NO_LEVEL_SIZE

static final int NO_LEVEL_SIZE

Workaround for annotation limitation in bendableHardLevelsSize() and bendableSoftLevelsSize().

Element Detail

bendableHardLevelsSize

int bendableHardLevelsSize

Required for bendable scores.

For example with 3 hard levels, hard level 0 always outweighs hard level 1 which always outweighs hard level 2, which outweighs all the soft levels.

Returns:

0 or higher if the Score is a AbstractBendableScore, not used otherwise

Default:

-1

bendableSoftLevelsSize

int bendableSoftLevelsSize

Required for bendable scores.

For example with 3 soft levels, soft level 0 always outweighs soft level 1 which always outweighs soft level 2.

Returns:

0 or higher if the Score is a AbstractBendableScore, not used otherwise

Default:

-1

scoreDefinitionClass

Class<? extends ScoreDefinition> scoreDefinitionClass

Overrides the default determined ScoreDefinition to implement a custom one.

If this is not specified, the ScoreDefinition is automatically determined based on the return type of the annotated property (or field) on a PlanningSolution .

Returns:

PlanningScore.NullScoreDefinition when it is null (workaround for annotation limitation)

Default:

org.optaplanner.core.api.domain.solution.PlanningScore.NullScoreDefinition.class
