All Implemented Interfaces:

Serializable, Comparable<EventProcessingOption>, KnowledgeBaseOption, Option, SingleValueKnowledgeBaseOption

public enum EventProcessingOption
extends Enum<EventProcessingOption>
implements SingleValueKnowledgeBaseOption

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.

Method Detail

values

public static EventProcessingOption[] 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 (EventProcessingOption c : EventProcessingOption.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static EventProcessingOption valueOf(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.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getPropertyName

public String getPropertyName()

Returns the property name for this option

Specified by:

getPropertyName in interface Option

Returns:

getMode

public String getMode()

toString

public String toString()

Overrides:

toString in class Enum<EventProcessingOption>

toExternalForm

public String toExternalForm()

determineEventProcessingMode

public static EventProcessingOption determineEventProcessingMode(String mode)
