> Key: COLLECTIONS-248
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-248
> Project: Commons Collections
> Issue Type: New Feature
> Components: Collection
> Reporter: Nicolas Marchildon
> Fix For: 4.x
>
> Attachments: CollectionLoader.java, TrackingCollection.java,
> TrackingCollectionTest.java
>
>
> Sometimes you need to keep track of what was added and what was removed
> from a collection, and that is what we created TrackingCollection for.
> Additionally, since we were implementing lazy-loading of collections of
> persistent objects, we introduced a CollectionLoader that is used by the
> TrackingCollection when it has to access all of its elements. It is
> still possible however to use the TrackingCollection without a loader,
> and it will simply start empty and be considered loaded.
