Enum Class EventProcessingOption

java.lang.Enum<EventProcessingOption>

org.kie.api.conf.EventProcessingOption

All Implemented Interfaces:

Serializable, Comparable<EventProcessingOption>, Constable, KieBaseOption, Option, SingleValueKieBaseOption, SingleValueOption, SingleValueRuleBaseOption

public enum EventProcessingOption
extends Enum<EventProcessingOption>
implements SingleValueRuleBaseOption

An Enum for Event Processing option. drools.eventProcessingMode = <identity|equality> When the rulebase is compiled in the CLOUD (default) event processing mode, it behaves just like a regular rulebase. When the rulebase is compiled in the STREAM event processing mode, additional assumptions are made. These assumptions allow the engine to perform a few optimisations like:

• reasoning over absence of events (NOT CE), automatically adds an appropriate duration attribute to the rule in order to avoid early rule firing.
• memory management techniques may be employed when an event no longer can match other events due to session clock continuous increment.
