        Specified by:
        getActivitiesList in interface org.apache.manifoldcf.agents.interfaces.ITransformationConnector
        Overrides:

        Get a pipeline version string, given a pipeline specification object. The version string is used to uniquely describe the pertinent details of the specification and the configuration, to allow the Connector Framework to determine whether a document will need to be processed again. Note that the contents of any document cannot be considered by this method; only configuration and specification information can be considered. This method presumes that the underlying connector object has been configured.
        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 pipeline specification object for this connection for the job that is doing the crawling.
        Returns:
        a string, of unlimited length, which uniquely describes configuration and specification in such a way that if two such strings are equal, nothing that affects how or whether the document is indexed will be different.

                                             java.io.IOException
        Add (or replace) a document in the output data store using the connector. 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. The OutputSpecification is *not* provided to this method, because the goal is consistency, and if output is done it must be consistent with the output description, since that was what was partly used to determine if output should be taking place. So it may be necessary for this method to decode an output description string in order to determine what should be done.
        Specified by:
        addOrReplaceDocumentWithException in interface org.apache.manifoldcf.agents.interfaces.IPipelineConnector
        Overrides:
        addOrReplaceDocumentWithException in class org.apache.manifoldcf.agents.transformation.BaseTransformationConnector
        Parameters:
        documentURI - is the URI of the document. The URI is presumed to be the unique identifier which the output data store will use to process and serve the document. This URI is constructed by the repository connector which fetches the document, and is thus universal across all output connectors.
        pipelineDescription - is the description string that was constructed for this document by the getOutputDescription() method.
        document - is the document data to be processed (handed to the output data store).
        authorityNameString - is the name of the authority responsible for authorizing any access tokens passed in with the repository document. May be null.
        activities - is the handle to an object that the implementer of a pipeline connector may use to perform operations, such as logging processing activity, or sending a modified document to the next stage in the pipeline.
        Returns:
        the document status (accepted or permanently rejected).
        Throws:
        java.io.IOException - only if there's a stream error reading the document data.
