Hi,

Is there any way of providing read only access to an array? (problem shown by code below).

class A

  def initialize
    @dependencies = []
  end

  # intended to be read only access
  def dependencies
    @dependencies
  end

  def addDependency(d)
    @dependencies << d
    puts "adding #{d}"
  end
end


a = A.new
a.addDependency("foo")
a.dependencies << "bar" # encapsulation subverted

puts a.dependencies   # foo and bar both in array


Any suggestions appreciated,
James
