Method Detail

getRuleOrigin

Rule getRuleOrigin()

getFactHandleOrigin

FactHandle getFactHandleOrigin()

getLeftTupleOrigin

LeftTuple getLeftTupleOrigin()

getOriginOffset

int getOriginOffset()

Returns the offset of the fact that initiated this propagation in the current propagation context. This attribute is mutable as the same fact might have different offsets in different rules or logical branches.

Returns:

-1 for not set, and from 0 to the tuple length-1.

setOriginOffset

void setOriginOffset(int offset)

Sets the origin offset to the given offset.

Parameters:

offset - -1 to unset or from 0 to tuple length-1

getActiveActivations

int getActiveActivations()

getDormantActivations

int getDormantActivations()

releaseResources

void releaseResources()

getEntryPoint

EntryPoint getEntryPoint()

setCurrentPropagatingOTN

void setCurrentPropagatingOTN(ObjectTypeNode otn)

When L&R unlinking is active, we need to keep track of the OTN that triggered this propagation.

isPropagating

boolean isPropagating(ObjectTypeNode otn)

shouldPropagateAll

boolean shouldPropagateAll()

setShouldPropagateAll

void setShouldPropagateAll(Object node)

getPropagationAttemptsMemory

ObjectHashSet getPropagationAttemptsMemory()

Keeps a list of nodes to which a propagation attempt fail because the node was unlinked.

addInsertAction

void addInsertAction(WorkingMemoryAction action)

removeInsertAction

void removeInsertAction(WorkingMemoryAction action)

getQueue2

LinkedList<WorkingMemoryAction> getQueue2()

evaluateActionQueue

void evaluateActionQueue(InternalWorkingMemory workingMemory)

getActiveWindowTupleList

WindowTupleList getActiveWindowTupleList()

setActiveWindowTupleList

void setActiveWindowTupleList(WindowTupleList list)

getModificationMask

long getModificationMask()

adaptModificationMaskForObjectType

                                                      InternalWorkingMemory workingMemory)

getObjectType

ObjectType getObjectType()

setObjectType

void setObjectType(ObjectType objectType)

getReaderContext
