JENA-1559: PrefixMappingBase - algorithm and storage separation
> Avoid unnecessary prefix loading in GraphPrefixesProjection
> ------------------------------------------------------------
>
> Key: JENA-1559
> URL: https://issues.apache.org/jira/browse/JENA-1559
> Project: Apache Jena
> Issue Type: Task
> Affects Versions: Jena 3.7.0
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
> Priority: Major
>
> {{GraphPrefixesProjection}} loads all prefixes from the database (JENA-81).
> It was done that way because {{PrefixMappingImpl}} has internal
> datastructures that are not passing through lookup misses.
> Load as needed and rework the way the prefix implementation to cleanly
> separate algorithms from storage.
> Leave {{PrefixMappingImpl}} untouched - its name and details are too
> well-known.
