Object#public_send

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

obj.public_send(symbol [, args...]) → obj

obj.public_send(string [, args...]) → obj

static VALUE
rb_f_public_send(int argc, VALUE *argv, VALUE recv)
{
    return send_internal_kw(argc, argv, recv, CALL_PUBLIC);
}

Invokes the method identified by symbol, passing it any arguments specified. Unlike send, public_send calls public methods only. When the method is identified by a string, the string is converted to a symbol.

Example

1.public_send(:puts, "hello")  # causes NoMethodError
