public enum QueryListenerOption extends java.lang.Enum<QueryListenerOption> implements SingleValueRuleRuntimeOption
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.

values
public static QueryListenerOption[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (QueryListenerOption c : QueryListenerOption.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
