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.

connectionSequenceNumber - is the unique number of this connection within the job.

Returns:

null if all is well, or a string error message if there is an error that should prevent saving of the job (and cause a redirection to an error page).

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

viewSpecification

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.output.BaseOutputConnector

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
