Detailed Description

Switch node instances.

Constructor & Destructor Documentation

Switch (  const NodeType &    nodeType, const ScopePtr &    scope )

Constructor. Parameters: nodeType  the NodeType associated with the node instance. scope  the Scope to which the node belongs.

~Switch (    )  throw () [virtual]

Destructor.

Member Function Documentation

const BVolume * getBVolume (    )  const [virtual]

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

bool isModified (    )  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 Node.

void processSet_choice (  const FieldValue &    mfnode, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

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

void processSet_whichChoice (  const FieldValue &    sfint32, double    timestamp )  throw (std::bad_cast) [private]

set_whichChoice eventIn handler. Parameters: sfint32  an SFInt32 value. timestamp  the current time. Exceptions: std::bad_cast  if sfint32 is not an SFInt32. std::bad_alloc  if memory allocation fails.

void recalcBSphere (    )  [private, virtual]

Recalculate the bounding volume.

void render (  Viewer &    viewer, VrmlRenderContext    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 Node.

void updateModified (  NodePath &    path, int    flags = 0x003 )  [virtual]

Propagate the bvolume dirty flag from children to parents. Parameters: path  stack of ancestor nodes. flags  1 indicates normal modified flag, 2 indicates the bvolume dirty flag, 3 indicates both. Reimplemented from Node.
