JTMSBeliefSetImpl

public JTMSBeliefSetImpl(BeliefSystem<M> beliefSystem,
                         InternalFactHandle rootHandle)

Method Detail

getPositiveFactHandle

public InternalFactHandle getPositiveFactHandle()

Specified by:

getPositiveFactHandle in interface JTMSBeliefSet<M extends JTMSMode<M>>

setPositiveFactHandle

public void setPositiveFactHandle(InternalFactHandle positiveFactHandle)

Specified by:

setPositiveFactHandle in interface JTMSBeliefSet<M extends JTMSMode<M>>

getNegativeFactHandle

public InternalFactHandle getNegativeFactHandle()

Specified by:

getNegativeFactHandle in interface JTMSBeliefSet<M extends JTMSMode<M>>

setNegativeFactHandle

public void setNegativeFactHandle(InternalFactHandle negativeFactHandle)

Specified by:

setNegativeFactHandle in interface JTMSBeliefSet<M extends JTMSMode<M>>

add

public void add(M 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<M extends JTMSMode<M>>

Overrides:

add in class LinkedList<M extends JTMSMode<M>>

Parameters:

node - The LinkedListNode to be added

remove

public void remove(M 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<M extends JTMSMode<M>>

Overrides:

remove in class LinkedList<M extends JTMSMode<M>>

Parameters:

node - The LinkedListNode to be removed.

getBeliefSystem

public BeliefSystem getBeliefSystem()

Specified by:

getBeliefSystem in interface BeliefSet<M extends JTMSMode<M>>

getFactHandle

public InternalFactHandle getFactHandle()

Specified by:

getFactHandle in interface BeliefSet<M extends JTMSMode<M>>

isNegated

public boolean isNegated()

Specified by:

isNegated in interface BeliefSet<M extends JTMSMode<M>>

isUndecided

public boolean isUndecided()

Specified by:

isUndecided in interface BeliefSet<M extends JTMSMode<M>>

isConflicting

public boolean isConflicting()

Specified by:

isConflicting in interface BeliefSet<M extends JTMSMode<M>>

isPositive

public boolean isPositive()

Specified by:

isPositive in interface BeliefSet<M extends JTMSMode<M>>

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<M extends JTMSMode<M>>

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<M extends JTMSMode<M>>

setWorkingMemoryAction

public void setWorkingMemoryAction(WorkingMemoryAction wmAction)

Specified by:

setWorkingMemoryAction in interface BeliefSet<M extends JTMSMode<M>>

getWorkingMemoryAction

public WorkingMemoryAction getWorkingMemoryAction()
