Bug 90257 [Preferences] Want to create an instanceof of a WorkingCopyManager
20050405 I'm currently referencing the internal class org.eclipse.ui.internal.preferences.WorkingCopyManager I have a base class that manages all the current settings and I changes that class to use the working copy manager. For the following reasons I also have to function when I don't get a working copy manager. To avoid complicated code it would be nice if in these case I could just use an internal instance of the working copy manager. - In the preference page, when testing if my container is really of kind IWorkbenchPreferenceContainer (so I can access the working copy manager) I have to also handle the case that the test returns false - We have some pages that are contributed by extension point that don't give me access to the container due to API limitations.

	private void testIfOptionsComplete(Key[] allKeys) {
		for (int i= 0; i < allKeys.length; i++) {
			if (allKeys[i].getStoredValue(fLookupOrder, false, fManager) == null) {
				JavaPlugin.logErrorMessage("preference option missing: " + allKeys[i] + " (" + this.getClass().getName() +')');  
			}
		}
	}
	
	private int getRebuildCount() {
		return fManager.getWorkingCopy(new DefaultScope().getNode(JavaUI.ID_PLUGIN)).getInt(REBUILD_COUNT_KEY, 0);
	}

		fRebuildCount++;
		fManager.getWorkingCopy(new DefaultScope().getNode(JavaUI.ID_PLUGIN)).putInt(REBUILD_COUNT_KEY, fRebuildCount);
