View Full Version : c++ public accessor method
04-19-2012, 10:11 PM
I have three private member variables for a camera class.
float m_FOV, m_Near, m_Far;
Now what I'm trying to create a public accessor method for them. Any ideas??

So you want a method that gets those values? Why not just make 3 public methods that return the float, like:

Generally accessor functions are use to keep the internal structure of the class encapsulated. Considering that fact, I think it should be fine if you simply make your class a struct with those variables.
The reason you would use a struct instead of a class is simply good programming practice. Since a struct is a data structure(a group of data elements under one name).
If you wanted to create one accessor function for all these data elements, you could do it is follows. Although I have not seen it done like this very often, some people like wrapping things up.
void your_class_name::triple_var_accessor_func(float& var1, float& var2, float& var3)
var1 = m_FOV;
var2 = m_Near;
var3 = m_Far;
This is called "passing by reference" in case you are not familiar with it.
