android - Remove an object class in Corona -

i have new problem... have constuctor this:

function box.new(indexbox, item, imgclose, imgopen) -- constructor   local object = {     indexbox = indexbox,     item = item,     imgclose = display.newimage( imgclose ),     imgopen = imgopen   }   return setmetatable( object, box_mt ) end 

during process i've created box objects , i've finished use them, want remove box objects removing content of object, included image. there easy way this?

thanks!

to delete all box objects, need way access of them. traditional , far (imho) approach have table storing references box 'instances'. such approach need is:

--boxestable contains boxes declared _,box in ipairs(boxestable)     box:removeself() end
