Constructor & Destructor Documentation

openvrml::vrml97_node::switch_node::switch_node (  const node_type &  type, const scope_ptr &  scope )

Construct. Parameters: type  the node_type associated with the node instance. scope  the scope to which the node belongs.

Member Function Documentation

void openvrml::vrml97_node::switch_node::activate (  double  time, bool  isOver, bool  isActive, double *  p )  [virtual]

Pass on to enabled touchsensor child. Implements openvrml::grouping_node.

const bounding_volume & openvrml::vrml97_node::switch_node::bounding_volume (   )  const [virtual]

Get the bounding volume. Returns: the bounding volume associated with the node. Reimplemented from openvrml::node.

const std::vector< node_ptr > & openvrml::vrml97_node::switch_node::children (   )  const throw () [virtual]

Get the children in the scene graph. Returns: the child nodes in the scene graph. Implements openvrml::grouping_node.

bool openvrml::vrml97_node::switch_node::modified (   )  const [virtual]

Determine whether the node has been modified. Returns: true if the node or one of its children has been modified, false otherwise. Reimplemented from openvrml::node.

void openvrml::vrml97_node::switch_node::process_set_choice (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_choice eventIn handler. Parameters: value  an mfnode value. timestamp  the current time. Exceptions: std::bad_cast  if value is not an mfnode. std::bad_alloc  if memory allocation fails.

void openvrml::vrml97_node::switch_node::process_set_whichChoice (  const field_value &  value, double  timestamp )  throw (std::bad_cast) [private]

set_whichChoice eventIn handler. Parameters: value  an sfint32 value. timestamp  the current time. Exceptions: std::bad_cast  if value is not an sfint32.

void openvrml::vrml97_node::switch_node::render (  openvrml::viewer &  viewer, rendering_context  context )  [virtual]

Render the node. The child corresponding to whichChoice is rendered. Nothing is rendered if whichChoice is -1. Parameters: viewer  a Viewer. context  a rendering context. Reimplemented from openvrml::node.
