Class DSpaceCSV

  • All Implemented Interfaces:
    Serializable
    public class DSpaceCSV
extends Object
implements Serializable
    Utility class to read and write CSV files ************** Important Note ************** This class has been made serializable, as it is stored in a Session. Is it wise to: a) be putting this into a user's session? b) holding an entire CSV upload in memory?
