Enum SelectionCacheType

java.lang.Object

java.lang.Enum<SelectionCacheType>

org.optaplanner.core.config.heuristic.selector.common.SelectionCacheType

All Implemented Interfaces:

Serializable, Comparable<SelectionCacheType>

public enum SelectionCacheType
extends Enum<SelectionCacheType>

There is no INHERIT by design because 2 sequential caches provides no benefit, only memory overhead.

Enum Constant Detail

JUST_IN_TIME

public static final SelectionCacheType JUST_IN_TIME

Just in time, when the move is created. This is effectively no caching. This is the default for most selectors.

STEP

public static final SelectionCacheType STEP

When the step is started.

PHASE

public static final SelectionCacheType PHASE

When the phase is started.

SOLVER

public static final SelectionCacheType SOLVER

When the solver is started.

Method Detail

values

public static SelectionCacheType[] 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 (SelectionCacheType c : SelectionCacheType.values())
    System.out.println(c);

Returns:

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

valueOf

public static SelectionCacheType 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

resolve

public static SelectionCacheType resolve(SelectionCacheType cacheType,
                                         SelectionCacheType minimumCacheType)

isCached

public boolean isCached()

isNotCached

public boolean isNotCached()

max

public static SelectionCacheType max(SelectionCacheType a,
                                     SelectionCacheType b)
