----------------------------------
Summary: QueryEngine.executeQuery needs a session parameter
Key: OAK-241
URL: https://issues.apache.org/jira/browse/OAK-241
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Thomas Mueller
Assignee: Thomas Mueller
Priority: Minor
The method QueryEngine.executeQuery currently needs a ContentSession parameter,
even thought the instance was retrieved from the ContentSession using
ContentSession.getQueryEngine(). This is a bit confusing.
To solve this, we could rename the QueryEngine interface to SessionQueryEngine,
change QueryEngineImpl so it no longer implements any interface, add a class
SessionQueryEngineImpl that calls the QueryEngineImpl methods (1:1, except for
executeQuery where it adds the session parameter).
An alternative would be to change the existing QueryEngineImpl so a new
instance is created for each session. But I prefer not todo this as
conceptually there is only one query engine.
