The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:
Switch { exposedField MFNode choice [] exposedField SFInt32 whichChoice -1 # [-1, inf) }
The Switch grouping node traverses zero or one of the nodes specified in the choice field. 4.6.5, Grouping and children nodes (<http://www.web3d.org/technicalinfo/specifications/vrml97/part1/concepts.html#4.6.5>), describes details on the types of nodes that are legal values for choice.
The whichChoice field specifies the index of the child to traverse, with the first child having index 0. If whichChoice is less than zero or greater than the number of nodes in the choice field, nothing is chosen. All nodes under a Switch continue to receive and send events regardless of the value of whichChoice. For example, if an active SoVRMLTimeSensor is contained within an inactive choice of an Switch, the SoVRMLTimeSensor sends events regardless of the Switch's state.

Constructor. choices is the expected number of children. |

Destructor. |
|
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoGroup. |
|

If it returns
The default method returns Reimplemented from SoNode. |
|
|
Inserts choice at index idx. |
|
Returns the choice at index idx. |
|
Finds the index for choice, or -1 if not found. |
|
Returns the number of choices. |
|
Removes the choice at index idx. |
|
If choice is found, remove it. |
|
Removes all choices. |

Replace the choice at index idx with choice. |
|
Find old, and replace it with choice. |
|
This function performs the typical operation of a node for any action. Reimplemented from SoGroup. |
|
Action method for SoCallbackAction. Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph. Reimplemented from SoGroup. |
|
Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoGroup. |
|
Action method for SoPickAction. Does common processing for SoPickAction action instances. Reimplemented from SoGroup. |
|
Action method for the SoGetBoundingBoxAction. Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node. Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables. Reimplemented from SoGroup. |
|
Action method for SoHandleEventAction. Inspects the event data from action, and processes it if it is something which this node should react to. Nodes influencing relevant state variables for how event handling is done also overrides this method. Reimplemented from SoGroup. |
|
Action method for SoGetMatrixAction. Updates action by accumulating with the transformation matrix of this node (if any). Reimplemented from SoGroup. |
|
Action method for SoSearchAction. Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the search is not deemed successful for the node.
Reimplemented from SoGroup. |
|
Action method for SoWriteAction. Writes out a node object, and any connected nodes, engines etc, if necessary. Reimplemented from SoGroup. |
|
Action method for SoAudioRenderAction. Does common processing for SoAudioRenderAction action instances. Reimplemented from SoGroup. |
|
Append a child node to the list of children nodes this group node is managing. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Insert a child node at position newchildindex. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Returns pointer to child node at index. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Returns index in our list of children for child node, or -1 if node is not a child of this group node. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Returns number of child nodes managed by this group. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Remove node at childindex in our list of children. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Remove child from the set of children managed by this group node. Will decrease the reference count of child by 1. This is a convenience method. It will simply call findChild() with child as argument, and then call removeChild(int) if the child is found. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Do not manage the children anymore. Will dereference all children by 1 as they are removed. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Replace child at index with newChild. Dereferences the child previously at index, and increases the reference count of newChild by 1. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Replace oldchild with newchild. Dereferences oldchild by 1, and increases the reference count of newchild by 1. This is a convenience method. It will simply call findChild() with oldchild as argument, and call replaceChild(int, SoNode*) if the child is found. Please note that this method is not virtual in the original SGI Inventor API. Reimplemented from SoGroup. |
|
Returns list of children. Reimplemented from SoGroup. |
|
Notifies all auditors for this instance when changes are made. Reimplemented from SoNode. |
|
This method is mainly intended for internal use during file import operations. It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.
flags is used internally during binary import when reading user extension nodes, group nodes or engines. Reimplemented from SoGroup. |
|
Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is This is the method that should be overridden by subclasses which needs to account for internal data that are not handled automatically. Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to it's parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:
void MyCoinExtensionNode::copyContents(const SoFieldContainer * from, SbBool copyconnections) { // let parent superclasses do their thing (copy fields, copy // instance name, etc etc) SoNode::copyContents(from, copyconnections); // [..then copy internal data..] } Reimplemented from SoGroup. |

Contains the children. |
|
Selected choice. Can be a positive number from 0 to <num children-1>, or one of the constants SO_SWITCH_NODE, SO_SWITCH_ALL or SO_SWITCH_INHERIT. Default value is SO_SWITCH_NONE. |
