Some code I use to iterate through CMIS query results.

CmisQueryAll.java

import java.util.ArrayList;
import java.util.List;
import org.apache.chemistry.opencmis.client.api.ItemIterable;
import org.apache.chemistry.opencmis.client.api.OperationContext;
import org.apache.chemistry.opencmis.client.api.QueryResult;
import org.apache.chemistry.opencmis.client.api.Session;

/**
 * See the CMIS query API for an understanding of items per page and all versions.
 */
public static List<QueryResult> queryAll(Session session, String query, int itemsPerPage, boolean allVersions) {
    OperationContext context = session.createOperationContext();
    context.setMaxItemsPerPage(itemsPerPage);
    ItemIterable<QueryResult> results = session.query(query, allVersions, context);

    List<QueryResult> allResults = new ArrayList<>();
    for (long i = 0;; ++i) {
        ItemIterable<QueryResult> pageResults = results.skipTo(itemsPerPage * i).getPage();
        for (QueryResult result : pageResults) {
            allResults.add(result);
        }
        /*
         * The getHasMoreItems method call _should_ be sufficient; however, I have observed in Chemistry 0.7.0
         * instances of "infinite looping" in certain circumstances, and adding this additional check that
         * the number of page items is less than 1 seems will prevent this from happening.
         */
        if (!pageResults.getHasMoreItems() || pageResults.getPageNumItems() < 1) {
            break;
        }
    }
    return allResults;
}
