Connector Provider

Writing the Connector Provider

Each connector provider implements the following interface:


There is a base class that provides much of the implementation for a connector provider.


This assumes:

  • There is a single connector implementation class for the connector.
  • The connector is instantiated with the default constructor. This means all of its configuration information is contained in the Connection object supplied on the initialize() method.

If your connector implementation matches these requirements, its connector provider implementation need only implement a constructor to configure the base class's function with details of itself and the Java class of the connector it needs using:

  • a GUID for the connector type
  • a name for the connector type.
  • a description of what the connector is for and how to configure it.
  • the connector class it instantiates.
  • a list of the additional properties, configuration properties and secured properties needed to configure instances of the connector.
  • a description of the connector for its audit log (if the connector implements AuditLoggingComponent).
 * XXXStoreProvider is the OCF connector provider for the XXX connector.
public class XXXStoreProvider extends ConnectorProviderBase
     * Unique identifier of the connector for the audit log.
    private static final int    connectorComponentId   = 10001; /* Add unique number here */

     * Unique identifier for the connector type.
    private static final String connectorTypeGUID      = "Add unique GUID here";

     * Descriptive information about the connector for the connector type and audit log.
    private static final String connectorQualifiedName = "MyOrg:XXXStoreConnector";
    private static final String connectorDisplayName   = "XXX Store Connector";
    private static final String connectorDescription   = "Connector supports ... add details here.";
    private static final String connectorWikiPage      = "Add url to documentation here";

     * Define the name of the connector implementation.
    private static final Class<?> connectorClass = XXXStoreConnector.class;

     * Define the name of configuration properties.
    public static final String TEMPLATE_QUALIFIED_NAME_CONFIGURATION_PROPERTY = "templateQualifiedName";

     * Constructor used to initialize the ConnectorProviderBase class.
    public XXXStoreProvider()

         * Set up the class name of the connector that this provider creates.

         * Set up the connector type that should be included in a connection used to configure this connector.
        ConnectorType connectorType = new ConnectorType();

        List<String> recognizedConfigurationProperties = new ArrayList<>();

        super.connectorTypeBean = connectorType;

         * Set up the component description used in the connector's audit log messages.
        AuditLogReportingComponent componentDescription = new AuditLogReportingComponent();



Example: connector provider for the Kafka Monitor Integration Connector

For example, the KafkaMonitorIntegrationProvider is used to instantiate connectors that are monitoring an Apache Kafka broker. Therefore, its name and description refer to Kafka, and the connectors it instantiates are of type `KafkaMonitorIntegrationConnector .
