Interface Activation

All Superinterfaces:

org.drools.runtime.rule.Activation, Serializable

All Known Subinterfaces:

Queueable

All Known Implementing Classes:

AgendaItem, ScheduledAgendaItem

public interface Activation
extends Serializable, org.drools.runtime.rule.Activation

When a Tuple fully matches a rule it is added to the Agenda As an Activation. Each Activation is assigned a number, this number is determined by the WorkingMemory all Activations created from a single insert, update, retract are assgigned the same Activation number.

Method Detail

getRule

Rule getRule()

Specified by:

getRule in interface org.drools.runtime.rule.Activation

Returns:

The rule that was activated.

getSalience

int getSalience()

getSubRule

GroupElement getSubRule()

Retrieve the subrule that was activated.

Returns:

getActivationNumber

long getActivationNumber()

Each PropgationContext is assigned an id from a counter for the WorkingMemory action it represents. All Activations return this id as the ActivationNumber, thus all Activations created from the same PropgationContext will return the same long for this method.

Returns:

The activation number

getTuple

LeftTuple getTuple()

Retrieve the Tuple that was activated.

Returns:

The tuple.

getPropagationContext

PropagationContext getPropagationContext()

Retrieve the PropagationContext for the Activation

Specified by:

getPropagationContext in interface org.drools.runtime.rule.Activation

Returns:

The propagation context

remove

void remove()

Cancel the Activation by removing it from the Agenda.

setActivated

void setActivated(boolean activated)

isActivated

boolean isActivated()

getAgendaGroup

AgendaGroup getAgendaGroup()

getActivationGroupNode

ActivationGroupNode getActivationGroupNode()

setActivationGroupNode

void setActivationGroupNode(ActivationGroupNode activationGroupNode)
