The Rete class is the root Object. All objects are asserted into the Rete node where it propagates to all matching ObjectTypeNodes. The first time an instance of a Class type is asserted it does a full iteration of all ObjectTyppeNodes looking for matches, any matches are then cached in a HashMap which is used for future assertions. While Rete extends ObjectSource nad implements ObjectSink it nulls the methods attach(), remove() and updateNewNode() as this is the root node they are no applicable See Also:   ObjectTypeNode author:    Mark Proctor author:    Bob McWhirter Inner Class :public static interface ObjectTypeConf Inner Class :public static class FactTemplateTypeConf implements ObjectTypeConf,Serializable Inner Class :public static class ClassObjectTypeConf implements ObjectTypeConf,Serializable Constructor Summary public   Rete(InternalRuleBase ruleBase)      Method Summary protected  void addObjectSink(ObjectSink objectSink)      Adds the TupleSink so that it may receive Tuples propagated from this TupleSource. public  void assertObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)      This is the entry point into the network for all asserted Facts. public  void attach()      public  void attach(InternalWorkingMemory[] workingMemories)      public  Object createMemory(RuleBaseConfiguration config)      public  boolean equals(Object object)      public  ObjectHashMap getObjectTypeNodes()      public  InternalRuleBase getRuleBase()      public  int hashCode()      public  void remove(BaseNode node, InternalWorkingMemory[] workingMemories)      protected  void removeObjectSink(ObjectSink objectSink)      public  void retractObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)      Retract a fact object from this RuleBase and the specified WorkingMemory. public  void updateSink(ObjectSink sink, PropagationContext context, InternalWorkingMemory workingMemory)      Constructor Detail Rete public Rete(InternalRuleBase ruleBase)(Code) Method Detail addObjectSink protected void addObjectSink(ObjectSink objectSink)(Code) Adds the TupleSink so that it may receive Tuples propagated from this TupleSource. Parameters:   tupleSink - The TupleSink to receive propagatedTuples. assertObject public void assertObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)(Code) This is the entry point into the network for all asserted Facts. Iterates a cache of matching ObjectTypdeNodes asserting the Fact. If the cache does not exist it first iteraes and builds the cache. Parameters:   handle - The FactHandle of the fact to assert Parameters:   context - The PropagationContext of the WorkingMemory action Parameters:   workingMemory - The working memory session. attach public void attach()(Code) attach public void attach(InternalWorkingMemory[] workingMemories)(Code) createMemory public Object createMemory(RuleBaseConfiguration config)(Code) equals public boolean equals(Object object)(Code) getObjectTypeNodes public ObjectHashMap getObjectTypeNodes()(Code) getRuleBase public InternalRuleBase getRuleBase()(Code) hashCode public int hashCode()(Code) remove public void remove(BaseNode node, InternalWorkingMemory[] workingMemories)(Code) removeObjectSink protected void removeObjectSink(ObjectSink objectSink)(Code) retractObject public void retractObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)(Code) Retract a fact object from this RuleBase and the specified WorkingMemory. Parameters:   handle - The handle of the fact to retract.
