Enum CacheConfig.EvictorAlgorithmType
- java.lang.Object
java.lang.Enum<CacheConfig.EvictorAlgorithmType>
com.ibm.wsspi.cache.CacheConfig.EvictorAlgorithmType
All implemented interfaces:
java.io.Serializable, java.lang.Comparable<CacheConfig.EvictorAlgorithmType>
Enclosing interface:
- public static enum CacheConfig.EvictorAlgorithmType
- extends java.lang.Enum<CacheConfig.EvictorAlgorithmType>
- 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.

Enum Constant Detail
LRUEvictor
- public static final CacheConfig.EvictorAlgorithmType LRUEvictor
An Evictor that uses the Least Recently Used Algorithm
LFUEvictor
- public static final CacheConfig.EvictorAlgorithmType LFUEvictor
An Evictor that uses the Least Frequently Used Algorithm
Method Detail
values
- public static CacheConfig.EvictorAlgorithmType[] 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 (CacheConfig.EvictorAlgorithmType c : CacheConfig.EvictorAlgorithmType.values()) System.out.println(c);
Returns:
an array containing the constants of this enum type, in
the order they are declared
valueOf
- public static CacheConfig.EvictorAlgorithmType 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
