Method Detail

reHomeInstance

protected static clojure.lang.IPersistentMap reHomeInstance(String userId,
                                                            clojure.lang.IPersistentMap existing,
                                                            String newHomeMetadataCollectionId,
                                                            String newHomeMetadataCollectionName)

Makes the necessary changes to update a metadata instance's home metadata repository.

Parameters:

userId - doing the update

existing - metadata instance

newHomeMetadataCollectionId - unique identifier of the instance's new home

newHomeMetadataCollectionName - name of the instance's new home

Returns:

IPersistentMap giving the updated instance representation

validate

protected static void validate(clojure.lang.IPersistentMap existing,
                               String metadataCollectionId,
                               String className,
                               String methodName)
                        throws org.odpi.openmetadata.repositoryservices.ffdc.exception.InvalidParameterException

Validate the re-home. The instance must originate in the liocal cohort and NOT be locally homed already, or the entity must have an instanceProvenanceType set to external and a replicatedBy that is NOT the local metadataCollectionId. Any other combination indicates a non-reference copy, and therefore cannot be re-homed.

Parameters:

existing - metadata instance

metadataCollectionId - of the metadata instance

className - calling class

methodName - calling method

Throws:

org.odpi.openmetadata.repositoryservices.ffdc.exception.InvalidParameterException - if the instance cannot be re-homed
