Can I write functors using a private nested struct?
- by Kristo
Given this class:
class C
{
private:
struct Foo
{
int key1, key2, value;
};
std::vector<Foo> fooList;
};
The idea here is that fooList can be indexed by either key1 or key2 of the Foo struct. I'm trying to write functors to pass to std::find so I can look up items in fooList by each key. But I can't get them to compile because Foo is private within the class (it's not part of C's interface). Is there a way to do this without exposing Foo to the rest of the world?
(note: I've got to run to a meeting. I'll be able to post more sample code in about a half hour.)
