Finding clash of JGoObjects

Hi all,
I’m painting JGoObjects (say JGoIconicNodes) in a view. I want to know whether the location I chose is free, i mean, is unoccupied by any other jgoobjects. Pls give a code sample for that and a lil bit of theory. The info I found in earlier postings were cryptic. Thats Y i’m reposting here. Thnx in advance

Did you find noccupied too cryptic? Could you be more precise about what you want to do?
