Enum Constant	Description
EQUALITY	Map by equals(Object) and hashCode().
NONE	There is no mapping and ScoreDirector.lookUpWorkingObject(Object) must not be used.
PLANNING_ID_OR_FAIL_FAST	Map by the same PlanningId field or method.
PLANNING_ID_OR_NONE	Map by the same PlanningId field or method.

Enum Constant Details

PLANNING_ID_OR_NONE

public static final LookUpStrategyType PLANNING_ID_OR_NONE

Map by the same PlanningId field or method. If there is no such field or method, there is no mapping and ScoreDirector.lookUpWorkingObject(Object) must not be used. If there is such a field or method, but it returns null, it fails fast.

This is the default.

PLANNING_ID_OR_FAIL_FAST

public static final LookUpStrategyType PLANNING_ID_OR_FAIL_FAST

Map by the same PlanningId field or method. If there is no such field or method, it fails fast.

EQUALITY

public static final LookUpStrategyType EQUALITY

Map by equals(Object) and hashCode(). If any of these two methods is not overridden by the working object's class or some of its superclasses, ScoreDirector.lookUpWorkingObject(Object) must not be used because it cannot work correctly with Object's equals and hashCode implementations.

NONE

public static final LookUpStrategyType NONE

There is no mapping and ScoreDirector.lookUpWorkingObject(Object) must not be used.

Method Details

values

public static LookUpStrategyType[] values()
