Project Proposal: Persistent Collections Framework
--------------------------------------------------
Key: COMMONSSITE-18
URL: https://issues.apache.org/jira/browse/COMMONSSITE-18
Project: Commons All
Issue Type: New Feature
Environment: Java 5.0 and higher, all platforms
Reporter: Matthias Rothe
The proposed Persistent Collections Framework aims at creating a collections
framework that seamlessly integrates with the JCF (Java Collections Framework)
while permitting transparent persistence.
Say you've got an ArrayList (or some other collection or map type) of data
objects you need to work with and store away. Usually you would have to load
the objects from some source (XML, database etc.) put them into the ArrayList
to manipulate or use them and later store any changes to them yourself.
I think this can be done more transparently by telling the ArrayList were to
get its objects, work on those objects and let the ArrayList handle all the
persistence issues. That would make working with persistent objects as simple
as working with in memory ones.
By using a strategy pattern any kind of data source could be wrapped and
therefore become accessible for any collection or map type.
