Examples with QuerySpec org.eclipse.dataspaceconnector.spi.query.QuerySpec used on opensource projects

Example 1 with QuerySpec

use of org.eclipse.dataspaceconnector.spi.query.QuerySpec in project DataSpaceConnector by eclipse-dataspaceconnector.

the class InMemoryPolicyStoreTest method findAll_allFilters.

@Test
void findAll_allFilters() {
    Policy policy1 = Policy.Builder.newInstance().target("target1").id("1C").build();
    Policy policy2 = Policy.Builder.newInstance().target("target1").id("1A").build();
    Policy policy3 = Policy.Builder.newInstance().target("target1").id("1B").build();
    Policy policyX = Policy.Builder.newInstance().target("target2").id("2X").build();
    Policy policyY = Policy.Builder.newInstance().target("target2").id("2Y").build();
    store.save(policy1);
    store.save(policy2);
    store.save(policy3);
    store.save(policyX);
    store.save(policyY);
    QuerySpec uid = QuerySpec.Builder.newInstance().filter("target=target1").sortField("uid").sortOrder(SortOrder.DESC).offset(1).limit(1).build();
    assertThat(store.findAll(uid)).containsExactly(policy3);
}

Example 2 with QuerySpec

use of org.eclipse.dataspaceconnector.spi.query.QuerySpec in project DataSpaceConnector by eclipse-dataspaceconnector.

the class SqlAssetIndex method queryAssets.

@Override

    Objects.requireNonNull(querySpec);
    var conditions = querySpec.getFilterExpression().stream().map(SqlConditionExpression::new).collect(Collectors.toList());
    var results = conditions.stream().map(SqlConditionExpression::isValidExpression).collect(Collectors.toList());
    if (results.stream().anyMatch(Result::failed)) {
        var message = results.stream().flatMap(r -> r.getFailureMessages().stream()).collect(Collectors.joining(", "));
        throw new IllegalArgumentException(message);
    }
    var subSelects = conditions.stream().map(this::toSubSelect).collect(Collectors.toList());
    var template = "%s %s LIMIT %s OFFSET %s";
    var query = format(template, sqlAssetQueries.getSqlAssetListClause(), concatSubSelects(subSelects), querySpec.getLimit(), querySpec.getOffset());
    return transactionContext.execute(() -> {
        try (var connection = getConnection()) {
            var params = conditions.stream().flatMap(SqlConditionExpression::toStatementParameter).collect(Collectors.toList());
            List<String> ids = executeQuery(connection, this::mapAssetIds, query, params.toArray(Object[]::new));
            return ids.stream().map(this::findById);
        } catch (SQLException e) {
            throw new EdcPersistenceException(e);
        }
    });
