GetRelationshipsForEntity

public GetRelationshipsForEntity(XtdbOMRSRepositoryConnector xtdb,
 String entityGUID,
 String relationshipTypeGUID,
 int fromRelationshipElement,

 xtdb.api.IXtdbDatasource existingDB,
 String sequencingProperty,
 org.odpi.openmetadata.repositoryservices.connectors.stores.metadatacollectionstore.properties.SequencingOrder sequencingOrder,
 int pageSize,
 String userId)

Create a new 'getRelationshipsForEntity' executable.

Parameters:

xtdb - connectivity to XTDB

entityGUID - of the entity for which to find relationships

relationshipTypeGUID - to limit the relationship types to retrieve (optional)

fromRelationshipElement - starting element for paging

limitResultsByStatus - by which to limit results (optional)

existingDB - already-opened datasource against which to do the retrievals

sequencingProperty - by which to order the results (required if sequencingOrder involves a property)

sequencingOrder - by which to order results (optional, will default to GUID)

pageSize - maximum number of results per page

userId - of the user running the query

Method Details

runQuery

protected Collection<List<?>> runQuery(xtdb.api.IXtdbDatasource db)
                                throws org.odpi.openmetadata.repositoryservices.ffdc.exception.TypeErrorException,
org.odpi.openmetadata.repositoryservices.ffdc.exception.RepositoryErrorException

Interface that must be implemented to actually execute the query logic.

Specified by:

runQuery in class AbstractSearchOperation

Parameters:

db - the datasource against which to run the query

Returns:

Collection<List<?>> of internal XT references (IDs) that match the query

Throws:

org.odpi.openmetadata.repositoryservices.ffdc.exception.TypeErrorException - if a requested type for searching is not known to the repository

org.odpi.openmetadata.repositoryservices.ffdc.exception.RepositoryErrorException - if there is any issue iterating through the results
