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.

Throws:

                                             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.

Output the specification header section. This method is called in the head section of a job page which has selected a pipeline connection of the current type. Its purpose is to add the required tabs to the list, and to output any javascript methods that might be needed by the job editing HTML.

Specified by:

outputSpecificationHeader in interface org.apache.manifoldcf.agents.interfaces.IPipelineConnector

Overrides:

outputSpecificationHeader 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.

os - is the current pipeline specification for this connection.

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

tabsArray - is an array of tab names. Add to this array any tab names that are specific to the connector.

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

java.io.IOException

                             throws org.apache.manifoldcf.core.interfaces.ManifoldCFException,
                                    java.io.IOException

Output the specification body section. This method is called in the body section of a job page which has selected a pipeline connection of the current type. Its purpose is to present the required form elements for editing. The coder can presume that the HTML that is output from this configuration will be within appropriate <html>, <body>, and <form> tags. The name of the form is "editjob".

Specified by:

outputSpecificationBody in interface org.apache.manifoldcf.agents.interfaces.IPipelineConnector

Overrides:

outputSpecificationBody 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.

os - is the current pipeline specification for this job.

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

actualSequenceNumber - is the connection within the job that has currently been selected.

tabName - is the current tab name.

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

java.io.IOException

                                          throws org.apache.manifoldcf.core.interfaces.ManifoldCFException

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

Overrides:

processSpecificationPost in class org.apache.manifoldcf.agents.transformation.BaseTransformationConnector

Parameters:

variableContext - contains the post data, including binary file-upload information.

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.

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

                              java.io.IOException

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:
