Subject [jira] Commented: (JCR-1232) Merge UUID to NodeId
Date Fri, 23 Nov 2007 11:38:42 GMT

Thomas Mueller commented on JCR-1232:
-------------------------------------

> public UUID getUUID() { return new UUID(msb, lsb); } 

That would be a solution (however 'return this' would mean no overhead).

> change also jackrabbit-jcr-commons instead of just jackrabbit-core. 

The title suggest you want to merge the classes UUID and NodeId, and I fully agree that would
be great. But now I understand you want to copy & paste the source code? Sorry, I really
prefer having only one copy of the UUID code. It doesn't matter to me in what class that is,
but copying the source code is not an option for me; that would be -1.

> The current NodeId class is mostly just a wrapper around UUID, which causes two objects
to be instantiated for each node identifier that the system uses. The memory and processing
overhead is quite small, but given that there are tons of NodeId instances it would be good
to eliminate that overhead.
> There is also lots of code that just converts UUIDs to NodeIds and vice versa. We could
simplify such code if we just used NodeId everywhere.
> Also, we might want to open up the possibility of using non-UUID node identifiers at
some point in future, so it would make a lot of sense to remove the NodeId.getUUID method
and rely directly on NodeId and it's equals(), hashCode(), and toString() methods in many
places where we currently use UUIDs.
