Example 1 with Predicate

use of org.jboss.pnc.spi.datastore.repositories.api.Predicate in project pnc by project-ncl.

the class BuildProviderImpl method getBuilds.

/**
 * Returns the page of builds (running or finished) filtered by given BuildPageInfo and predicate.
 */

    int firstPossibleDBIndex = pageInfo.getPageIndex() * pageInfo.getPageSize() - runningBuilds.size();
    int lastPossibleDBIndex = (pageInfo.getPageIndex() + 1) * pageInfo.getPageSize() - 1;
    int toSkip = min(runningBuilds.size(), pageInfo.getPageIndex() * pageInfo.getPageSize());
    Predicate<BuildRecord>[] predicates = preparePredicates(dbPredicate, pageInfo.getQ(), pageInfo.getBuildConfigName());
    Comparator<Build> comparing = Comparator.comparing(Build::getSubmitTime).reversed();
    if (!StringUtils.isEmpty(pageInfo.getSort())) {
        comparing = rsqlPredicateProducer.getComparator(pageInfo.getSort());

    int hits = repository.count(predicates) + runningBuilds.size();
    return new Page<>(pageInfo.getPageIndex(), pageInfo.getPageSize(), (int) Math.ceil((double) hits / pageInfo.getPageSize()), hits, resultList);
}

Example 2 with Predicate

use of org.jboss.pnc.spi.datastore.repositories.api.Predicate in project pnc by project-ncl.

the class BuildProviderImpl method getByAttribute.

public Page<Build> getByAttribute(BuildPageInfo buildPageInfo, Map<String, String> attributeConstraints) {
    Set<Predicate<BuildRecord>> predicates = new HashSet<>();
    for (Map.Entry<String, String> entry : attributeConstraints.entrySet()) {
        String key = entry.getKey();
        String value = entry.getValue();
        if (key.startsWith("!")) {
            predicates.add(withoutAttribute(key.substring(1)));
        } else {
            predicates.add(withAttribute(key, value));
        }
    }
    Predicate<BuildRecord> queryPredicate = rsqlPredicateProducer.getCriteriaPredicate(BuildRecord.class, buildPageInfo.getQ());
    predicates.add(queryPredicate);
    Predicate<BuildRecord>[] predicatesArray = predicates.toArray(new Predicate[predicates.size()]);
    PageInfo pageInfo = toPageInfo(buildPageInfo);
    SortInfo sortInfo = rsqlPredicateProducer.getSortInfo(type, buildPageInfo.getSort());
    List<BuildRecord> resultList = ((BuildRecordRepository) BuildProviderImpl.this.repository).queryWithPredicatesUsingCursor(pageInfo, sortInfo, predicatesArray);
    int hits = repository.count(predicatesArray);
    return new Page<>(buildPageInfo.getPageIndex(), buildPageInfo.getPageSize(), hits, resultList.stream().map(b -> mapper.toDTO(b)).collect(Collectors.toList()));
}

Example 3 with Predicate

use of org.jboss.pnc.spi.datastore.repositories.api.Predicate in project pnc by project-ncl.

the class ArtifactProviderImpl method getAllFiltered.

@Override
public Page<ArtifactInfo> getAllFiltered(int pageIndex, int pageSize, Optional<String> identifierPattern, Set<ArtifactQuality> qualities, Optional<RepositoryType> repoType, Set<BuildCategory> buildCategories) {
    CriteriaBuilder cb = em.getCriteriaBuilder();
    CriteriaQuery<Tuple> query = artifactInfoQuery(cb, identifierPattern, qualities, repoType, buildCategories);
    int offset = pageIndex * pageSize;
    List<ArtifactInfo> artifacts = em.createQuery(query).setMaxResults(pageSize).setFirstResult(offset).getResultList().stream().map(this::mapTupleToArtifactInfo).collect(Collectors.toList());
    Predicate<Artifact>[] predicates = getPredicates(identifierPattern, qualities, repoType, buildCategories);
    int totalHits = repository.count(predicates);
    int totalPages = (totalHits + pageSize - 1) / pageSize;
    return new Page<>(pageIndex, pageSize, totalPages, totalHits, artifacts);
