Return values
array<string|int, mixed> —The items array is a 3-dimensional array with the item_source as the first key and the share id as the second key to an array with the share info.
The key/value pairs included in the share info depend on the function originally called: If called by getItem(s)Shared: id, item_type, item, item_source, share_type, share_with, permissions, stime, file_source
If called by getItem(s)SharedWith: id, item_type, item, item_source, item_target, share_type, share_with, permissions, stime, file_source, file_target
This function allows the backend to control the output of shared items with custom formats. It is only called through calls to the public getItem(s)Shared(With) functions.
