FromEntityPropertyValueRangeDescriptor

public FromEntityPropertyValueRangeDescriptor(GenuineVariableDescriptor variableDescriptor,
                                              boolean addNullInValueRange,
                                              Method readMethod)

Method Detail

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.

Returns:

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

extractValueRange

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

Parameters:

solution - never null

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

Returns:

never null
