 Consumer<Object> notifier)

Method Details

getSourceVariableDescriptor

public VariableDescriptor<Solution_> getSourceVariableDescriptor()

Specified by:

getSourceVariableDescriptor in interface SourcedVariableListener<Solution_,BasicVariableChangeEvent<Object>>

resetWorkingSolution

public void resetWorkingSolution(InnerScoreDirector<Solution_,?> scoreDirector)

Description copied from interface: InnerVariableListener

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 InnerVariableListener<Solution_,BasicVariableChangeEvent<Object>>

beforeChange

public void beforeChange(InnerScoreDirector<Solution_,?> scoreDirector,
 BasicVariableChangeEvent<Object> event)

Specified by:

beforeChange in interface InnerVariableListener<Solution_,BasicVariableChangeEvent<Object>>

afterChange

public void afterChange(InnerScoreDirector<Solution_,?> scoreDirector,
 BasicVariableChangeEvent<Object> event)

Specified by:

afterChange in interface InnerVariableListener<Solution_,BasicVariableChangeEvent<Object>>

close

public void close()

Description copied from interface: InnerVariableListener

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

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface InnerVariableListener<Solution_,BasicVariableChangeEvent<Object>>

insert

protected void insert(Object entity)

getAnchor

public @Nullable 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
