All Implemented Interfaces:

Serializable

@Named
@RequestScoped

@Produces({"text/html","application/xml","application/json","text/xml"})
public class SnapshotRestService
extends Object
implements Serializable

The SnapshotRestService provides a Rest API to access the snapshot data.

The method getWorkitemFile is a wrapper for the WorkflowRestService and returns the file content based on the $uniqueid of the origin workitem.

The method getDocumentsBySyncPoint returns snapshot data from a given modified timestamp. This method is used by an external archive service to sync the snapshot data.

In case the environment variable 'ARCHIVE_SERVICE_ENDPOINT' is set the file content is fetched directly form the Cassandra archive.
