This static method returns the SoType object associated with objects of this class.

Reimplemented from SoGroup.

Reimplemented in SoVRMLAnchor, SoVRMLBillboard, SoVRMLCollision, SoVRMLGroup, and SoVRMLTransform.

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

  void foo(SoNode * node)
  {
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
    }
    else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
      SoGroup * group = (SoGroup *)node;  // safe downward cast, knows the type
    }
  }

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoGroup.

Reimplemented in SoVRMLAnchor, SoVRMLBillboard, SoVRMLCollision, SoVRMLGroup, and SoVRMLTransform.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Reimplemented from SoGroup.

Reimplemented in SoVRMLAnchor, SoVRMLBillboard, SoVRMLCollision, SoVRMLGroup, and SoVRMLTransform.

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoGroup.

Reimplemented in SoVRMLAnchor, SoVRMLBillboard, SoVRMLCollision, SoVRMLGroup, and SoVRMLTransform.

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

Reimplemented from SoGroup.

Reimplemented in SoVRMLAnchor, SoVRMLBillboard, SoVRMLCollision, SoVRMLGroup, and SoVRMLTransform.

Returns TRUE if the node could have any effect on the state during traversal.

If it returns FALSE, no data in the traversal-state will change from the pre-traversal state to the post-traversal state. The SoSeparator node will for instance return FALSE, as it pushes and pops the state before and after traversal of its children. All SoShape nodes will also return FALSE, as just pushing out geometry data to the rendering engine won't affect the actual rendering state.

The default method returns TRUE, on a 'better safe than sorry' philosophy.

Reimplemented from SoNode.

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.

This function performs the typical operation of a node for any action.

Reimplemented from SoGroup.

Reimplemented in SoVRMLBillboard, SoVRMLGroup, and SoVRMLTransform.

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.

Action method for SoWriteAction.

Writes out a node object, and any connected nodes, engines etc, if necessary.

Reimplemented from SoGroup.

Reimplemented in SoVRMLGroup.

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoGroup.

Reimplemented in SoVRMLGroup, and SoVRMLTransform.

A convenience method that can be used to update cl to match the list of nodes in nodes.

A convenience method that is used to sync the nodes in cl with all nodes in SoSFNode fields in nodewithsfnode.

Notifies all auditors for this instance when changes are made.

Reimplemented from SoNode.

Reimplemented in SoVRMLBillboard, SoVRMLCollision, SoVRMLGroup, and SoVRMLTransform.

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.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE.

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 FALSE.

This is the protected method that should be overridden by extension node / engine / dragger / whatever subclasses which needs to account for internal data that are not handled automatically.

For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:

  SoNode * mynewnode = templatenode->copy();

The same also goes for engines.

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..] }
