process

public java.lang.String[] process(Blackboard blackboard,
                                  java.lang.String[] recordIds)
                           throws ProcessingException

process records on Blackboard service.

Parameters:

blackboard - Blackboard service managing the records.

recordIds - Ids of records to process.
