Author:: Mark Proctor, Bob McWhirter

AgendaGroup getAgendaGroup()


LinkedList getLogicalDependencies()


PropagationContext getPropagationContext()
          Retrieve the PropagationContext for the Activation

Rule getRule()

RuleFlowGroupNode getRuleFlowGroupNode()


GroupElement getSubRule()
          Retrieve the subrule that was activated.

Tuple getTuple()

boolean isActivated()


void remove()
          Cancel the Activation by removing it from the Agenda.

void setActivated(boolean activated)


void setActivationGroupNode(ActivationGroupNode activationGroupNode)


void setLogicalDependencies(LinkedList justified)


void setRuleFlowGroupNode(RuleFlowGroupNode ruleFlowGroupNode)
