[jboss-jira] [JBoss JIRA] Commented: (JBCACHE-707) PojoCache to aspectize JDom classes
[ http://jira.jboss.com/jira/browse/JBCACHE-707?page=comments#action_12339821 ]
Ben Wang commented on JBCACHE-707:
----------------------------------
I have looked into JDom internal classes:
1) JDom support of tree but not graph among the Element. That is, each Element has only
one parent.
2) Internal implementation relies heavily on ContentList and AttributeList, their own
implementation of List API. And they store the internal collection via Java array, e.g.,
Content[].
Challenges now is JBoss Aop can't do Java array interception. So we wouldn't know
the change to the array!
PojoCache to aspectize JDom classes
-----------------------------------
Key: JBCACHE-707
URL: http://jira.jboss.com/jira/browse/JBCACHE-707
Project: JBoss Cache
Issue Type: Task
Security Level: Public(Everyone can see)
Components: PojoCache
Reporter: Ben Wang
Assigned To: Ben Wang
Fix For: POJOCache
Original Estimate: 2 weeks
Remaining Estimate: 2 weeks
This is suggested by Bela during a customer visit. Idea is the customer is using JDom
internally to store the documents such as mail, fax, email, parcel, and the like. However,
for clustering purpose, each single update on document element would require replication
of the whole document. Not a very efficient process.
If PojoCache can aspectize JDom classes then fine-grained replication can be done
transparently.
