Suppose a hierarchical structure where B is a parent of C, D
I would like to define a method in B that C, and D will utilize, but it would reference other methods that would be defined in C and D
What is the best approach for that type of structure?
in pseudo code
class B
int login()
parseSite()
class C : B
int parseSite()
site specific logic goes here
class D : B
int parseSite()
site specific logic goes here
What you want is an abstract method, for example:
class abstract B
{
public int login()
{
parseSite();
}
protected abstract void parseSite();
}
class C : B
{
protected override void parseSite()
{
}
}
class D : B
{
protected override void parseSite()
{
}
}
The login() method is inherited in all the descendants of B and calls the parseSite() method which must be implemented in any descendant of B.
Make parseSite method abstract within B and override it in C and D.
