- Enclosing class:
- LruTaxonomyWriterCache
public static enum LruTaxonomyWriterCache.LRUType extends java.lang.Enum<LruTaxonomyWriterCache.LRUType>
Determines cache type. For guaranteed correctness - not relying on no-collisions in the hash function, LRU_STRING should be used.

values
public static LruTaxonomyWriterCache.LRUType[] 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 (LruTaxonomyWriterCache.LRUType c : LruTaxonomyWriterCache.LRUType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static LruTaxonomyWriterCache.LRUType valueOf(java.lang.String name)

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 namejava.lang.NullPointerException
