class Person
def initialize(name,age)
@name = name
@age = age
end
def name=(name)
@name = name
end
def age=(age)
@age = age
end
def name
@name
end
def age
@age
end
can be written with
class Person
attr_accessor :name, :age
def initialize(name,age)
@name = name
@age = age
end
By using attr_accessor, you will automatically get the setter and getter method. Take note that there are some hashes following it.
If you only want the setter method, go for attr_writer, while the getter method, go for attr_reader.
While it is also possible to use attr :name to get attr_reader, and attr :name, true to get the same effect as attr_accessor, but it looks less readable than the previous ones.
Using setter, the set method becomes similar to variable assignment when it's actually a method call.
