[infinispan-issues] [JBoss JIRA] Commented: (ISPN-905) Enhance cache management methods on EmbeddedCacheManager

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12579601#comment-12579601 ] 

Galder Zamarreño commented on ISPN-905:
---------------------------------------

Patrick, could you please provide use cases for each of this operations so that we can understand better the meaning/aim of them?

For example, why do you need cacheExists()/getCacheIfExists()? I assume that it'd return true only if a cache with that name has been started. If stopped it'd returned false. Whether the cache is defined or not in the config would have no bearing here.

Wrt remove(), would not cache.stop() be enough for you? For example, stopping a cache removes all its contents. The only thing that cache.stop() could not do but CacheManager.remove() could, would be to update CacheManager's caches collection.

Your comment wrt remove() being transaction safe is also something that should prob affect cache.stop() as well. In fact, I think this should be separated into a diff jira.

FAO Manik, do you have any background information for this? For some reason it rings a bell that something related to this was discussed in dev/user forums but cannot find the link right now.
