Enum QueryListenerOption

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<QueryListenerOption>, Option, SingleValueOption, KieSessionOption, SingleValueKieSessionOption, SingleValueRuleRuntimeOption

    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.
    • Method Detail

      • 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())
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static QueryListenerOption valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        name - the name of the enum constant to be returned.
        the enum constant with the specified name
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
