Refactor the current Collection classes (list and set) ------------------------------------------------------ Key: JBCACHE-485 URL: http://jira.jboss.com/jira/browse/JBCACHE-485 Project: JBoss Cache Issue Type: Task Security Level: Public(Everyone can see) Components: PojoCache Reporter: Ben Wang Assigned To: Ben Wang Priority: Critical Fix For: PojoCache Attachments: set.diff Original Estimate: 4 weeks Remaining Estimate: 4 weeks Current implementation of Collection uses direct coupling to the cache store indices. E.g., we map them into subtree according to index ordering. This is not very desirable for performance reason. We should consider to provide a indirect mapping such that it is considered a graph instead of ordered tree. Or we should investigate whether it is possible to use a proxy operates on java.util.* classes such that we don't need to have our own implementation. The JDK lincense aside, ArrayList, e.g., uses an internal transient array. Is it possible to "aspectize" on that array only?
