virtual const std::vector < node_ptr > &	children () const =0 throw ()
	Get the children in the scene graph.
virtual void	activate (double timestamp, bool over, bool active, double *p)=0
	Called in response to user interaction to activate any child pointing device sensor nodes.
Protected Member Functions
	grouping_node (const node_type &type, const boost::shared_ptr< openvrml::scope > &scope) throw ()
	Construct.
Private Member Functions
virtual grouping_node *	to_grouping () throw ()
	Cast to a grouping_node.

openvrml::grouping_node::~grouping_node ( ) throw () [pure virtual]

Destroy.

openvrml::grouping_node::grouping_node	(	const node_type &	type,
		const boost::shared_ptr< openvrml::scope > &	scope
	)			throw () `[protected]`

Construct.

Parameters:

	type	the node_type associated with the node.
	scope	the Scope the node belongs to.

const std::vector< node_ptr > & openvrml::grouping_node::children ( ) const throw () [pure virtual]

Get the children in the scene graph.

void openvrml::grouping_node::activate	(	double	timestamp,
		bool	over,
		bool	active,
		double *	p
	)			`[pure virtual]`

Called in response to user interaction to activate any child pointing device sensor nodes.

Parameters:

	timestamp	the current time.
	over	whether the pointer is over sensitive geometry.
	active	whether the pointer has activated sensitive geometry.
	p	the activation point.

grouping_node * openvrml::grouping_node::to_grouping ( ) throw () [private, virtual]
