An enum to configure the session query listener configuration.
Query results are collected by a listener class. The "STANDARD"
query listener class copies and disconnects fact handles and objects
for query results, making them somewhat resilient to some working
memory actions. But this copying is costly. For the cases where
no concurrency exists between query execution and other working memory
actions, a lightweight listener implementation can be used, preventing
the copy and improving query performance significantly.
