values
public static LocalCache.Strength[] 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 (LocalCache.Strength c : LocalCache.Strength.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static LocalCache.Strength 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 namejava.lang.NullPointerException
- if the argument is null
-
referenceValue
abstract <K,V> LocalCache.ValueReference<K,V> referenceValue(LocalCache.Segment<K,V> segment, LocalCache.ReferenceEntry<K,V> entry, V value, int weight)
Creates a reference for the given value according to this value strength.
-
defaultEquivalence
abstract Equivalence<java.lang.Object> defaultEquivalence()
Returns the default equivalence strategy used to compare and hash keys or values referenced at this strength. This strategy will be used unless the user explicitly specifies an alternate strategy.
