Class RuleFlowGroupImpl

java.lang.Object
  org.drools.ruleflow.instance.impl.RuleFlowNodeInstance
      org.drools.ruleflow.instance.impl.RuleFlowSequenceNodeInstance

All Implemented Interfaces:

InternalRuleFlowGroup, IRuleFlowNodeInstance, RuleFlowGroup

public class RuleFlowGroupImpl
extends RuleFlowSequenceNodeInstance
implements InternalRuleFlowGroup

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.

Constructor Detail

RuleFlowGroupImpl

public RuleFlowGroupImpl(String name)

Construct a RuleFlowGroupImpl with the given name.

Parameters:

name - The RuleFlowGroup name.

Method Detail

getName

public String getName()

Specified by:

getName in interface RuleFlowGroup

---

setActive

public void setActive(boolean active)

Description copied from interface: InternalRuleFlowGroup

Activates or deactivates this RuleFlowGroup. When activating, all activations of this RuleFlowGroup are added to the agenda. As long as the RuleFlowGroup remains active, its activations are automatically added to the agenda. When deactivating, all activations of this RuleFlowGroup are removed to the agenda. As long as the RuleFlowGroup remains deactive, its activations are not added to the agenda.

Specified by:

setActive in interface InternalRuleFlowGroup

---

isActive

public boolean isActive()

Specified by:

isActive in interface InternalRuleFlowGroup

Specified by:

isActive in interface RuleFlowGroup

---

isAutoDeactivate

public boolean isAutoDeactivate()

Specified by:

isAutoDeactivate in interface RuleFlowGroup

---

setAutoDeactivate

public void setAutoDeactivate(boolean autoDeactivate)

Description copied from interface: RuleFlowGroup

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 RuleFlowGroup

---

clear

public void clear()

---

size

public int size()

Specified by:

size in interface RuleFlowGroup

---

addActivation

public void addActivation(Activation activation)

Specified by:

Specified by:

removeActivation in interface InternalRuleFlowGroup

---

isEmpty

Specified by:

isEmpty in interface RuleFlowGroup

---

iterator

public Iterator iterator()

Specified by:

iterator in interface RuleFlowGroup

---
