Class RuleFlowGroupImpl

java.lang.Object

org.drools.core.common.RuleFlowGroupImpl

All Implemented Interfaces:

InternalAgendaGroup, InternalRuleFlowGroup, org.kie.api.runtime.rule.AgendaGroup, org.kie.api.runtime.rule.RuleFlowGroup

public class RuleFlowGroupImpl
extends Object
implements InternalRuleFlowGroup, InternalAgendaGroup

Implementation of a RuleFlowGroup that collects activations of rules of this ruleflow-group. If this group is activated, all its activations are added to the agenda. As long as this group is active, its activations are added to the agenda. Deactivating the group removes all its activations from the agenda and collects them until it is activated again. By default, RuleFlowGroups are automatically deactivated when there are no more activations in the RuleFlowGroup. However, this can be configured.

public RuleFlowGroupImpl(String name,
                 boolean active,
                 boolean autoDeactivate)

Method Detail

getName

public String getName()

Specified by:

getName in interface org.kie.api.runtime.rule.AgendaGroup

Specified by:

getName in interface org.kie.api.runtime.rule.RuleFlowGroup

setWorkingMemory

public void setWorkingMemory(InternalWorkingMemory workingMemory)

Specified by:

setWorkingMemory in interface InternalAgendaGroup

getWorkingMemory

public InternalWorkingMemory getWorkingMemory()

Specified by:

getWorkingMemory in interface InternalAgendaGroup

hasRuleFlowListener

public void hasRuleFlowListener(boolean hasRuleFlowLister)

Specified by:

hasRuleFlowListener in interface InternalAgendaGroup

isRuleFlowListener

public boolean isRuleFlowListener()

Specified by:

isRuleFlowListener in interface InternalAgendaGroup

remove

public Activation remove()

Specified by:

remove in interface InternalAgendaGroup

peek

public Activation peek()

Specified by:

peek in interface InternalAgendaGroup

setActive

public void setActive(boolean active)

Specified by:

setActive in interface InternalAgendaGroup

isActive

public boolean isActive()

Returns:

boolean value indicating if the AgendaGroup is active and thus being evaluated.

setAutoFocusActivator

public void setAutoFocusActivator(PropagationContext ctx)

getAutoFocusActivator

public PropagationContext getAutoFocusActivator()

isAutoDeactivate

public boolean isAutoDeactivate()

Specified by:

isAutoDeactivate in interface InternalAgendaGroup

setAutoDeactivate

public void setAutoDeactivate(boolean autoDeactivate)

Description copied from interface: InternalAgendaGroup

Sets the auto-deactivate status of this RuleFlowGroup. If this is set to true, an active RuleFlowGroup automatically deactivates if it has no more activations. If it had no activations when it was activated, it will be deactivated immediately.

Specified by:

setAutoDeactivate in interface InternalAgendaGroup

clear
