Constructor Detail

GenuineVariableDescriptor

public GenuineVariableDescriptor(EntityDescriptor<Solution_> entityDescriptor,
                                 MemberAccessor variableMemberAccessor)

Method Detail

processAnnotations

public void processAnnotations(DescriptorPolicy descriptorPolicy)

processPropertyAnnotations

protected abstract void processPropertyAnnotations(DescriptorPolicy descriptorPolicy)

processValueRangeRefs

protected void processValueRangeRefs(DescriptorPolicy descriptorPolicy,
                                     String[] valueRangeProviderRefs)

processStrength

protected void processStrength(Class<? extends Comparator> strengthComparatorClass,
                               Class<? extends SelectionSorterWeightFactory> strengthWeightFactoryClass)

linkVariableDescriptors

public void linkVariableDescriptors(DescriptorPolicy descriptorPolicy)

Specified by:

linkVariableDescriptors in class VariableDescriptor<Solution_>

isListVariable

public abstract boolean isListVariable()

isChained

public abstract boolean isChained()

isNullable

public abstract boolean isNullable()

acceptsValueType

public abstract boolean acceptsValueType(Class<?> valueType)

hasMovableChainedTrailingValueFilter

public boolean hasMovableChainedTrailingValueFilter()

getMovableChainedTrailingValueFilter

public SelectionFilter<Solution_,Object> getMovableChainedTrailingValueFilter()

getValueRangeDescriptor

public ValueRangeDescriptor<Solution_> getValueRangeDescriptor()

isValueRangeEntityIndependent

public boolean isValueRangeEntityIndependent()

isInitialized

public abstract boolean isInitialized(Object entity)

A nullable planning variable and PlanningListVariable are always considered initialized.

Parameters:

entity - never null

Returns:

true if the variable on that entity is initialized

isGenuineAndUninitialized

public boolean isGenuineAndUninitialized(Object entity)

Specified by:

isGenuineAndUninitialized in class VariableDescriptor<Solution_>

isReinitializable

public boolean isReinitializable(Object entity)

Decides whether an entity is eligible for initialization. This is not an opposite of isInitialized() because even a PlanningVariable.nullable() variable, which is always considered initialized, is reinitializable if its value is null.

getIncreasingStrengthSorter

public SelectionSorter<Solution_,Object> getIncreasingStrengthSorter()

getDecreasingStrengthSorter

public SelectionSorter<Solution_,Object> getDecreasingStrengthSorter()

getValueCount

public long getValueCount(Solution_ solution,
                          Object entity)

toString

public String toString()

Overrides:

toString in class Object
