Enum Constant Details

NONE

public static final CacheStrategy NONE

Creates a zero-capacity cache, where entries are always "absent". Cache.computeIfAbsent(Object, BiFunction) will always creates its value from the specified factory. Intended for use when some other mechanism already ensures mutually exclusive access to the requested state.

CONCURRENT

public static final CacheStrategy CONCURRENT

Creates a cache of entries in use by concurrent threads. Cache entries are auto-removed when the last requestor invokes Runnable.run() on the Runnable with which it was created.

Method Details

values

public static CacheStrategy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static CacheStrategy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:

IllegalArgumentException - if this enum class has no constant with the specified name
