OpenMetadataTopicListenerConnectorBase is a base class for a connector that is going to embed the OpenMetadataTopicConnector and register a listener with it. It manages the instances of the OpenMetadataTopicConnector as they are passed as a list of connectors from the ConnectorBroker and registers itself with the OpenMetadataTopicConnector. Subclasses just need to manage their list of listeners and override the processEvent() method. When it is called, the subclass

    • initializeEmbeddedConnectors

      public void initializeEmbeddedConnectors(List<org.odpi.openmetadata.frameworks.connectors.Connector> embeddedConnectors)
      Set up the list of connectors that this virtual connector will use to support its interface. The connectors are initialized waiting to start. When start() is called on the virtual connector, it needs to pass start() to each of the embedded connectors. Similarly for disconnect().
      Specified by:
      initializeEmbeddedConnectors in interface org.odpi.openmetadata.frameworks.connectors.VirtualConnectorExtension
      Overrides:
      initializeEmbeddedConnectors in class OpenMetadataTopicConsumerBase
      Parameters:
      embeddedConnectors - list of connectors

    • processEvent

      public abstract void processEvent(String event)
      Method to pass an event received on topic.
      Specified by:
      processEvent in interface OpenMetadataTopicListener
      Parameters:
      event - inbound event

    • disconnect

      public void disconnect() throws org.odpi.openmetadata.frameworks.connectors.ffdc.ConnectorCheckedException
      Free up any resources held since the connector is no longer needed.
      Overrides:
      disconnect in class OpenMetadataTopicConsumerBase
      Throws:
      org.odpi.openmetadata.frameworks.connectors.ffdc.ConnectorCheckedException - there is a problem within the connector.
