        Return a list of activities that this connector generates. The connector does NOT need to be connected before this method is called.
        Specified by:

        Overrides:

        Get an output version string, given an output specification. The output version string is used to uniquely describe the pertinent details of the output specification and the configuration, to allow the Connector Framework to determine whether a document will need to be output again. Note that the contents of the document cannot be considered by this method, and that a different version string (defined in IRepositoryConnector) is used to describe the version of the actual document. This method presumes that the connector object has been configured, and it is thus able to communicate with the output data store should that be necessary.
        Specified by:
        getPipelineDescription in interface org.apache.manifoldcf.agents.interfaces.IPipelineConnector
        Overrides:
        getPipelineDescription in class org.apache.manifoldcf.agents.transformation.BaseTransformationConnector
        Parameters:
        os - is the current output specification for the job that is doing the crawling.
        Returns:
        a string, of unlimited length, which uniquely describes output configuration and specification in such a way that if two such strings are equal, the document will not need to be sent again to the output data store.
