Class HazelcastSortAccessor

java.lang.Object

org.springframework.data.hazelcast.repository.query.HazelcastSortAccessor

All Implemented Interfaces:

org.springframework.data.keyvalue.core.SortAccessor<Comparator<Map.Entry<?,?>>>

public class HazelcastSortAccessor
extends Object
implements org.springframework.data.keyvalue.core.SortAccessor<Comparator<Map.Entry<?,?>>>

Implements sorting for Hazelcast repository queries.

Although SpelPropertyComparator would do most of the work, this is not serializable so cannot work in a cluster. Also, do not wish to assume anything other than Hazelcast classes are available on remote nodes.
