org.apache.manifoldcf.crawler.connectors.BaseRepositoryConnector

org.apache.manifoldcf.crawler.connectors.filesystem.FileConnector

All Implemented Interfaces:

org.apache.manifoldcf.core.interfaces.IConnector, org.apache.manifoldcf.crawler.interfaces.IRepositoryConnector

public class FileConnector
extends org.apache.manifoldcf.crawler.connectors.BaseRepositoryConnector

This is the "repository connector" for a file system. It's a relative of the share crawler, and should have comparable basic functionality, with the exception of the ability to use ActiveDirectory and look at other shares.

                                         org.apache.manifoldcf.agents.interfaces.ServiceInterruption

Queue "seed" documents. Seed documents are the starting places for crawling activity. Documents are seeded when this method calls appropriate methods in the passed in ISeedingActivity object. This method can choose to find repository changes that happen only during the specified time interval. The seeds recorded by this method will be viewed by the framework based on what the getConnectorModel() method returns. It is not a big problem if the connector chooses to create more seeds than are strictly necessary; it is merely a question of overall work required. The end time and seeding version string passed to this method may be interpreted for greatest efficiency. For continuous crawling jobs, this method will be called once, when the job starts, and at various periodic intervals as the job executes. When a job's specification is changed, the framework automatically resets the seeding version string to null. The seeding version string may also be set to null on each job run, depending on the connector model returned by getConnectorModel(). Note that it is always ok to send MORE documents rather than less to this method. The connector will be connected before this method can be called.

Specified by:

addSeedDocuments in interface org.apache.manifoldcf.crawler.interfaces.IRepositoryConnector

Overrides:

addSeedDocuments in class org.apache.manifoldcf.crawler.connectors.BaseRepositoryConnector

Parameters:

activities - is the interface this method should use to perform whatever framework actions are desired.

spec - is a document specification (that comes from the job).

seedTime - is the end of the time range of documents to consider, exclusive.

lastSeedVersion - is the last seeding version string for this job, or null if the job has no previous seeding version string.

jobMode - is an integer describing how the job is being run, whether continuous or once-only.

Returns:

an updated seeding version string, to be stored with the job.

Throws:

org.apache.manifoldcf.core.interfaces.ManifoldCFException

org.apache.manifoldcf.agents.interfaces.ServiceInterruption

                             org.apache.manifoldcf.agents.interfaces.ServiceInterruption

Process a set of documents. This is the method that should cause each document to be fetched, processed, and the results either added to the queue of documents for the current job, and/or entered into the incremental ingestion manager. The document specification allows this class to filter what is done based on the job. The connector will be connected before this method can be called.

Specified by:

processDocuments in interface org.apache.manifoldcf.crawler.interfaces.IRepositoryConnector

Overrides:

processDocuments in class org.apache.manifoldcf.crawler.connectors.BaseRepositoryConnector

Parameters:

documentIdentifiers - is the set of document identifiers to process.

statuses - are the currently-stored document versions for each document in the set of document identifiers passed in above.

activities - is the interface this method should use to queue up new document references and ingest documents.

jobMode - is an integer describing how the job is being run, whether continuous or once-only.

usesDefaultAuthority - will be true only if the authority in use for these documents is the default one.
