get real class of a PageItem

Hi all,

There are two ways to get a pageItem :

-Document.allPageItems which is an array of extended objects of PageItem ( Rectangle, TextFrame, Oval.....) so we can have precisely the type of object we need.

-Document.pageItem.itemByID() which returns ONLY  objects as PageItem whatever their type.

I need to get a precise object(Rectangle, TextFrame).

But, to prevent looping through all PageItems, I am looking for a mixed method which returns a precise object on the same way of second method ( by usind id )

Thanks.
