Public Methods

Referenced& operator = (Referenced&)

virtual Object* clone() const

virtual bool isSameKindAs(Object* obj)

virtual const char* className() const

virtual void accept(NodeVisitor& nv)

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.

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.

int getNumChildren( void )

return the number of chilren nodes

Node* getChild( int i )

return child node at position i

bool containsNode( Node* node )

return true is node is contained within Group

ChildList::iterator findNode( Node* node )

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