Interface Storage<K,R>

Type Parameters:

K - the key type to be put in this storage.

R - the value type to be put in this storage.

All Known Implementing Classes:

StorageImpl

public interface Storage<K,R>

Represents actual storage layer behind a RecordStore. Includes basic storage operations.

Method Summary

Modifier and Type	Method and Description
void	clear(boolean isDuringShutdown)
boolean	containsKey(K key)

Method Detail

put

void put(K key,
         R record)

updateRecordValue

void updateRecordValue(K key,
                       R record,
                       Object value)

get

R get(K key)

getIfSameKey

R getIfSameKey(K key)

Gives the same result as get(Object), but with the additional constraint that the supplied key must not just be equal to, but be exactly the same key blob (at the same memory address) as the one stored. The implementation of this method is only needed for the HD memory-based implementations.

removeRecord

void removeRecord(R record)

containsKey

boolean containsKey(K key)

values

Collection<R> values()

size

int size()

isEmpty

boolean isEmpty()

clear

void clear(boolean isDuringShutdown)

destroy

void destroy(boolean isDuringShutdown)

getEntryCostEstimator

EntryCostEstimator getEntryCostEstimator()

setEntryCostEstimator

void setEntryCostEstimator(EntryCostEstimator entryCostEstimator)

disposeDeferredBlocks

void disposeDeferredBlocks()

getRandomSamples

Iterable<LazyEntryViewFromRecord> getRandomSamples(int sampleCount)

Used for sampling based eviction, returns sampled entries.

Parameters:

sampleCount - sample count.

Returns:

sampled entries.

fetchKeys

MapKeysWithCursor fetchKeys(int tableIndex,
                            int size)

fetchEntries

MapEntriesWithCursor fetchEntries(int tableIndex,
                                  int size,
                                  SerializationService serializationService)
