In addition to the list of children - * inherited from the base Group class, OrderedGroup defines an - * integer array of child indices that specify the order in which its - * children are rendered. This provides a level of indirection in - * determining the rendering order of its children. By default, the - * child index order array is null, and the children are rendered in - * increasing index order. - * - * <p> - * When the child index order array is non-null, it must be the same - * length as the number of children. Every entry in the array must - * have a unique value between 0 and <code>numChildren-1</code> (i.e., - * there must be no duplicate values and no missing indices). The - * order that the child indices appear in the child index order array - * determines the order in which the children are rendered. The child - * at <code>childIndexOrder[0]</code> is rendered first, followed by - * <code>childIndexOrder[1]</code>, and so on, with the child at - * <code>childIndexOrder[numChildren-1]</code> rendered - * last. - * - * <p> - * The child index order array only affects rendering. List - * operations that refer to a child by index, such as getChild(index), - * will not be altered by the entries in this array. They will get, - * enumerate, add, remove, etc., the children based on the actual - * index in the group node. However, some of the list operations, - * such as addChild, removeChild, etc., will update the child index - * order array as a result of their operation. For example, - * removeChild will remove the entry in the child index order array - * corresponding to the removed child's index and adjust the remaining - * entries accordingly. See the documentation for these methods for - * more details. - */ - -public class OrderedGroup extends Group { - - private boolean checkArr[] = null; - - /** - * Specifies that this OrderedGroup node - * allows reading its child index order information. - * - * @since Java 3D 1.3 - */ - public static final int ALLOW_CHILD_INDEX_ORDER_READ = - CapabilityBits.ORDERED_GROUP_ALLOW_CHILD_INDEX_ORDER_READ; - - /** - * Specifies that this OrderedGroup node - * allows writing its child index order information. - * - * @since Java 3D 1.3 - */ - public static final int ALLOW_CHILD_INDEX_ORDER_WRITE = - CapabilityBits.ORDERED_GROUP_ALLOW_CHILD_INDEX_ORDER_WRITE; - - // Array for setting default read capabilities - private static final int[] readCapabilities = { - ALLOW_CHILD_INDEX_ORDER_READ - }; - - /** - * Constructs and initializes a new OrderedGroup node object. - * The childIndexOrder array is initialized to null, meaning - * that its children are rendered in increasing index order. - */ - public OrderedGroup() { - // set default read capabilities - setDefaultReadCapabilities(readCapabilities); - } - - - /** - * Sets the childIndexOrder array.
