ValueSelectorFactory

public ValueSelectorFactory(ValueSelectorConfig valueSelectorConfig)

Method Detail

create

public static <Solution_> ValueSelectorFactory<Solution_> create(ValueSelectorConfig valueSelectorConfig)

extractVariableDescriptor

public GenuineVariableDescriptor<Solution_> extractVariableDescriptor(HeuristicConfigPolicy<Solution_> configPolicy,
                                                                      EntityDescriptor<Solution_> entityDescriptor)

buildValueSelector

public ValueSelector<Solution_> buildValueSelector(HeuristicConfigPolicy<Solution_> configPolicy,
                                                   EntityDescriptor<Solution_> entityDescriptor,
                                                   SelectionCacheType minimumCacheType,
                                                   SelectionOrder inheritedSelectionOrder)

Parameters:

configPolicy - never null

entityDescriptor - never null

minimumCacheType - never null, If caching is used (different from SelectionCacheType.JUST_IN_TIME), then it should be at least this SelectionCacheType because an ancestor already uses such caching and less would be pointless.

inheritedSelectionOrder - never null

Returns:

never null
