Method Detail

getPropagationNumber

long getPropagationNumber()

getType

PropagationContext.Type getType()

getRuleOrigin

RuleImpl getRuleOrigin()

getTerminalNodeOrigin

TerminalNode getTerminalNodeOrigin()

getFactHandle

InternalFactHandle getFactHandle()

Returns:

fact handle that was inserted, updated or retracted that created the PropagationContext

setFactHandle

void setFactHandle(InternalFactHandle factHandle)

getLeftTupleOrigin

Tuple 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

getQueue2

LinkedList<WorkingMemoryAction> getQueue2()

                                                      InternalWorkingMemory workingMemory)

setModificationMask

void setModificationMask(BitMask mask)

getReaderContext
