Documentation

General group node which maintains a list of children. Children are reference counted. This allows children to be shared with memory management handled automatically via osg::Referenced.

typedef std::vector<ref_ptr<Node> > ChildList Group()

META_Node(Group)

virtual void traverse(NodeVisitor& nv)

virtual bool addChild( Node* child )

Add Node to Group. If node is not NULL and is not contained in Group then increment its reference count, add it to the child list and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. Otherwise return false. Scene nodes can't be added as child nodes.

virtual bool removeChild( Node* child )

Remove Node from Group. If Node is contained in Group then remove it from the child list, decrement its reference count, and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. If Node is not found then return false and do not change the reference count of the Node.

virtual bool replaceChild( Node* origChild, Node* newChild )

Replace specified Node with another Node. Decrement the reference count origNode and increments the reference count of newNode, and dirty the bounding sphere to force it to recompute on next getBound() and returns true. If origNode is not found then return false and do not add newNode. If newNode is NULL then return false and do not remove origNode. Also returns false if newChild is a Scene node.

inline const int getNumChildren() const

return the number of chilren nodes

inline Node* getChild( const int i )

return child node at position i

inline const Node* getChild( const int i ) const

return child node at position i

inline bool containsNode( const Node* node ) const

return true if node is contained within Group

inline ChildList::iterator findNode( const Node* node )

return the iterator postion for specified Node. return _chilren.end() if node is not contained in Group.

inline ChildList::const_iterator findNode( const Node* node ) const

return the const_iterator postion for specified Node. return _chilren.end() if node is not contained in Group.
