Method Detail

createSegmentMemory

public static SegmentMemory createSegmentMemory(LeftTupleSource tupleSource,
                                InternalWorkingMemory wm)

Initialises the NodeSegment memory for all nodes in the segment.

getQuerySegmentMemory

public static SegmentMemory getQuerySegmentMemory(InternalWorkingMemory wm,
                                  LeftTupleSource segmentRoot,
                                  QueryElementNode queryNode)

createChildSegments

public static void createChildSegments(InternalWorkingMemory wm,
                       SegmentMemory smem,
                       LeftTupleSinkPropagator sinkProp)

createChildSegment

public static SegmentMemory createChildSegment(InternalWorkingMemory wm,
                               LeftTupleNode node)

createChildSegmentForTerminalNode

public static SegmentMemory createChildSegmentForTerminalNode(LeftTupleNode node,
                                              Memory memory)

inSubNetwork

public static boolean inSubNetwork(RightInputAdapterNode riaNode,
                   LeftTupleSource leftTupleSource)

Is the LeftTupleSource a node in the sub network for the RightInputAdapterNode To be in the same network, it must be a node is after the two output of the parent and before the rianode.

isRootNode

public static boolean isRootNode(LeftTupleNode node,
                 org.kie.api.definition.rule.Rule removingRule)

Returns whether the node is the root of a segment. Lians are always the root of a segment. node cannot be null. The result should discount any removingRule. That means it gives you the result as if the rule had already been removed from the network.

Parameters:

node -

removingRule -

Returns:

isTipNode

public static boolean isTipNode(LeftTupleNode node,
                org.kie.api.definition.rule.Rule removingRule)

Returns whether the node is the tip of a segment. EndNodes (rtn and rian) are always the tip of a segment. node cannot be null. The result should discount any removingRule. That means it gives you the result as if the rule had already been removed from the network.

Parameters:

node -

removingRule -

Returns:

getQueryOtn

public static ObjectTypeNode getQueryOtn(LeftTupleSource lts)

getQueryLiaNode

public static LeftInputAdapterNode getQueryLiaNode(String queryName,
                                   ObjectTypeNode queryOtn)

isSet

public static boolean isSet(int mask,
            int bit)
