Say I have the following (C++)
class Parent
{
Parent(Foo f){};
}
class Child : public Parent
{
Child(Foo f, Bar b)
: Parent(f)
{};
}
...
// And a whole bunch of other children, all calling Parent constructor
Suppose now I need to add a new parameter to the Parent constructor
Parent(Foo f, Baz z){};
Then I will have to change every single child class to the following
Child(Foo f, Baz z, Bar b)
: Parent(f, z)
{};
Is there anyway I can avoid having to change every single child class?
Guess might be related to this, how to avoid repetitive constructor in children which suggests that I must change every child class.
If so, are there any languages / design patterns that would make such a change less painful?
