instance method

BasicObject#send

(::interned name, *untyped, **untyped) ?{ (?) -> untyped } -> untyped

foo.send(symbol [, args...]) → obj

foo.__send__(symbol [, args...]) → obj

foo.send(string [, args...]) → obj

foo.__send__(string [, args...]) → obj

VALUE
rb_f_send(int argc, VALUE *argv, VALUE recv)
{
    return send_internal_kw(argc, argv, recv, CALL_FCALL);
}

Invokes the method identified by symbol, passing it any arguments specified. When the method is identified by a string, the string is converted to a symbol.

BasicObject implements __send__, Kernel implements send. __send__ is safer than send when obj has the same method name like Socket. See also public_send.

Example

class Klass
  def hello(*args)
    "Hello " + args.join(' ')
  end
end
k = Klass.new
k.send :hello, "gentle", "readers"   #=> "Hello gentle readers"
