Method Detail

counterEnable

public DB.HTreeSetMaker counterEnable()

by default collection does not have counter, without counter updates are faster, but entire collection needs to be traversed to count items.

serializer

public DB.HTreeSetMaker serializer(Serializer<?> serializer)

keySerializer used to convert keys into/from binary form.

expireMaxSize

public DB.HTreeSetMaker expireMaxSize(long maxSize)

maximal number of entries in this map. Less used entries will be expired and removed to make collection smaller

expireStoreSize

public DB.HTreeSetMaker expireStoreSize(double maxStoreSize)

maximal size of store in GB, if store is larger entries will start expiring

expireAfterWrite

public DB.HTreeSetMaker expireAfterWrite(long interval,
                                         java.util.concurrent.TimeUnit timeUnit)
