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 Details

    • 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 Details

    • values

      public static SelectionCacheType[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      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)
