Summary: Avoid unnecessary preix 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
{{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.
