        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.

        View specification. This method is called in the body section of a job's view page. Its purpose is to present the pipeline specification information to the user. The coder can presume that the HTML that is output from this configuration will be within appropriate <html> and <body>tags.
        Specified by:
        viewSpecification in interface org.apache.manifoldcf.agents.interfaces.IPipelineConnector
        Overrides:
        viewSpecification in class org.apache.manifoldcf.agents.transformation.BaseTransformationConnector
        Parameters:
        out - is the output to which any HTML should be sent.
        locale - is the preferred local of the output.
        connectionSequenceNumber - is the unique number of this connection within the job.
        os - is the current pipeline specification for this job.
        Throws:
        org.apache.manifoldcf.core.interfaces.ManifoldCFException
