        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.output.BaseOutputConnector
        Parameters:
        spec - 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.
        Throws:
        org.apache.manifoldcf.core.interfaces.ManifoldCFException
        org.apache.manifoldcf.agents.interfaces.ServiceInterruption

        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.
        Specified by:
        addOrReplaceDocumentWithException in interface org.apache.manifoldcf.agents.interfaces.IPipelineConnector
        Overrides:
        addOrReplaceDocumentWithException in class org.apache.manifoldcf.agents.output.BaseOutputConnector
        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 - includes 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.

        Remove a document using the connector. Note that the last outputDescription is included, since it may be necessary for the connector to use such information to know how to properly remove the document.

        out - is the output to which any HTML should be sent.
        locale - is the preferred local of the output.
        os - is the current pipeline specification for this job.
        connectionSequenceNumber - is the unique number of this connection within the job.

        Process a specification post. This method is called at the start of job's edit or view page, whenever there is a possibility that form data for a connection has been posted. Its purpose is to gather form information and modify the transformation specification accordingly. The name of the posted form is "editjob".
        Specified by:
        processSpecificationPost in interface org.apache.manifoldcf.agents.interfaces.IPipelineConnector
