What does this mean "->"?
c++, objective-c, operators
Solution
The -> operator is shorthand for deferencing and then accessing a member.
Given
type *a;
`(*a).b` is equivalent to `a->b`

Problem
Ive almost only programmed in objective-c, for a couple of months ago I programmed a little in box2d and say this "->". Now what does that mean? its cant be objective-c it must be from c++ because box2d is c++, I one time saw someone using it in objective-c code and I just couldn't seem to understand what it did. Google doesn't support non-text characters so its impossible for me to google it since I don't know what it is.
