Mengeluh, letak sahaja objek itu selepas memeriksa dan bertanya terus, anda memang malas

Anda tidak menyatakan pustaka yang anda gunakan Jika ada perpustakaan dan ada dokumentasi, lihat dokumentasi Jika tiada dokumentasi, lihat kod sumber Tiada konteks tentang cara objek anda dicipta

Mengenai soalan

Maklumat yang anda peroleh nampaknya berada dalam pembolehubah instance @info
