getActivitiesList

public java.lang.String[] getActivitiesList()

Return the list of activities that this connector supports (i.e. writes into the log).

Specified by:

getActivitiesList in interface org.apache.manifoldcf.agents.interfaces.IOutputConnector

Overrides:

getActivitiesList in class org.apache.manifoldcf.agents.output.BaseOutputConnector

Returns:

the list.

connect

public void connect(org.apache.manifoldcf.core.interfaces.ConfigParams configParameters)

Connect.

Specified by:

connect in interface org.apache.manifoldcf.core.interfaces.IConnector

Overrides:

connect in class org.apache.manifoldcf.core.connector.BaseConnector

Parameters:

configParameters - is the set of configuration parameters, which in this case describe the target appliance, basic auth configuration, etc. (This formerly came out of the ini file.)

disconnect

public void disconnect()
                throws org.apache.manifoldcf.core.interfaces.ManifoldCFException

Close the connection. Call this before discarding the connection.

Specified by:

disconnect in interface org.apache.manifoldcf.core.interfaces.IConnector

Overrides:

disconnect in class org.apache.manifoldcf.core.connector.BaseConnector

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

getSession

protected void getSession()
                   throws org.apache.manifoldcf.core.interfaces.ManifoldCFException,
                          org.apache.manifoldcf.agents.interfaces.ServiceInterruption

Set up a session

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

org.apache.manifoldcf.agents.interfaces.ServiceInterruption

check

public java.lang.String check()
                       throws org.apache.manifoldcf.core.interfaces.ManifoldCFException

Test the connection. Returns a string describing the connection integrity.

Specified by:

check in interface org.apache.manifoldcf.core.interfaces.IConnector

Overrides:

check in class org.apache.manifoldcf.core.connector.BaseConnector

Returns:

the connection's status as a displayable string.

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

getPipelineDescription

public org.apache.manifoldcf.core.interfaces.VersionContext getPipelineDescription(org.apache.manifoldcf.core.interfaces.Specification spec)
                                                                            throws org.apache.manifoldcf.core.interfaces.ManifoldCFException,
                                                                                   org.apache.manifoldcf.agents.interfaces.ServiceInterruption

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

addOrReplaceDocumentWithException

                                      throws org.apache.manifoldcf.core.interfaces.ManifoldCFException,
                                             org.apache.manifoldcf.agents.interfaces.ServiceInterruption,
                                             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.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.

outputDescription - 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 an output connector may use to perform operations, such as logging processing activity.

Returns:

the document status (accepted or permanently rejected).

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

                           org.apache.manifoldcf.agents.interfaces.ServiceInterruption

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.

Specified by:

Parameters:
