isRecordingStats
public boolean isRecordingStats()Description copied from interface:Policy
Returns whether the cache statistics are being accumulated.- Specified by:
isRecordingStats
in interfacePolicy<K,
V> - Returns:
- if cache statistics are being recorded
-
eviction
Description copied from interface:Policy
Returns access to perform operations based on the maximum size or maximum weight eviction policy. If the cache was not constructed with a size-based bound or the implementation does not support these operations, an emptyOptional
is returned. -
expireAfterAccess
Description copied from interface:Policy
Returns access to perform operations based on the time-to-idle expiration policy. This policy determines that an entry should be automatically removed from the cache once a fixed duration has elapsed after the entry's creation, the most recent replacement of its value, or its last access. Access time is reset by all cache read and write operations (includingCache.asMap().get(Object)
andCache.asMap().put(K, V)
), but not by operations on the collection-views ofCache.asMap()
.If the cache was not constructed with access-based expiration or the implementation does not support these operations, an empty
Optional
is returned.- Specified by:
expireAfterAccess
in interfacePolicy<K,
V> - Returns:
- access to low-level operations for this cache if a time-to-idle expiration policy is used
-
expireAfterWrite
Description copied from interface:Policy
Returns access to perform operations based on the time-to-live expiration policy. This policy determines that an entry should be automatically removed from the cache once a fixed duration has elapsed after the entry's creation, or the most recent replacement of its value.If the cache was not constructed with write-based expiration or the implementation does not support these operations, an empty
Optional
is returned.- Specified by:
expireAfterWrite
in interfacePolicy<K,
V> - Returns:
- access to low-level operations for this cache if a time-to-live expiration policy is used
-
refreshAfterWrite
Description copied from interface:Policy
Returns access to perform operations based on the time-to-live refresh policy. This policy determines that an entry should be automatically reloaded once a fixed duration has elapsed after the entry's creation, or the most recent replacement of its value.If the cache was not constructed with write-based refresh or the implementation does not support these operations, an empty
Optional
is returned.- Specified by:
refreshAfterWrite
in interfacePolicy<K,
V> - Returns:
- access to low-level operations for this cache if a time-to-live refresh policy is used
