Examples with Filter com.google.appengine.api.datastore.Query.Filter used on opensource projects

Example 21 with Filter

use of com.google.appengine.api.datastore.Query.Filter in project java-docs-samples by GoogleCloudPlatform.

the class QueriesTest method queryRestrictions_compositeFilter_isInvalid.

@Test
public void queryRestrictions_compositeFilter_isInvalid() throws Exception {
    long minBirthYear = 1940;
    long maxHeight = 200;
    // [START inequality_filters_one_property_invalid_example]
    Filter birthYearMinFilter = new FilterPredicate("birthYear", FilterOperator.GREATER_THAN_OR_EQUAL, minBirthYear);
    Filter heightMaxFilter = new FilterPredicate("height", FilterOperator.LESS_THAN_OR_EQUAL, maxHeight);
    Filter invalidFilter = CompositeFilterOperator.and(birthYearMinFilter, heightMaxFilter);
    Query q = new Query("Person").setFilter(invalidFilter);
// [END inequality_filters_one_property_invalid_example]
// Note: The local devserver behavior is different than the production
// version of Cloud Datastore, so there aren't any assertions we can make
// in this test.  The query appears to work with the local test runner,
// but will fail in production.
}
