LeftInputAdapterNode
public class LeftInputAdapterNode extends TupleSource implements ObjectSinkNode,NodeMemory(Code)
All asserting Facts must propagated into the right ObjectSink side of a BetaNode, if this is the first Pattern then there are no BetaNodes to propagate to. LeftInputAdapter is used to adapt an ObjectSink propagation into a TupleSource which propagates a ReteTuple suitable fot the right ReteTuple side of a BetaNode.

Constructor Summary
public  LeftInputAdapterNode(int id, ObjectSource source)
     Constructus a LeftInputAdapterNode with a unique id that receives FactHandle from a parent ObjectSource and adds it to a given pattern in the resulting Tuples.
Parameters:
  id - The unique id of this node in the current Rete network
Parameters:
  source - The parent node, where Facts are propagated from
Parameters:
  binder - An optional binder to filter out propagations.

Method Summary
public  voidassertObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)
     Takes the asserted FactHandleImpl received from the ObjectSource and puts it in a new ReteTuple before propagating to the TupleSinks
Parameters:
  handle - The asserted FactHandle/code>.
Parameters:
  context - The PropagationContext of the WorkingMemory action.

public  voidretractObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)
     Retract an existing FactHandleImpl by placing it in a new ReteTuple before proagating to the TupleSinks
Parameters:
  handle - The FactHandle/code> to retract.
Parameters:
  context - The PropagationContext of the WorkingMemory action.

Constructor Detail
LeftInputAdapterNode
public LeftInputAdapterNode(int id, ObjectSource source)(Code)
Constructus a LeftInputAdapterNode with a unique id that receives FactHandle from a parent ObjectSource and adds it to a given pattern in the resulting Tuples.
