Re: [boost] For inclusion to boost::function

(repost, I accidentally posted this to boost::build list ... ugh).

I have written code to solve this problem:

I have class foo, like so:

class foo { boost::function<void (foo *)> func_ptr;

void call() { func_ptr(this); } };

I want func_ptr to be either a free-standing function (or class static), OR a class member function of a derived class, so:

void bar(foo *f) { ... }

OR:

class baz : public foo { public: baz() { func_ptr = &baz::doit; }

void doit() { } };

The obvious problem with the latter is that it needs to be downcast implicitly, and some kind of exception thrown if the wrong type is passed.

I think this is what Boost.Bind is for. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
