[Boost-users] binary lambda function as a ftor

Hi All,

 

I have defined the following predicate

 

boost::function<bool(map_t::value_type, mxClassID)>
predicate=bind(&map_t::value_type::second, _1) == _2;

 

which behaves as expedted.

// blah is true

bool blah = predicate(std::pair<const string, mxClassID>("foo",id), id);

 

How would I encorporate this into a find_if ? 

 

i.e.

 

map_t::iterator pos2 = find_if(valid_arg_map().lower_bound(cmd), 

                         valid_arg_map().upper_bound(cmd), 

                               ???? predicate ????);

Thanks for any help

 

Sean

Interesting, but swamped by everything that is not BGL. I'll take a  

look as soon as possible... sorry.
