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.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!--
