Interface KeyValueStore<K,V>

All Superinterfaces:

AutoCloseable, Closeable

All Known Subinterfaces:

JsonKeyValueStore<K,V>, KeyValueStoreWithVersion<K,O,V>, SerializedJavaKeyValueStore<K,V>, StringKeyValueStore

All Known Implementing Classes:

BinaryVersionedStore, InMemoryStringKeyValueStore, SimpleJavaSerializationStore, SimpleJsonKeyValueStore, SimpleKryoKeyValueStore, SimpleStringKeyValueStore, StringKeyValueStoreNoOp

public interface KeyValueStore<K,V>
extends Closeable

A map like interface that represents a key value store. This is not a map. KeyValueStore can be closed and flushed.

When you put(...) a value, it may return async so put does not return a value.

Method Detail

put

void put(K key,
       V value)

Put a key

Parameters:

key - key

value - value

putAll

void putAll(Map<K,V> values)

Put all values.

removeAll

void removeAll(Iterable<K> keys)

Remove all values

remove

void remove(K key)

Remove a single key.

search

KeyValueIterable<K,V> search(K startKey)

Search.

loadAll

KeyValueIterable<K,V> loadAll()

Load All Values. This is good for in-memory caches that have some keys that are persistent.

loadAllKeys

Collection<K> loadAllKeys()

Load All keys.

load

V load(K key)

loadAllByKeys

Map<K,V> loadAllByKeys(Collection<K> keys)

close

void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

isOpen

boolean isOpen()

isClosed

boolean isClosed()
