SoUnknownNode()
Constructor.
virtual void write(SoWriteAction *action)
virtual bool readInstance(SoInput *in, unsigned short flags)
Reads field type information, fields, and children.
void setClassName(const char *name)
static void initClass()
virtual const char * getFileFormatName() const
Returns file format name.
virtual void search(SoSearchAction *action)
Override search so we don't search alternateRep.
virtual SoNode * addToCopyDict() const
Recursively adds this node and all nodes under it to the copy dictionary.
virtual void copyContents(const SoFieldContainer *fromFC, bool copyConnections)
Copies the contents of the given node into this instance.
Writes a scene graph to a file.
