Selecting Children

• Select which child to render by its child index

• Special values:

  • Render no children: CHILD_NONE

  • Render all children: CHILD_ALL

• Or select a set of children with a bit mask

  • A value of CHILD_MASK enables mask use

  • Set a member of a Java BitSet for each child to render

These values, when used in place of a nonnegative integer index value, indicate which children of the Switch node are selected for rendering. A value of CHILD_NONE indicates that no children are rendered. A value of CHILD_ALL indicates that all children are rendered, effectively making this Switch node operate as an ordinary Group node. A value of CHILD_MASK indicates that the childMask BitSet is used to select the children that are rendered.

public class BitSet
extends Object
implements Cloneable, Serializable
This class implements a vector of bits that grows as needed. Each component of the bit set has a boolean value. The bits of a BitSet are indexed by nonnegative integers. Individual indexed bits can be examined, set, or cleared. One BitSet may be used to modify the contents of another BitSet through logical AND, logical inclusive OR, and logical exclusive OR operations.
By default, all bits in the set initially have the value false.
