23 +01:00
|
|
|
* (The goal is to not require you to type names like
|
|
|
|
* @c std::binder1st<std::plus<int>> for declaring a variable to hold the
|
2011-11-20 22:14:56 +01:00
|
|
|
* return value from @c bind1st(std::plus<int>(),5).
|
2007-10-29 22:13:23 +01:00
|
|
|
*
|
|
|
|
* These become more useful when combined with the composition functions.
|
|
|
|
*
|
2011-11-20 22:14:56 +01:00
|
|
|
* These functions are deprecated in C++11 and can be replaced by
|
|
|
|
* @c std::bind (or @c std::tr1::bind) which is more powerful and flexible,
|
|
|
|
* supporting functions with any number of arguments. Uses of @c bind1st
|
|
|
|
* can be replaced by @c std::bind(f, x, std::placeholders::_1) and
|
|
|
|
* @c bind2nd by @c std::bind(f, std::placeholders::_1, x).
