Here's my case:

I have 2 Streams (A and B) and a workspace (W) that targets on Stram A.
Once a week i accept all pending changes on W and switch flow target from A to B.
All accepted changesets now become outgoing changeSets and that's ok.

With this situation, i need to analyze all chageSets gathering information about which workItem are associated to each changeSet, when it has been delivered and for each file in a changeset, i need to know name, path and if it's new or only modified.

My first approach was to manualy select all outgoing changeSets in the treeViewer displayed in Pending change view and cycle on it.
Now i know that this is not a good solution, but at that moment was the shorter and faster way.

Here the code:

private void retrieveChangeSets() {
    changeSetList.clear();
    ISelection selection = viewer.getSelection();
    if (selection instanceof IStructuredSelection) {
        findChangeSet(((IStructuredSelection) selection).toList());
    }
}
@SuppressWarnings("unchecked")
private void findChangeSet(List<Object> list) {
    for (Object o : list) {
        if (o instanceof IRemoteActivity)
            addChangeSet((IRemoteActivity) o);
        if (o instanceof IRemoteChangeSummary)
            addChangeSet(((IRemoteChangeSummary) o).getActivity());
        if (o instanceof IFileSystemWorkItem)
            addChangeSet(((IFileSystemWorkItem) o).getActivity());
        if (o instanceof IActivityFolder)
            addChangeSet(((IActivityFolder) o).getActivity());
        if (o instanceof IActivitySource) {
            findChangeSet(((IActivitySource) o).getActivities());
            findChangeSet(((IActivitySource) o).getBaselines());
        }
        if (o instanceof IMultiComponentSyncContext) {
            viewer.expandToLevel(o, 1);
            IComponentSyncContext[] components = ((IMultiComponentSyncContext) o).getComponentSyncContexts();
            for (IComponentSyncContext c : components) {
                viewer.expandToLevel(c, 1);
                findChangeSet(c.getActivitySources());
            }
        }
        if (o instanceof IComponentSyncContext) {
            viewer.expandToLevel(o, 1);
            findChangeSet(((IComponentSyncContext) o).getActivitySources());
        }
        if (o instanceof IBaselineGroup) {
            viewer.expandToLevel(o, 1);
            IBaselineGroup base = ((IBaselineGroup) o);
            ComponentSyncContext context = ((ComponentSyncContext) base.getActivitySource().getModel());
            while (context.getEventManager().internalIsBusy()) {
                Display.getDefault().readAndDispatch();
            }
            findChangeSet(((IBaselineGroup) o).getActivities());
        }
    }
}
@SuppressWarnings("unchecked")
private void addChangeSet(IRemoteActivity activity) {
    if (activity instanceof ChangeSetNode) {
        ChangeSetNode changeNode = (ChangeSetNode) activity;
        chgSet = new ChangeSetModel();
        changeSetList.add(chgSet);
        for (IFileSystemWorkItem wi : changeNode.getWorkItems()) {
            chgSet.addWorkItem(getWorkItemDetail(wi));
        }
        List<IRemoteChangeSummary> changelist = changeNode.getChanges();
        for (IRemoteChangeSummary changeSummary : changelist) {
            chgSet.addChangeSummary(changeSummary);
        }
    }
}

Reanding around the forum and documentation, now I'm contemplating the chance to convert this manual work with a scheduled procedure but I'm basically not sure if it's doable and where to start.


EDIT1: i dont know how to highlight my java code quote
EDIT2: highlighted

Finally i found out how to know if a resource is being added:

private void addChangeSet(IRemoteActivity activity) {
    if (activity instanceof ChangeSetNode) {
        ChangeSetNode changeNode = (ChangeSetNode) activity;
        chgSet = new ChangeSetModel();
        changeSetList.add(chgSet);
        for (IFileSystemWorkItem wi : changeNode.getWorkItems()) {
            chgSet.addWorkItem(getWorkItemDetail(wi));
        }
        List<iremotechangesummary> changelist = changeNode.getChanges();
        for (IRemoteChangeSummary changeSummary : changelist) {
            IChangeSummary summary = changeSummary.getChangeSummary();
            if (summary.isChangeType(IChangeSummary.ADD))
                System.out.println("new Resource: "+changeSummary.getAfterPath());
            chgSet.addChangeSummary(changeSummary);
        }
    }
}
