Examples with MutableLong com.hazelcast.internal.util.MutableLong used on opensource projects

Example 1 with MutableLong

use of com.hazelcast.internal.util.MutableLong in project hazelcast by hazelcast.

the class MapProxySupport method putAllInternal.

/**
 * This method will group all entries per partition and send one operation
 * per member. If there are e.g. five keys for a single member, even if
 * they are from different partitions, there will only be a single remote
 * invocation instead of five.
 * <p>
 * There is also an optional support for batching to send smaller packages.
 * Takes care about {@code null} checks for keys and values.
 *
 * @param future iff not-null, execute asynchronously by completing this future.
 *               Batching is not supported in async mode
