Hi,
I'm looking for you input on whats the best practice for public fields
in a class.
In other high level languages (such as C#) it usually exist a property
get/set mechanism. I have seen implementatons using get/set methods
for reteriving and setting private values in a c++ class, which i find
totally okay for primitives as int, strings etc.
One thing that I don't know how to handle is where a class have one or
several class instances inside itself (as private fields) but should
be accessable from public.
Ofcource you could have the get/set methods but then you have to get
and set the complete internal state of the class, where it's very
probably that you only would like to change one single field.
What is the best practice to solve this? Is it okay to have publci
fields in a c++ class without get/set methods?
I could of cource implement a get function that returnes a pointer to
the class, and via that pointer I could change the internal state on
the second class. If my explanation is messy consider this code (semi
pseduo)
class Address
{
public:
string getCity();
string setCity(string const &city);
int getId();
void setId(int const &id);
private:
string name;
int id;
};
class Order
{
public:
/*
what to do here? implement get/set functions for the fields below,
or it it okay to declare the payer and shipto members here?
*/
private:
Address payer;
Address shipto;
};
