public class FlowUtils
extends Object

This is a utility class to aid in the submission flow scripts. Since data validation is cumbersome inside a flow script this is a collection of methods to perform processing at each step of the flow, the flow script will ties these operations together in a meaningful order but all actually processing is done through these various processes.

setPageReached

public static void setPageReached(Context context,
                  String id,

Indicate the user has advanced to the given page within a given step. This will only actually do anything when it's a user initially entering a submission. It will increase the "stage reached" and "page reached" columns - it will not "set back" where a user has reached.

Parameters:

context - The current DSpace content

id - The unique ID of the current workflow/workspace

step - the step the user has just reached

page - the page (within the step) the user has just reached

Throws:

SQLException

AuthorizeException

IOException
