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)
