Example 1 with ConstraintDescriptor

use of com.emc.storageos.db.client.constraint.ConstraintDescriptor in project coprhd-controller by CoprHD.

the class GeoServiceClient method queryByConstraint.

/**
 * Query the GeoVisible resources by conditions
 *
 * @param constraint the query condition
 * @param result the query result
 * @return list of resources
 * @throws Exception
 */
@SuppressWarnings("unchecked")
public <T> void queryByConstraint(Constraint constraint, QueryResultList<T> result) throws Exception {
    ConstraintDescriptor constrainDescriptor = constraint.toConstraintDescriptor();
    WebResource rRoot = createRequest(GEOVISIBLE_URI + "constraint/" + result.getClass().getName());
    rRoot.accept(MediaType.APPLICATION_OCTET_STREAM);
    ClientResponse resp = addSignature(rRoot).post(ClientResponse.class, constrainDescriptor);
    InputStream input = resp.getEntityInputStream();
    ObjectInputStream objInputStream = new ObjectInputStream(input);
    ResourcesResponse<?> resources = (ResourcesResponse<?>) objInputStream.readObject();
    List<Object> queryResult = (List<Object>) resources.getObjects();
    List<T> ret = new ArrayList<T>();
    for (Object obj : queryResult) {
        ret.add((T) obj);
