Protected that makes a method private, but within the scope of a class rather than within a single object
<![CDATA[
# you can call a protected method from the scope of the methods of any object
# that's a member of the same class:
class Person
def initialize(age)
@age = age
end
def age
@age
end
def age_difference_with(other_person)
(self.age - other_person.age).abs
end
protected :age
end
fred = Person.new(34)
chris = Person.new(25)
puts chris.age_difference_with(fred)
puts chris.age
