Method: Object#clone

Defined in:

lib/source/ruby.rb

#clone ⇒ Object

call-seq:

obj.clone -> object

Produces a shallow copy of obj – the instance variables of obj are copied, but not the objects they reference. See also the discussion under Object#dup.

class Klass
   attr_accessor :str
end

s1 = Klass.new      #=> #<Klass:100>
s1.str = "Hello"    #=> "Hello"
s2 = s1.clone       #=> #<Klass:101>
s2.str[1,4] = "i"   #=> "i"
s1.str              #=> "Hi"
s2.str              #=> "Hi"

This method may have class-specific behavior. If so, that behavior will be documented under the initialize_copy method of the class.
