Enclosing interface:

CacheConfig

public static enum CacheConfig.EvictorAlgorithmType
extends Enum<CacheConfig.EvictorAlgorithmType>

Eviction algorithm type

• EvictorAlgorithmType.LRUEvictor is defined as an evictor type that uses a least recently used algorithm to decide which entries to evict when the cache entries map exceeds a maximum number of entries.
• EvictorAlgorithmType.LFUEvictor is defined as an evictor type that uses a least frequently used algorithm to decide which entries to evict when the cache entries map exceeds a maximum number of entries.

Method Details

values

public static CacheConfig.EvictorAlgorithmType[] 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 CacheConfig.EvictorAlgorithmType 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:

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
