Cad é an @ in RGSS scripteanna?

Cur síos ar @ Comhréir na scripteanna san RGSS

Sainmhíníonn sé athróg shamplach do rang. Chun a bheith in ann athróga den chineál seo a léamh agus a scríobh ní mór duit modhanna rochtana a chruthú dóibh freisin. Is féidir leat an shortcode attr_reader, attr_writer, nó attr_accessor a úsáid freisin chun na hoibreoirí ábhartha a luchtú go huathoibríoch.
