Subject [jira] [Commented] (DIRECTMEMORY-124) Create an utility class Iterable<V> over Cache<K,V>
Date Wed, 06 Feb 2013 16:01:14 GMT

    [ https://issues.apache.org/jira/browse/DIRECTMEMORY-124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13572526#comment-13572526

Jaromir Hamala commented on DIRECTMEMORY-124:
---------------------------------------------

I'm not sure if throwing an exception if the best idea - you can now iterate over the cache
only if you are sure there is no expired item. 
Otherwise you would need to catch RuntimeException.

> That'd be useful to iterate over cache values and at the same time avoid loading such
items into memory all together.
> E.g. I'm using DM to keep a huge list of graph vertices without spending too much memory,
but then I need at some point to iterate over them.
