[jbosscache-issues] [JBoss JIRA] Updated: (JBCACHE-1214) Can the cache be backed by LinkedHashSet instead of HashSet

Can the cache be backed by LinkedHashSet instead of HashSet ----------------------------------------------------------- Key: JBCACHE-1214 URL: https://jira.jboss.org/jira/browse/JBCACHE-1214 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Environment: RFC Reporter: Carl Shelbourne Assignee: Manik Surtani Priority: Optional Fix For: 3.2.0.GA Looking at the code it is noted that the cache is backed by a HashSet. Would it be possible to change this so that it is backed by a LinkedHashSet. There may or may not be performance benefits to this dependant on the usage. The primary reason for wanting it to be backed by a LinkedHashSet is the guaranteed ordering of the elements when iterated over. Having this guarantee would facilitate implementations of say a TableModel, but would make other iterations more predictable too.
