Example 1 with PagingErrorException

use of org.odpi.openmetadata.repositoryservices.ffdc.exception.PagingErrorException in project egeria-connector-sas-viya by odpi.

the class MetadataCollection method getEntityNeighborhood.

/**
 * Return the entities and relationships that radiate out from the supplied entity GUID.
 * The results are scoped both the instance type guids and the level.
 *
 * @param userId unique identifier for requesting user.
 * @param entityGUID the starting point of the query.
 * @param entityTypeGUIDs list of entity types to include in the query results.  Null means include
 *                          all entities found, irrespective of their type.
 * @param relationshipTypeGUIDs list of relationship types to include in the query results.  Null means include
 *                                all relationships found, irrespective of their type.
 * @param limitResultsByStatus By default, relationships in all non-DELETED statuses are returned.  However, it is possible
 *                             to specify a list of statuses (eg ACTIVE) to restrict the results to.  Null means all
 *                             status values except DELETED.
 * @param limitResultsByClassification List of classifications that must be present on all returned entities.
 * @param asOfTime Requests a historical query of the relationships for the entity.  Null means return the
 *                 present values.
 * @param level the number of the relationships out from the starting entity that the query will traverse to
 *              gather results.
 * @return InstanceGraph the sub-graph that represents the returned linked entities and their relationships.
 * @throws InvalidParameterException one of the parameters is invalid or null.
 * @throws TypeErrorException the type guid passed on the request is not known by the
 *                              metadata collection.
 * @throws RepositoryErrorException there is a problem communicating with the metadata repository where
 *                                  the metadata collection is stored.
 * @throws EntityNotKnownException the entity identified by the entityGUID is not found in the metadata collection.
 * @throws PropertyErrorException there is a problem with one of the other parameters.
 * @throws FunctionNotSupportedException the repository does not support this call.
 * @throws UserNotAuthorizedException the userId is not permitted to perform this operation.
