Method Summary

void addLogicalDependency(LogicalDependency node)


ActivationGroupNode getActivationGroupNode()


long getActivationNumber()
          Retrieve the activation number.

LinkedList getLogicalDependencies()


PropagationContext getPropagationContext()
          Retrieve the PropagationContext for the Activation

Rule getRule()
          Retrieve the Rule that was activated.

Tuple getTuple()
          Retrieve the Tuple that was activated.

boolean isActivated()


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

void setActivated(boolean activated)


void setActivationGroupNode(ActivationGroupNode activationGroupNode)
