Interface ValueRangeDescriptor
- All Known Subinterfaces:
- EntityIndependentValueRangeDescriptor
- All Known Implementing Classes:
- AbstractFromPropertyValueRangeDescriptor, AbstractValueRangeDescriptor, CompositeValueRangeDescriptor, FromEntityPropertyValueRangeDescriptor, FromSolutionPropertyValueRangeDescriptor
public interface ValueRangeDescriptor
getVariableDescriptor
GenuineVariableDescriptor getVariableDescriptor()
- Returns:
- never null
isCountable
boolean isCountable()
- Returns:
- true if the
ValueRange
is countable
(for example a double value range between 1.2 and 1.4 is not countable)
isEntityIndependent
boolean isEntityIndependent()
- 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
mightContainEntity
boolean mightContainEntity()
- Returns:
- true if the
ValueRange
might contain a planning entity instance
(not necessarily of the same entity class as this entity class of this descriptor.
extractValueRange
ValueRange<?> extractValueRange(Solution solution,
Object entity)
- Parameters:
solution
- never nullentity
- never null. To avoid this parameter,
use EntityIndependentValueRangeDescriptor.extractValueRange(Solution)
instead.
- Returns:
- never null
