org.optaplanner.core.api.domain.lookup.LookUpStrategyType

All Implemented Interfaces:

Serializable, Comparable<LookUpStrategyType>

public enum LookUpStrategyType
extends Enum<LookUpStrategyType>

Determines how ScoreDirector.lookUpWorkingObject(Object) maps a problem fact or a planning entity from an external copy to the internal one.

Enum Constant Summary

Enum Constants

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.

Method Summary

Modifier and Type	Method	Description
static LookUpStrategyType	valueOf(String name)	Returns the enum constant of this type with the specified name.
static LookUpStrategyType[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

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 Detail

values

public static LookUpStrategyType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LookUpStrategyType c : LookUpStrategyType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LookUpStrategyType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
