Class GroupDefinitionsFromCsv

java.lang.Object
  com.google.enterprise.adaptor.AbstractAdaptor
      com.google.enterprise.adaptor.examples.GroupDefinitionsFromCsv

All Implemented Interfaces:

Adaptor

public class GroupDefinitionsFromCsv
extends AbstractAdaptor

Reads memberships from CSV, forms groups, and sends to to GSA.

GroupDefinitionsFromCsv

public GroupDefinitionsFromCsv()

initConfig

public void initConfig(Config config)

Description copied from class: AbstractAdaptor

Provides the opportunity for the Adaptor to create new configuration values or override default values. Only Config.addKey(java.lang.String, java.lang.String) should likely be called. The user's configuration will override any values set in this way. This method is called by AbstractAdaptor.main(com.google.enterprise.adaptor.Adaptor, java.lang.String[]) before Adaptor.init(com.google.enterprise.adaptor.AdaptorContext) is called.

This implementation does nothing.

Specified by:

initConfig in interface Adaptor

Overrides:

initConfig in class AbstractAdaptor

init

public void init(AdaptorContext context)
          throws Exception

Description copied from class: AbstractAdaptor

Initialize adaptor with the current context. This is the ideal time to start any threads to do extra behind-the-scenes work. The context points to other useful objects that can be used at any time. For example, methods on DocIdPusher provided via AdaptorContext.getDocIdPusher() are allowed to be called whenever the Adaptor wishes. This allows doing event-based incremental pushes at any time.

The method is called at the end of GsaCommunicationHandler.start().

If you experience a fatal error during initialization, feel free to throw an Exception to cancel the startup process.

This implementation does nothing.

Specified by:

init in interface Adaptor

Overrides:

init in class AbstractAdaptor

Throws:

Exception

getDocIds

public void getDocIds(DocIdPusher pusher)
               throws InterruptedException,
                      IOException

Description copied from interface: Adaptor

Pushes all the DocIds that are suppose to be indexed by the GSA. This will frequently involve re-sending DocIds to the GSA, but this allows healing previous errors and cache inconsistencies. Re-sending DocIds is very fast and should be considered free on the GSA. This method should determine a list of DocIds to push and call DocIdPusher.pushDocIds(java.lang.Iterable) one or more times and DocIdPusher.pushNamedResources(java.util.Map) if using named resources.

pusher is provided as convenience and is the same object provided to Adaptor.init(com.google.enterprise.adaptor.AdaptorContext) previously. This method may take a while and implementations are free to call Thread.sleep(long) occasionally to reduce load.

If you experience a fatal error, feel free to throw an IOException or RuntimeException. In the case of an error, the ExceptionHandler in use in AdaptorContext will determine if and when to retry.

Throws:

InterruptedException

IOException

getDocContent

public void getDocContent(Request req,
                          Response res)
                   throws IOException

Description copied from interface: Adaptor

Provides contents and metadata of particular document. This method should be highly parallelizable and support twenty or more concurrent calls. Two to three concurrent calls may be average during initial GSA crawling, but twenty or more concurrent calls is typical when the GSA is recrawling unmodified content.

If you experience a fatal error, feel free to throw an IOException or RuntimeException. In the case of an error, the GSA will determine if and when to retry.

Throws:

IOException

public static void main(String[] args)
