### Public Instance Methods

to_proc() click to toggle source

Returns a `Proc` object that takes arguments and yields them.

This method is implemented so that a `Yielder` object can be directly passed to another method as a block argument.

    enum = Enumerator.new { |y|
      Dir.glob("*.rb") { |file|
        File.open(file) { |f| f.each_line(&y) }
      }
    }

    static VALUE
    yielder_to_proc(VALUE obj)
    {
        VALUE method = rb_obj_method(obj, sym_yield);

        return rb_funcall(method, idTo_proc, 0);
    }
