Class MapPartitionIterator<K,V>

java.lang.Object

com.hazelcast.map.impl.iterator.AbstractMapPartitionIterator<K,V>

com.hazelcast.map.impl.iterator.MapPartitionIterator<K,V>

All Implemented Interfaces:

Iterator<Map.Entry<K,V>>

public class MapPartitionIterator<K,V>
extends AbstractMapPartitionIterator<K,V>

Iterator for iterating map entries in the partitionId. The values are not fetched one-by-one but rather in batches. NOTE Iterating the map should be done only when the IMap is not being mutated and the cluster is stable (there are no migrations or membership changes). In other cases, the iterator may not return some entries or may return an entry twice.
