Method Detail

cgEvidenceIsPropagated

public boolean cgEvidenceIsPropagated()
                               throws ExceptionObjectNotAlive

Returns 'true' if CG evidence has been propagated in this JunctionTree; otherwise, returns 'false'.

Returns:

A boolean.

equilibriumIs

public boolean equilibriumIs(Domain.Equilibrium equilibrium)
                      throws ExceptionObjectNotAlive

Tests the Equilibrium type. Returns 'true' if the equilibrium of this JunctionTree can be obtained through a propagation using 'equilibrium' as the Equilibrium type; otherwise, returns 'false'.

Parameters:

equilibrium - the type of Equilibrium to test for.

Returns:

A boolean.

evidenceIsPropagated

public boolean evidenceIsPropagated()
                             throws ExceptionObjectNotAlive

Returns 'true' if evidence has been propagated in this JunctionTree; otherwise, returns 'false'.

Returns:

A boolean.

evidenceModeIs

public boolean evidenceModeIs(Domain.EvidenceMode mode)
                       throws ExceptionObjectNotAlive

Returns 'true' if the EvidenceMode matches 'mode'; otherwise, returns 'false'.

Parameters:

mode - the type of EvidenceMode to test for.

Returns:

A boolean.

evidenceToPropagate

public boolean evidenceToPropagate()
                            throws ExceptionObjectNotAlive

Returns 'true' if the JunctionTree contains evidence that has not been propagated; otherwise, returns 'false'.

Returns:

A boolean

getCliques

public CliqueList getCliques()
                      throws ExceptionObjectNotAlive

Returns the Cliques of this JunctionTree.

Returns:

A CliqueList

getConflict

public double getConflict()
                   throws ExceptionHugin,
                          ExceptionObjectNotAlive

Returns the conflict measure of the data inserted in this JunctionTree.

Returns:

A double.

getRoot

public Clique getRoot()
               throws ExceptionObjectNotAlive

Returns the root clique of this JunctionTree.

Returns:

A Clique.

likelihoodIsPropagated

public boolean likelihoodIsPropagated()
                               throws ExceptionObjectNotAlive

Returns 'true' if likelihoods have been propagated in this JunctionTree; otherwise, returns 'false'.

Returns:

A boolean.

propagate

public void propagate(Domain.Equilibrium equilibrium,
                      Domain.EvidenceMode evidenceMode)
               throws ExceptionObjectNotAlive

Propagates evidence in this JunctionTree.

Parameters:

equilibrium - the type of Equilibrium reached after the propagation.

evidenceMode - the EvidenceMode used.

tablesToPropagate

public boolean tablesToPropagate()
                          throws ExceptionObjectNotAlive

Returns 'true' if this JunctionTree contains updated tables that have not been propagated; otherwise, returns 'false'.

Returns:
