> Support for Transformer in LazyList
> -----------------------------------
>
> Key: COLLECTIONS-694
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-694
> Project: Commons Collections
> Issue Type: Improvement
> Components: List
> Affects Versions: 4.2
> Reporter: Stephan Windmüller
> Priority: Minor
>
> {{LazyList}} supports a {{Factory}} for creating new elements on first
> access. Since a {{Factory}} does not take any arguments, those elements can
> not depend on any input values.
> A possible use case is a list of objects from a database, fetched by their
> id. If an element at a specific position is requested, it is retrieved from
> the database lazily. This would require support of a {{Transformer}} (from id
> to database object).
