Method Details

clone

public static ConnectionUtils.FlowFileCloneResult clone(FlowFileRecord flowFile,
 Collection<Connection> destinations,
 FlowFileRepository flowFileRepository,
 ContentRepository contentRepository)

Creates the FlowFileRecords and the RepositoryRecords necessary for transferring the given FlowFile to all of the given destinations. If only a single destination is given, the returned result will contain only the original FlowFile and a RepositoryRecord that represents that FlowFile. If multiple destinations are given, the returned result will contain the original FlowFile, as well as a cloned FlowFile for each of the destinations. If one or more clones are created, and a Content Repository is provided, the Claimant Count will be incremented for each clone (but not the original FlowFile). If the Content Repository is null, the Claimant Counts will not be incremented.

Parameters:

flowFile - the FlowFile to clone as necessary

destinations - the destinations that the FlowFile will be transferred to

flowFileRepository - the FlowFile Repository to use to generate the FlowFile ID for each clone

contentRepository - the Content Repository to use to increment the Claimant Count for each clone, or null if the caller will take on the responsibility of incrementing the Claimant Counts

Returns:

a FlowFileCloneResult that contains the FlowFiles to enqueue and the RepositoryRecords to create

createRepositoryRecord

private static RepositoryRecord createRepositoryRecord(FlowFileRecord flowFile,
 FlowFileQueue destinationQueue)
