Constructor Detail

ExternalizedSingletonInverseVariableSupply

public ExternalizedSingletonInverseVariableSupply(VariableDescriptor<Solution_> sourceVariableDescriptor)

Method Detail

getSourceVariableDescriptor

public VariableDescriptor<Solution_> getSourceVariableDescriptor()

Specified by:

getSourceVariableDescriptor in interface SourcedVariableListener<Solution_,Object>

resetWorkingSolution

public void resetWorkingSolution(ScoreDirector<Solution_> scoreDirector)

Description copied from interface: VariableListener

Called when the entire working solution changes. In this event, the other before..()/after...() methods will not be called. At this point, implementations should clear state, if any.

Specified by:

resetWorkingSolution in interface VariableListener<Solution_,Object>

Parameters:

scoreDirector - never null

close

public void close()

Description copied from interface: VariableListener

Called before this VariableListener is thrown away and not used anymore.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface VariableListener<Solution_,Object>

beforeEntityAdded

public void beforeEntityAdded(ScoreDirector<Solution_> scoreDirector,
                              Object entity)

Specified by:

beforeEntityAdded in interface VariableListener<Solution_,Object>

Parameters:

scoreDirector - never null

entity - never null

afterEntityAdded

public void afterEntityAdded(ScoreDirector<Solution_> scoreDirector,
                             Object entity)

Specified by:

afterEntityAdded in interface VariableListener<Solution_,Object>

Parameters:

scoreDirector - never null

entity - never null

beforeVariableChanged

public void beforeVariableChanged(ScoreDirector<Solution_> scoreDirector,
                                  Object entity)

Specified by:

beforeVariableChanged in interface VariableListener<Solution_,Object>

Parameters:

scoreDirector - never null

entity - never null

afterVariableChanged

public void afterVariableChanged(ScoreDirector<Solution_> scoreDirector,
                                 Object entity)

Specified by:

afterVariableChanged in interface VariableListener<Solution_,Object>

Parameters:

scoreDirector - never null

entity - never null

beforeEntityRemoved

public void beforeEntityRemoved(ScoreDirector<Solution_> scoreDirector,
                                Object entity)

Specified by:

beforeEntityRemoved in interface VariableListener<Solution_,Object>

Parameters:

scoreDirector - never null

entity - never null

afterEntityRemoved

public void afterEntityRemoved(ScoreDirector<Solution_> scoreDirector,
                               Object entity)

Specified by:

afterEntityRemoved in interface VariableListener<Solution_,Object>

Parameters:

scoreDirector - never null

entity - never null

insert

protected void insert(Object entity)

retract

protected void retract(Object entity)

getInverseSingleton

public Object getInverseSingleton(Object value)

Description copied from interface: SingletonInverseVariableSupply
