Example 11 with IndexIterationPointer

use of com.hazelcast.internal.iteration.IndexIterationPointer in project hazelcast by hazelcast.

the class MapIndexScanP method splitOnMigration.

 * Method gets current partition table and proceeds with following procedure:

 * It splits the partitions assigned to the split according to the new
 * partition owner into disjoint sets, one for each owner.
 *
 * @param split the split to split
 * @return collection of new split units
