GetUpdateID
The GetUpdateID method returns the update ID that uniquely identifies the current generation or version of this link-source object's content.
ODUpdateID GetUpdateID ();
return value
The update ID of this link-source object's content.

DISCUSSION
If your part is the source part for this link-source object, you can call this method to determine the current version of this link-source object's content.
You can compare the returned update ID with a previously saved ID to establish whether the content needs to be updated. There is no implicit ordering of update ID values; they offer tests for equality only, with no indication of the time or nature of any link changes.
