Method Summary

void	delete(LogicalDependency node, BeliefSet beliefSet, PropagationContext context) The typeConf has not yet been looked up, so we leave it to the implementation to decide if it needs it or not.
TruthMaintenanceSystem	getTruthMaintenanceSystem()
void	insert(LogicalDependency node, BeliefSet beliefSet, PropagationContext context, ObjectTypeConf typeConf) TypeConf is already available, so we pass it, to avoid additional lookups
protected void	insertBelief(LogicalDependency node, ObjectTypeConf typeConf, JTMSBeliefSet jtmsBeliefSet, PropagationContext context, boolean wasEmpty, boolean wasNegated, boolean isUndecided)
BeliefSet	newBeliefSet(InternalFactHandle fh)
LogicalDependency	newLogicalDependency(Activation activation, BeliefSet beliefSet, Object object, Object value)
