c++ public accessor method

OpenGL OpenGL: Basic Coding

Hi,

I have three private member variables for a camera class.
Example

float m_FOV, m_Near, m_Far;

Now what I’m trying to create a public accessor method for them. Any ideas??

Thanks

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

 float camera::Get_m_FOV()
{
return m_FOV;
}

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.
