[jQuery] How to retrieve jQuery.query?


Say a user called $('div.foo') I would like to get this 'div.foo' from
within my plug-in context.
I look through the code and couldn't find a property which contain
this data;
I was thinking that 'query' is the appropriate name for this property
example usage:
$.fn.MyPlugIn = function (){
if (/table|thead|tbody|th|tr|td/.test($.query){
// do the table thing
}
else {
// do the chair thing ;-)
}
}
$('table').MyPlugIn();
$('div').MyPlugIn
