Re: [Boost-users] [bind] for_each, Member function question.

I think it is better to pass the value as const reference to Save instead copying it. On 9/13/07, David Klein wrote:

I have a question for boost:binders out there... In the following scenario..(pseudocode)

Class Fred { typedef std::map MyMap;

MyMap Bert;

Save(MyMap::iterator pos) { ... }

SaveAll() { for_each(Bert.begin(), Bert.end(), bind(&Fred::Save, this, _1); }

};

The code wants to save all the data in the map. The bind, I was hoping, would simply call Save for all items in the map, passing in the iterator as the parameter, but I get a template compile fault on the bind. I've tried all sorts of combinations, checked boost docs, read the chapter in Beyond the C++ standard library, Googled etc, but just cannot figure out what I need to do here.

Any help gratefully received.

Hi James,

Class Fred { ...

void // void was missing Save(MyMap::value_type pos) // changed iterator to value_type { ... }

void // void was missing SaveAll() { for_each(Bert.begin(), Bert.end(), bind(&Fred::Save, this, _1); }

};
