Detailed Description

Abstract base class for grouping nodes.

Constructor & Destructor Documentation

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:
[in] type the node_type associated with the node.
[in] scope the scope the node belongs to.


Member Function Documentation

const std::vector< boost::intrusive_ptr< openvrml::node > > openvrml::grouping_node::children (  )  const throw ( std::bad_alloc )

Get the children in the scene graph.

This function delegates to do_children.

Returns:
the children in the scene graph.
Exceptions:
std::bad_alloc if memory allocation fails.

void openvrml::grouping_node::activate_pointing_device_sensors ( double  timestamp,
bool  over,
bool  active,
const double(&)  p[3] 
)

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

Delegates to do_activate.

Parameters:
[in] timestamp the current time.
[in] over whether the pointer is over sensitive geometry.
[in] active whether the pointer has activated sensitive geometry.
[in] p the activation point.

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

Cast to a grouping_node.

Returns:
a pointer to this grouping_node.

Reimplemented from openvrml::node.

const std::vector< boost::intrusive_ptr< openvrml::node > > openvrml::grouping_node::do_children (  )  const throw ( std::bad_alloc ) [private, pure virtual]

Get the children in the scene graph.

Returns:
the child nodes in the scene graph.
Exceptions:
std::bad_alloc if memory allocation fails.
