Subject [jira] [Commented] (DIRECTMEMORY-124) Create an utility class Iterable<V> over Cache<K,V>
Date Wed, 06 Feb 2013 14:25:13 GMT


Jaromir Hamala commented on DIRECTMEMORY-124:

Hi, iterator.hasNext() currently returns true even if the next object is expired. So the
returns null. Is this desired behaviour? 
Iterator probably could retrieve the object in the hasNext() method. And the next() method
should just return it. It the worst case we return an expired object (but which was not expired
during hasNext() call)

> 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.
