Method Detail

getRuleOrigin

Rule getRuleOrigin()

getTerminalNodeOrigin

TerminalNode getTerminalNodeOrigin()

getFactHandleOrigin

FactHandle getFactHandleOrigin()

setFactHandle

void setFactHandle(FactHandle factHandle)

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

releaseResources

void releaseResources()

getEntryPoint

EntryPointId getEntryPoint()

addInsertAction

void addInsertAction(WorkingMemoryAction action)

removeInsertAction

void removeInsertAction(WorkingMemoryAction action)

getQueue1

LinkedList<WorkingMemoryAction> getQueue1()

getQueue2

LinkedList<WorkingMemoryAction> getQueue2()

evaluateActionQueue

void evaluateActionQueue(InternalWorkingMemory workingMemory)

getModificationMask

                                                      InternalWorkingMemory workingMemory)

setModificationMask

void setModificationMask(long mask)

getObjectType

ObjectType getObjectType()

setObjectType

void setObjectType(ObjectType objectType)

getReaderContext
