public abstract class GovernanceActionService
extends ConnectorBase
implements AuditLoggingComponent

GovernanceActionService describes the base class for a specific type of connector that is responsible for preforming specific governance actions on demand. There are five types of governance action service:

• WatchdogGovernanceActionService - monitors for changes to the metadata elements and initiates other governance actions depending on the nature of the change.
• VerificationGovernanceActionService - tests values in the metadata elements to detect errors or to classify the status of the metadata elements.
• TriageGovernanceActionService - manages the choices on how to resolve a situation, often involving a human decision maker.
• RemediationGovernanceActionService - maintains the metadata elements.
• ProvisioningGovernanceActionService - provisions resources in the digital landscape and maintains lineage.

Each type of governance action service is passed a specialize context that provides it with the metadata methods it needs for its specific role. When you build a governance action service, you extend the governance action service class that matches the purpose of your governance action to ensure your code receives a context with the appropriate interface.

                                         Throwable error)
                                  throws ConnectorCheckedException

Provide a common exception for unexpected errors.

Parameters:

methodName - calling method

error - caught exception

Throws:

GovernanceServiceException - wrapped exception

ConnectorCheckedException

validateContext

public void validateContext(GovernanceContext governanceContext)
                     throws ConnectorCheckedException

Verify that the context has been set up in the subclass

Parameters:

governanceContext - context from the subclass

Throws:
