       This group node usually traverses only one or none  of  its  children.  It  implements  an
       operation similar to the switch statement in C. One can use this node to switch on and off
       the effects of some properties or to switch between different properties.

       The whichChild field specifies the index of the child to traverse, where the  first  child
       has index 0.

       A value of SO_SWITCH_NONE (-1, the default) means do not traverse any children. A value of
       SO_SWITCH_INHERIT (-2) allows the index to  be  inherited  from  a  previously-encountered
       SoSwitch node or from certain other nodes (such as SoArray or SoMultipleCopy) that set the
       switch value. A value of SO_SWITCH_ALL (-3) traverses  all  children,  making  the  switch
       behave exactly like a regular SoGroup.


     SoSFInt32           whichChild
          Index  of  the  child  to  traverse,  or  one  of SO_SWITCH_NONE, SO_SWITCH_INHERIT, or


          Creates a switch node with default settings.

                         SoSwitch(int nChildren)
          Constructor that takes approximate number of children.

     static SoType       getClassTypeId()
          Returns type identifier for this class.


       SoGLRenderAction,     SoCallbackAction,     SoGetBoundingBoxAction,     SoGetMatrixAction,
       SoHandleEventAction, SoRayPickAction
          Traverses the chosen child or children.

          If  the  action's  Searching-All flag is set, always traverses all children. Otherwise,
          traverses just the chosen child or children.
