Returns:

the tupleSource

setTupleSource

public void setTupleSource(LeftTupleSource tupleSource)

Parameters:

tupleSource - the tupleSource to set

getKnowledgeBase

public InternalKnowledgeBase getKnowledgeBase()

Returns context rulebase

setObjectTypeNodeMemoryEnabled

public void setObjectTypeNodeMemoryEnabled(boolean hasObjectTypeMemory)

isQuery

public boolean isQuery()

getCurrentEntryPoint

public EntryPointId getCurrentEntryPoint()

Returns:

the currentEntryPoint

setCurrentEntryPoint

public void setCurrentEntryPoint(EntryPointId currentEntryPoint)

Parameters:

currentEntryPoint - the currentEntryPoint to set

getNodes
