| 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. |
| 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.
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. This binder will exist whena predicate is used in the first pattern, for instance |
| assertObject | | public void assertObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)(Code) | | 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.
Parameters:
workingMemory - the WorkingMemory session. |
| attach | | public void attach()(Code) | | |
| getNextObjectSinkNode | | public ObjectSinkNode getNextObjectSinkNode()(Code) | | Returns the next node
The next ObjectSinkNode |
| getPreviousObjectSinkNode | | public ObjectSinkNode getPreviousObjectSinkNode()(Code) | | Returns the previous node
The previous ObjectSinkNode |
| hashCode | | public int hashCode()(Code) | | |
| retractObject | | public void retractObject(InternalFactHandle handle, PropagationContext context, InternalWorkingMemory workingMemory)(Code) | | 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.
Parameters:
workingMemory - the WorkingMemory session. |
| setNextObjectSinkNode | | public void setNextObjectSinkNode(ObjectSinkNode next)(Code) | | Sets the next node
Parameters:
next - The next ObjectSinkNode |

Parameters:
previous - The previous ObjectSinkNode |
