Using Object Oriented Features

Dot notation:

  object.method()
  object.member
  ? object.member
  object.member.method()
  object.member.submember.method()
  ...etc...

You may also get the value of a member's subscript by using the euclass name as the instance:

   ? ClassName.MemberName

This preprocesses to:

   ? ClassName_MEMBER_MemberName

These two would be equivalent:

   ? MyInstance.MemberName
   ? MyInstance[ClassName.MemberName]

In the case where duplicate members have been declared, the last declared member becomes the defaul. The only way to access an earlier declared member is to explicitly subscript it:

    euclass foo( sequence s )
        integer x, y
    end euclass

    euclass bar( foo f )
        integer x
    end euclass

    bar b
    b = {1,2,3}
    ? b.x        -- will print 3 (because .x refers to the bar.x member)
    ? b[foo.x]   -- will print 1
