Method Detail

getPositiveFactHandle

public InternalFactHandle getPositiveFactHandle()

setPositiveFactHandle

public void setPositiveFactHandle(InternalFactHandle positiveFactHandle)

public InternalFactHandle getNegativeFactHandle()

setNegativeFactHandle

public void setNegativeFactHandle(InternalFactHandle negativeFactHandle)

add

public void add(LinkedListNode node)

Description copied from class: LinkedList

Add a LinkedListNode to the list. If the LinkedList is empty then the first and last nodes are set to the added node.

Specified by:

add in interface BeliefSet

Overrides:

add in class LinkedList

Parameters:

node - The LinkedListNode to be added

remove

public void remove(LinkedListNode node)

Description copied from class: LinkedList

Removes a LinkedListNode from the list. This works by attach the previous reference to the child reference. When the node to be removed is the first node it calls removeFirst(). When the node to be removed is the last node it calls removeLast().

Specified by:

remove in interface BeliefSet

Overrides:

remove in class LinkedList

Parameters:

node - The LinkedListNode to be removed.

getBeliefSystem

public BeliefSystem getBeliefSystem()

Specified by:

getBeliefSystem in interface BeliefSet

getFactHandle

public InternalFactHandle getFactHandle()

Specified by:

getFactHandle in interface BeliefSet

isNegated

public boolean isNegated()

isConflicting

public boolean isConflicting()

isPositive

public boolean isPositive()

cancel

public void cancel(PropagationContext context)

Description copied from interface: BeliefSet

This will remove all entries and do clean up, like retract FHs.

Specified by:

cancel in interface BeliefSet

clear

public void clear(PropagationContext context)

Description copied from interface: BeliefSet

This will remove all entries, but not do cleanup, the FH is most likely needed else where

Specified by:

clear in interface BeliefSet

setWorkingMemoryAction

public void setWorkingMemoryAction(WorkingMemoryAction wmAction)

Specified by:

setWorkingMemoryAction in interface BeliefSet

getWorkingMemoryAction

public WorkingMemoryAction getWorkingMemoryAction()
