Table / Select iterators

[Jani Laakso]

Consider adding similar functionality as below at least for Table component. Useful e.g. when user deletes single row from a table, UI should select next "available" row automatically.

This is used in Testing Toolkit.

/**
     * Get previous table item id
     * 
     * @param table
     * @param id
     * @return
     */
    @SuppressWarnings("unchecked")
    public static Object getPrevTableItemId(Table table, Object id) {
        Object prevId = null;
        for (Iterator it = table.getItemIds().iterator(); it.hasNext();) {
            Object itemId = it.next();
            if (itemId.equals(id)) {
                return prevId;
            }
            prevId = itemId;
        }
        return null;
    }

    /**
     * Get next table item id
     * 
     * @param table
     * @param itemId
     * @return
     */
    @SuppressWarnings("unchecked")
    public static Object getNextTableItemId(Table table, Object itemId) {
        Iterator it = table.getItemIds().iterator();
        for (; it.hasNext();) {
            Object nextItemId = it.next();
            if (nextItemId.equals(itemId)) {
                break;
            }
        }
        return (it.hasNext() ? it.next() : null);
    }

    /**
     * Get next table item id, if next null then return first item.
     * 
     * @param table
     * @param itemId
     * @return
     */
    public static Object getNextTableItemIdWrapped(Table table, Object itemId) {
        Object nextItemId = getNextTableItemId(table, itemId);

        if (nextItemId != null)
            return nextItemId;
        else {
            // wrapped
            nextItemId = table.firstItemId();
            // return null if table has only one item
            if (itemId.equals(nextItemId))
                return null;
            else
                return nextItemId;
        }
    }

Testing Tools Server uses these, check code from there..
