Method Detail

getSourceVariableDescriptor

public VariableDescriptor getSourceVariableDescriptor()

Specified by:

getSourceVariableDescriptor in interface SourcedVariableListener<Object>

resetWorkingSolution in interface VariableListener<Object>

Parameters:

scoreDirector - never null

clearWorkingSolution

public void clearWorkingSolution(ScoreDirector scoreDirector)

Specified by:

clearWorkingSolution in interface StatefulVariableListener<Object>

Specified by:

afterEntityAdded in interface VariableListener<Object>

Specified by:

afterEntityAdded in interface VariableListener<Object>

Parameters:

scoreDirector - never null
