GetEntityNeighborhood

public GetEntityNeighborhood(XtdbOMRSRepositoryConnector xtdb,
                             String entityGUID,
                             List<String> entityTypeGUIDs,

                             int level)

Create a new getEntityNeighborhood operation.

Parameters:

xtdb - connectivity to XTDB

entityGUID - the starting point of the query

entityTypeGUIDs - list of entity types to include in the query results (null means include all entities found, irrespective of their type)

relationshipTypeGUIDs - list of relationship types to include in the query results (null means include all relationships found, irrespective of their type)

limitResultsByStatus - list of statuses by which to limit results

limitResultsByClassification - list of classifications that must be present on all returned entities

asOfTime - the point-in-time for which to retrieve results

level - the number of the relationships out from the starting entity the query will traverse to gather results

execute

public org.odpi.openmetadata.repositoryservices.connectors.stores.metadatacollectionstore.properties.instances.InstanceGraph execute()
                                                                                                                              throws org.odpi.openmetadata.repositoryservices.ffdc.exception.EntityNotKnownException,

Execute the getEntityNeighborhood operation.

Returns:

InstanceGraph of results

Throws:

org.odpi.openmetadata.repositoryservices.ffdc.exception.EntityNotKnownException - if the starting entity for the traversal cannot be found

org.odpi.openmetadata.repositoryservices.ffdc.exception.RepositoryErrorException - on any other connectivity or resource usage error
