[Boost-users] Boost.lambda

Can anyone explain why the class member functions need their address taken
when used in a boost::lambda::bind inside the class?

 

e.g.

vector<int> v;

MyClass theClass;

for_each(v.begin(), v.end(), 

bind(MyClass::DoSomething, &theClass, _1));

 

//The above compiles fine, but.

 

class MyClass {

public:

            void DoSomething(const int& i) { . }

            void Go()

{ 

for_each(myInts.begin(), myInts.end(), 

/*--------------------->*/         bind(MyClass::DoSomething, this, _1));

}

            vector<int> myInts;

};

 

The above code does not compile.  The marked line needs to be:

bind(&MyClass::DoSomething, this, _1));

Why?

Thanks.
