Ruby - Self

The "self" method is omitted from the Ruby API documentation. I was able to dig this explanation from one of my Ruby books:

"self" is a reference to the current object instance.

here is an example:

class Leaf
  def print_self
    p self
  end
  def to_s
    "I am a leaf"
  end
end

l = Leaf.new
l.to_s
=> "I am a leaf"
l.print_self
=> I am a leaf
