public ExternalizedAnchorVariableSupply(VariableDescriptor<Solution_> previousVariableDescriptor,
 SingletonInverseVariableSupply nextVariableSupply)

Method Details

getSourceVariableDescriptor

public VariableDescriptor<Solution_> getSourceVariableDescriptor()

Specified by:

getSourceVariableDescriptor in interface SourcedVariableListener<Solution_>

resetWorkingSolution

public void resetWorkingSolution(@NonNull ScoreDirector<Solution_> scoreDirector)

Description copied from interface: AbstractVariableListener

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 AbstractVariableListener<Solution_,Object>

close

public void close()

Description copied from interface: AbstractVariableListener

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

Specified by:

close in interface AbstractVariableListener<Solution_,Object>

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

beforeEntityAdded

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

Specified by:

beforeEntityAdded in interface AbstractVariableListener<Solution_,Object>

afterEntityAdded

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

Specified by:

afterEntityAdded in interface AbstractVariableListener<Solution_,Object>

beforeVariableChanged

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

Specified by:

beforeVariableChanged in interface VariableListener<Solution_,Object>

afterVariableChanged

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

Specified by:

afterVariableChanged in interface VariableListener<Solution_,Object>

beforeEntityRemoved

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

Specified by:

beforeEntityRemoved in interface AbstractVariableListener<Solution_,Object>

afterEntityRemoved

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

Specified by:

afterEntityRemoved in interface AbstractVariableListener<Solution_,Object>

insert

protected void insert(Object entity)

getAnchor

public Object getAnchor(Object entity)

Specified by:

getAnchor in interface AnchorVariableSupply

Parameters:

entity - never null

Returns:

sometimes null, the anchor for the entity

toString

public String toString()

Overrides:

toString in class Object
