[infinispan-issues] [JBoss JIRA] (ISPN-1792) API to return modification timestamp of a given entry

[Manik Surtani (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12662451#comment-12662451 ] 

Manik Surtani commented on ISPN-1792:
-------------------------------------

It's not that we need the timestamp to be negative for immortal entries, it is just that our internal structures are optimised and the InternalCacheEntry implementation used for immortal entries doesn't have a timestamp field.  Saves a long per entry.

If the application needs this, I suggest adding this as a part of your value object.

> To realise things like: programmatic delete last X entries from cache, I need the modification timestamp of the cache entry. ATM I store it inside the key object (cause I cannot modify value objects) and have my own index on this.
> Getting the modification timestamp using the advanced cache api would be really nice.
