Method Details

migrate

public IdbMigrationStrategy.MigrationResult migrate(MigrationContext context)
                                             throws MigrationException

Description copied from interface: IdbMigrationStrategy

Migrate records from the internal database to the configuration resource collection. To do this, use the given session to issue an SQuery to find the records you want to migrate. Then compile a list of ChangeOperation that will be applied to the config resource collection to add the appropriate resources.

Specified by:

migrate in interface IdbMigrationStrategy

Parameters:

context - a MigrationContext which provides methods for accessing a PersistenceSession to query the internal DB as well as a ConfigurationManager for accessing the new config resource APIs

Returns:

A list of change operations that will be applied to the config resource collection.

Throws:

MigrationException - If an error occurs during migration.

getRecordMetas

public List<SRecordMeta<? extends SRecordInstance>> getRecordMetas()

Specified by:

getRecordMetas in interface IdbMigrationStrategy

Returns:

The record metas that this strategy migrates, if any. If this strategy does not migrate records, return an empty list. Also note that any record metas returned here will automatically be applied to the SchemaUpdater.updatePersistentRecords(Iterable), so you do not need to do this again in your GatewayModuleHook setup() method.

getStrategyName

public @NonNull String getStrategyName()

Description copied from interface: IdbMigrationStrategy

A human-readable name for this migration strategy to use in the migration log.

Specified by:

getStrategyName in interface IdbMigrationStrategy
