Enum Constant Detail

LRU

public static final Eviction.Prioritizer LRU

Least Recently Used EvictionPrioritizer.

Ranks eviction candidates by their last access time. The entry which was last accessed the longest time ago is considered the most eligible for eviction.

LFU

public static final Eviction.Prioritizer LFU

Least Frequently Used EvictionPrioritizer.

Ranks eviction candidates by their frequency of use. The entry which has the lowest hit rate is considered the most eligible for eviction.

FIFO

public static final Eviction.Prioritizer FIFO

First In, First Out EvictionPrioritizer.

Ranks eviction candidates by their time of creation. The entry which was created the earliest is considered the most eligible for eviction.

Method Detail

values

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

Returns:

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

valueOf

public static Eviction.Prioritizer valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
