Proposal for a new List implementation: BackedList
--------------------------------------------------
Key: COLLECTIONS-270
URL: https://issues.apache.org/jira/browse/COLLECTIONS-270
Project: Commons Collections
Issue Type: New Feature
Components: List
Affects Versions: 3.2
Reporter: Sergio Bossa
Here is a new List implementation named BackedList, to use for transparently
accessing values of a generic data source as it were a normal List.
This List implementation dynamically accesses data source values through a
proper strategy object, keeping in memory only a limited, configurable, buffer
of values.
So, it is useful for:
1) Providing a List-like view of different data source values.
2) Avoiding to pre-load all values in a standard list, providing better
performances and less memory consumption.
As a side note, this list implementation is already used in production for
implementing pagination over a relational data source.
