Class SimpleBeliefSystem

java.lang.Object
  org.drools.common.SimpleBeliefSystem

All Implemented Interfaces:

BeliefSystem

public class SimpleBeliefSystem
extends Object
implements BeliefSystem

Default implementation emulates classical Drools TMS behaviour.

Constructor Summary

SimpleBeliefSystem(InternalWorkingMemory wm, TruthMaintenanceSystem tms)

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.
void	insert(LogicalDependency node, BeliefSet beliefSet, PropagationContext context, ObjectTypeConf typeConf) TypeConf is already available, so we pass it, to avoid additional lookups
BeliefSet	newBeliefSet()
LogicalDependency	newLogicalDependency(Activation activation, InternalFactHandle handle, Object value)
void	read(LogicalDependency node, BeliefSet beliefSet, PropagationContext context, ObjectTypeConf typeConf)
