Class WorkflowManager

java.lang.Object
  org.dspace.workflow.WorkflowManager

public class WorkflowManager
extends Object

Workflow state machine Notes: Determining item status from the database: When an item has not been submitted yet, it is in the user's personal workspace (there is a row in PersonalWorkspace pointing to it.) When an item is submitted and is somewhere in a workflow, it has a row in the WorkflowItem table pointing to it. The state of the workflow can be determined by looking at WorkflowItem.getState() When a submission is complete, the WorkflowItem pointing to the item is destroyed and the archive() method is called, which hooks the item up to the archive. Notification: When an item enters a state that requires notification, (WFSTATE_STEP1POOL, WFSTATE_STEP2POOL, WFSTATE_STEP3POOL,) the workflow needs to notify the appropriate groups that they have a pending task to claim. Revealing lists of approvers, editors, and reviewers. A method could be added to do this, but it isn't strictly necessary. (say public List getStateEPeople( WorkflowItem wi, int state ) could return people affected by the item's current state.

Method Summary

static void	abort(Context c, WorkflowItem wi, EPerson e) abort() aborts a workflow, completely deleting it (administrator do this) (it will basically do a reject from any state - the item ends up back in the user's PersonalWorkspace
static void	advance(Context c, WorkflowItem wi, EPerson e) approveAction() sends an item forward in the workflow (reviewers, approvers, and editors all do an 'approve' to move the item forward) if the item arrives at the submit state, then remove the WorkflowItem and call the archive() method to put it in the archive, and email notify the submitter of a successful submission
static void	claim(Context c, WorkflowItem wi, EPerson e) claim() claims a workflow task for an EPerson
static String	getItemTitle(WorkflowItem wi) get the title of the item in this workflow
static List	getOwnedTasks(Context c, EPerson e) getOwnedTasks() returns a List of WorkflowItems containing the tasks claimed and owned by an EPerson.
static List	getPooledTasks(Context c, EPerson e) getPooledTasks() returns a List of WorkflowItems an EPerson could claim (as a reviewer, etc.) for display on a user's MyDSpace page.
static String	getSubmitterName(WorkflowItem wi) get the name of the eperson who started this workflow
static int	getWorkflowID(String state) Translate symbolic name of workflow state into number.
static WorkspaceItem	reject(Context c, WorkflowItem wi, EPerson e, String rejection_message) rejects an item - rejection means undoing a submit - WorkspaceItem is created, and the WorkflowItem is removed, user is emailed rejection_message.
static WorkflowItem	start(Context c, WorkspaceItem wsi) startWorkflow() begins a workflow - in a single transaction do away with the PersonalWorkspace entry and turn it into a WorkflowItem.
static WorkflowItem	startWithoutNotify(Context c, WorkspaceItem wsi) startWithoutNotify() starts the workflow normally, but disables notifications (useful for large imports,) for the first workflow step - subsequent notifications happen normally
static void	unclaim(Context c, WorkflowItem wi, EPerson e) unclaim() returns an owned task/item to the pool
