Example 1 with IterationType

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

the class PublisherCreateOperation method runInitialQuery.

private QueryResult runInitialQuery() {
    QueryEngine queryEngine = getMapServiceContext().getQueryEngine(name);
    IterationType iterationType = info.isIncludeValue() ? IterationType.ENTRY : IterationType.KEY;
    Query query = Query.of().mapName(name).predicate(info.getPredicate()).iterationType(iterationType).build();
    return queryEngine.execute(query, Target.LOCAL_NODE);
}

Example 2 with IterationType

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

the class PagingPredicateHolder method asPredicate.

public <K, V> Predicate<K, V> asPredicate(SerializationService serializationService) {
    List<Map.Entry<Integer, Map.Entry<K, V>>> anchorList = anchorDataListHolder.asAnchorList(serializationService);
    Predicate predicate = serializationService.toObject(predicateData);
    Comparator comparator = serializationService.toObject(comparatorData);
    IterationType iterationType = IterationType.getById(iterationTypeId);
    PagingPredicateImpl<K, V> pagingPredicate = new PagingPredicateImpl<K, V>(anchorList, predicate, comparator, pageSize, page, iterationType);
    if (partitionKeyData == null) {
        return pagingPredicate;

    Query adjustedQuery = Query.of(query).iterationType(retrievalIterationType).build();
    if (adjustedQuery.getPredicate() instanceof PagingPredicateImpl) {
        ((PagingPredicateImpl) adjustedQuery.getPredicate()).setIterationType(query.getIterationType());
    } else {
