Examples with PartitioningStrategy com.hazelcast.core.PartitioningStrategy used on opensource projects

Example 6 with PartitioningStrategy

use of com.hazelcast.core.PartitioningStrategy in project hazelcast by hazelcast.

the class PartitioningStrategyFactoryTest method whenStrategyForMapAlreadyDefined_getPartitioningStrategy_returnsSameInstance.

// when a partitioning strategy has already been cached, then another invocation to obtain the partitioning
// strategy for the same map name retrieves the same instance
@Test
public void whenStrategyForMapAlreadyDefined_getPartitioningStrategy_returnsSameInstance() {
    PartitioningStrategyConfig cfg = new PartitioningStrategyConfig();
    cfg.setPartitioningStrategyClass("com.hazelcast.partition.strategy.StringPartitioningStrategy");
    // when we have already obtained the partitioning strategy for a given map name
    PartitioningStrategy partitioningStrategy = partitioningStrategyFactory.getPartitioningStrategy(mapName, cfg);
    // then once we get it again with the same arguments, we retrieve the same instance
    PartitioningStrategy cachedPartitioningStrategy = partitioningStrategyFactory.getPartitioningStrategy(mapName, cfg);
    assertSame(partitioningStrategy, cachedPartitioningStrategy);
}
