Method Details

start

public void start()
           throws ConnectorCheckedException

Indicates that the connector is completely configured and can begin processing. This call can be used to register with non-blocking services.

Specified by:

start in interface IntegrationConnector

Overrides:

start in class ConnectorBase

Throws:

ConnectorCheckedException - there is a problem within the connector.

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.

Specified by:

refresh in interface IntegrationConnector

Throws:

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

processEvent

public void processEvent(AssetManagerOutTopicEvent event)

Process an event that was published by the Asset Manager OMAS. This connector is only interested in glossaries, glossary categories and glossary terms. The listener is only registered if metadata is flowing from the open metadata ecosystem to Apache Atlas.

Specified by:

processEvent in interface AssetManagerEventListener

Parameters:

event - event object

disconnect

public void disconnect()
                throws ConnectorCheckedException

Shutdown Apache Atlas monitoring

Specified by:

disconnect in interface IntegrationConnector

Overrides:

disconnect in class IntegrationConnectorBase

Throws:

ConnectorCheckedException - something failed in the super class
