Example 1 with ListResult

use of com.redhat.service.bridge.infra.models.ListResult in project sandbox by 5733d9e2be6485d52ffa08870cabdee0.

the class ProcessorDAO method findByBridgeIdAndCustomerId.

public ListResult<Processor> findByBridgeIdAndCustomerId(String bridgeId, String customerId, QueryInfo queryInfo) {
    /*
         * Unfortunately we can't rely on Panaches in-built Paging due the fetched join in our query
         * for Processor e.g. join fetch p.bridge. Instead, we simply build a list of ids to fetch and then
         * execute the join fetch as normal. So the workflow here is:
         *
         * - Count the number of Processors on a bridge. If > 0
         * - Select the ids of the Processors that need to be retrieved based on the page/size requirements
         * - Select the Processors in the list of ids, performing the fetch join of the Bridge
         */
    Parameters p = Parameters.with(Bridge.CUSTOMER_ID_PARAM, customerId).and(Processor.BRIDGE_ID_PARAM, bridgeId);
    Long processorCount = countProcessorsOnBridge(p);
    if (processorCount == 0L) {
        return new ListResult<>(emptyList(), queryInfo.getPageNumber(), processorCount);
    }
    int firstResult = getFirstResult(queryInfo.getPageNumber(), queryInfo.getPageSize());
    TypedQuery<String> idsQuery = getEntityManager().createNamedQuery("PROCESSOR.idsByBridgeIdAndCustomerId", String.class);
