Class OpenMetadataStoreClient

  • All Implemented Interfaces:
    OpenMetadataStore
    public class OpenMetadataStoreClient
extends OpenMetadataClient
    OpenMetadataClient is created for each instance of the governance service. It interfaces between the governance context of each governance service instance and the clients and handlers of Governance Action Open Metadata Engine Service (OMES). The governanceServiceHandler is also tied to the governance service instance. The governanceListenerManager and the governanceEngineClient are shared by all services instances running in the Governance Action OMES. There are three groups of methods:
    • Methods for working with metadata that are driven by the logic in the governance service. This is implemented with calls to the Governance Engine OMAS client that is calling the partner OMAS for Governance Action OMES.
    • Methods for managing the Governance Actions that drive calls to the governance services. These methods are passed to the governanceServiceHandler to be handled by the engine host services. The engine host services may have a different partner OMAS and so they have their own client to Governance Engine OMAS.
    • Methods for managing Open Watchdog Governance Service's listeners that are passed to the governance listener manager.

      • registerListener

        public void registerListener​(WatchdogGovernanceListener listener,
                             List<WatchdogEventType> interestingEventTypes,
                             List<String> interestingMetadataTypes,
                             String specificInstance)
                      throws InvalidParameterException
        Register a listener to receive events about changes to metadata elements in the open metadata store. There can be only one registered listener. If this method is called more than once, the new parameters replace the existing parameters. This means the watchdog governance action service can change the listener and the parameters that control the types of events received while it is running. The types of events passed to the listener are controlled by the combination of the interesting event types and the interesting metadata types. That is an event is only passed to the listener if it matches both the interesting event types and the interesting metadata types. If specific instance, interestingEventTypes or interestingMetadataTypes are null, it defaults to "any". If the listener parameter is null, no more events are passed to the listener.
        Specified by:
        registerListener in class OpenMetadataClient
        Parameters:
        listener - listener object to receive events
        interestingEventTypes - types of events that should be passed to the listener
        interestingMetadataTypes - types of elements that are the subject of the interesting event types
        specificInstance - unique identifier of a specific instance to watch for
        Throws:
        InvalidParameterException - one or more of the type names are unrecognized
