Constructor Details

ApacheAtlasIntegrationTargetProcessor

public ApacheAtlasIntegrationTargetProcessor(CatalogTarget catalogTarget,
 CatalogTargetContext catalogTargetContext,
 Connector connectorToTarget,
 String connectorName,
 AuditLog auditLog)

Constructor

Parameters:

catalogTarget - catalog target information

catalogTargetContext - specialized context for this catalog target

connectorToTarget - connector to access the target resource

connectorName - name of this integration connector

auditLog - logging destination

Method Details

start

public void start()
           throws ConnectorCheckedException,
UserNotAuthorizedException

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

Overrides:

start in class CatalogTargetProcessorBase

Throws:

ConnectorCheckedException - the connector detected a problem.

UserNotAuthorizedException - the connector was disconnected before/during start

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.

Overrides:

refresh in class CatalogTargetProcessorBase

Throws:

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

processEvent

public void processEvent(OpenMetadataOutTopicEvent 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 OpenMetadataEventListener

Parameters:

event - event object

disconnect

public void disconnect()
                throws ConnectorCheckedException

Shutdown Apache Atlas monitoring

Overrides:

disconnect in class CatalogTargetProcessorBase

Throws:

ConnectorCheckedException - something failed in the super class
