Parameters:

connectorName - name of associated connector

sourceName - source of the pathname

pathName - pathname to the directory

catalogTargetGUID - optional catalog target GUID

deleteMethod - should the connector use delete or archive?

templates - names and GUIDs of templates

configurationProperties - parameters to further modify the behaviour of the connector

integrationConnector - associated connector

dataFolderElement - Egeria element for this directory

auditLog - logging destination

Method Details

refresh

public void refresh()
             throws ConnectorCheckedException

Requests that the connector does a comparison of the metadata in the third party technology and open metadata repositories. Refresh is called when the integration connector first starts and then at intervals defined in the connector's configuration as well as any external REST API calls to explicitly refresh the connector.
This method performs two sweeps. It first retrieves the files in the directory and validates that are in the catalog - adding or updating them if necessary. The second sweep is to ensure that all the assets catalogued in this directory actually exist on the file system.

Specified by:

refresh in class DirectoryToMonitor

Throws:

ConnectorCheckedException - there is a problem with the connector. It is not able to refresh the metadata.
