FromSolutionPropertyValueRangeDescriptor

public FromSolutionPropertyValueRangeDescriptor(GenuineVariableDescriptor<Solution_> variableDescriptor,
 boolean addNullInValueRange,
 MemberAccessor memberAccessor)

Method Details

isEntityIndependent

public boolean isEntityIndependent()

Description copied from interface: ValueRangeDescriptor

If this method return true, this instance is safe to cast to EntityIndependentValueRangeDescriptor, otherwise it requires an entity to determine the ValueRange.

Specified by:

isEntityIndependent in interface ValueRangeDescriptor<Solution_>

Returns:

true if the ValueRange is the same for all entities of the same solution

extractValueRange

public ValueRange<?> extractValueRange(Solution_ solution,
 Object entity)

Specified by:

extractValueRange in interface ValueRangeDescriptor<Solution_>

Parameters:

solution - never null

entity - never null. To avoid this parameter, use EntityIndependentValueRangeDescriptor.extractValueRange(Solution_) instead.

Returns:

never null

extractValueRange

public ValueRange<?> extractValueRange(Solution_ solution)

Description copied from interface: EntityIndependentValueRangeDescriptor

As specified by ValueRangeDescriptor.extractValueRange(Solution_, java.lang.Object).

Specified by:

extractValueRange in interface EntityIndependentValueRangeDescriptor<Solution_>

Parameters:

solution - never null

Returns:

never null
