  • Method Details

    • valueType

      Class<V> valueType()
      Retrieves the cache value type.
      Returns:

    • getNearCacheKeyAsync

      CompletableFuture<NearCacheKey<K,T>> getNearCacheKeyAsync(K key, boolean enforceKeyOnly)
      Serialize a key.
      Parameters:
      key - Key to serialize.
      enforceKeyOnly - Hints the underlying implementation that K must be key only.
      Returns:
      Serialized key.

    • getNearCacheKeysAsync

      CompletableFuture<Collection<NearCacheKey<K,T>>> getNearCacheKeysAsync(Iterable<? extends K> keys, boolean enforceKeyOnly)
      Serialize multiple keys.
      Parameters:
      keys - Keys to serialize.
      enforceKeyOnly - Hints the underlying implementation that K must be key only.
      Returns:
      Serialized keys.

    • getNearCacheValueAsync

      CompletableFuture<org.apache.ignite.internal.util.Pair<NearCacheKey<K,T>,NearCacheValue<V>>> getNearCacheValueAsync(@Nullable @Nullable org.apache.ignite.tx.Transaction tx, NearCacheKey<K,T> key)
      Get a value paired with a serialized key that was used to obtain it.
      Parameters:
      tx - Transaction.
      key - Key.
      Returns:
      A pair of serialized key that was used to get a value, and a nullable value itself.

    • getNearCacheValuesAsync

      CompletableFuture<Map<NearCacheKey<K,T>,NearCacheValue<V>>> getNearCacheValuesAsync(@Nullable @Nullable org.apache.ignite.tx.Transaction tx, Collection<NearCacheKey<K,T>> keys)
      Gets many values paired with a serialized key that was used to obtain it.
      Parameters:
      tx - Transaction.
      keys - Keys
      Returns:
      A collection of pairs of serialized key that was used to get a value, and a nullable value itself.
