Method Detail

addRule

public static void addRule(TerminalNode tn,
                           InternalWorkingMemory[] wms)

removeRule

public static void removeRule(TerminalNode tn,
                              InternalWorkingMemory[] wms)

correctSegmentMemoryAfterSplitOnAdd

public static void correctSegmentMemoryAfterSplitOnAdd(SegmentMemory sm)

correctSegmentMemoryAfterSplitOnRemove

public static void correctSegmentMemoryAfterSplitOnRemove(SegmentMemory sm)

getSegmentPos

public static int getSegmentPos(LeftTupleSource lts,
                                Rule removingRule)

deleteFacts

public static void deleteFacts(LeftTupleSink startNode,
                               InternalWorkingMemory wm)

processLeftTuples

public static void processLeftTuples(LeftTupleSource node,
                                     LeftTupleSink peerNode,
                                     SegmentMemory smem,
                                     InternalWorkingMemory wm,
                                     boolean insert)

Populates the SegmentMemory with staged LeftTuples. If the parent is not a Beta or From node, it iterates up to find the first node with memory. If necessary It traverses to the LiaNode's ObjectTypeNode. It then iterates the LeftTuple chain, on a specific path to navigate down to where an existing LeftTuple is staged as delete. Or a new LeftTuple is created and staged as an insert.

Parameters:

node -

peerNode -

smem -

wm -

insert -

collectRtnPathMemories
