Perfectly! What you can say about following pieces of code:
std::vector vec;
std::for_each(vec.begin(), vec.end(),
std::bind(&std::shared_ptr<SomeClass>::get, std::placeholders::_1,
std::bind(&SomeClass::foo, std::placeholders::_1, 10)));
and
vector vec;
for_each(vec.begin(), vec.end(), bind(&shared_ptr<SomeClass>::get, _1,
bind(&SomeClass::foo, _1, 10)));
Here's what I do, for every class that's put in shared_ptr's (I'm very
disciplined in this way):
// SomeClassFwd.h:
class SomeClass;
typedef std::shared_ptr<SomeClass> SomeClassPtr;
typedef std::vector<SomeClassPtr> SomeClassCollection;
Now, your code becomes:
SomeClassCollection vec;
std::for_each(vec.begin(),
vec.end(),
std::bind(&SomeClassPtr::get,
std::placeholders::_1,
std::bind(&SomeClass::foo, std::placeholders::_1,
10)));
I would agree C++ can be very verbose. Using typedef can limit this a lot
though.
