Constructor Details

RelationshipMapping

public RelationshipMapping(XtdbOMRSRepositoryConnector xtdbConnector,
 org.odpi.openmetadata.repositoryservices.connectors.stores.metadatacollectionstore.properties.instances.Relationship relationship)

Construct a mapping from a Relationship (to map to a XTDB representation).

Parameters:

xtdbConnector - connectivity to XTDB

relationship - from which to map

RelationshipMapping

public RelationshipMapping(XtdbOMRSRepositoryConnector xtdbConnector,
 xtdb.api.XtdbDocument xtdbDoc,
 xtdb.api.IXtdbDatasource db)

Construct a mapping from a XTDB map (to map to an Egeria representation).

Parameters:

xtdbConnector - connectivity to XTDB

xtdbDoc - from which to map

db - an open database connection for a point-in-time appropriate to the mapping

Method Details

toEgeria

public org.odpi.openmetadata.repositoryservices.connectors.stores.metadatacollectionstore.properties.instances.Relationship toEgeria()
