[Owncloud] OCP_Share:: Usage guide need it .

[Arman Khalatyan]

Hi,
I am really iritated with this OCP_SHARE api , Can some one explain
how can I get simply the owner of the shared  source and the list of
users who got the share resource?
The OCP\Share::getItemSharedWithBySource(self::getItemType($source),
$source) returns  always null, but my source is listed in the oc_share
table.
I dont want to use database directly:)

Thanks,
Arman.
