Field Detail

key

public final BasicTSKey key

Key used to refer to this entry

rawEntry

public final com.fasterxml.storemate.store.Storable rawEntry

"Raw" serialized contents of the entry

creationTime

public final long creationTime

Timestamp of actual creation of entry; used for TTL calculations. Unlike insertion time (which may change), this will not be changed once entry has been added.

maxTTLSecs

public final int maxTTLSecs

Maximum time-to-live, in seconds, since creation. After this time is up, entry may be auto-expired, regardless of other settings.

This value may be sent by client; if not, a default value will be used.

Note that this setting has higher precedence that minTTLSinceAccessSecs, meaning that it will effectively limit maximum time an entry can live.

minTTLSinceAccessSecs

public final int minTTLSinceAccessSecs

Minimum time-to-live, in seconds, since the entry was last accessed.

This value may be sent by client; if not, a default value will be used.

Note that this value has lower precedence than maxTTLSecs, meaning that even if entry is regularly accessed, it can not "live forever".

lastAccessUpdateMethod

public final com.fasterxml.clustermate.service.LastAccessUpdateMethod lastAccessUpdateMethod
