osg::Group::Group | ( | ) |
Copy constructor using CopyOp to manage deep vs shallow copy.
virtual osg::Group::~Group | ( | ) | [protected, virtual] |
virtual bool osg::Group::addChild | ( | Node * | child | ) | [virtual] |
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.
Reimplemented in osg::LOD, osg::PagedLOD, osg::ProxyNode, osg::Switch, and osgSim::MultiSwitch.

virtual Group* osg::Group::asGroup | ( | ) | [inline, virtual] |

virtual void osg::Group::childRemoved | ( | unsigned | int, | |
unsigned | int | |||
) | [inline, protected, virtual] |
virtual BoundingSphere osg::Group::computeBound | ( | ) | const [virtual] |
Compute the bounding sphere around Node's geometry or children. This method is automatically called by getBound() when the bounding sphere has been marked dirty via dirtyBound().
Reimplemented from osg::Node.
Reimplemented in osg::AutoTransform, osg::ClipNode, osg::LightSource, osg::LOD, osg::OccluderNode, osg::ProxyNode, osg::Switch, osg::Transform, and osgSim::Impostor.
bool osg::Group::containsNode | ( | const Node * | node | ) | const [inline] |
Return true if node is contained within Group.
const Node* osg::Group::getChild | ( | unsigned int | i | ) | const [inline] |
Return child node at position i.
Node* osg::Group::getChild | ( | unsigned int | i | ) | [inline] |
Return child node at position i.
unsigned int osg::Group::getChildIndex | ( | const Node * | node | ) | const [inline] |
Get the index number of child, return a value between 0 and _children.size()-1 if found, if not found then return _children.size().
unsigned int osg::Group::getNumChildren | ( | ) | const [inline] |
Return the number of chilren nodes.
virtual bool osg::Group::insertChild | ( | unsigned int | index, | |
Node * | child | |||
) | [virtual] |
Insert Node to Group at specific location. The new child node is inserted into the child list before the node at the specified index. No nodes are removed from the group with this operation.
Reimplemented in osg::Switch, and osgSim::MultiSwitch.
osg::Group::META_Node | ( | osg | , | |
Group | ||||
) |
virtual void osg::Group::releaseGLObjects | ( | osg::State * | = 0 |
) | const [virtual] |
If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objexts for all graphics contexts.
Reimplemented from osg::Node.
Reimplemented in osg::CameraNode.
bool osg::Group::removeChild | ( | unsigned int | pos, | |
unsigned int | numChildrenToRemove = 1 | |||
) | [inline] |
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. Note, do not override, only override removeChildren(,) is required.
bool osg::Group::removeChild | ( | Node * | child | ) | [inline] |
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. Note, do not override, only override removeChildren(,) is required.
Reimplemented in osgSim::MultiSwitch.
virtual bool osg::Group::removeChildren | ( | unsigned int | pos, | |
unsigned int | numChildrenToRemove | |||
) | [virtual] |
Remove children from Group. Note, must be override by subclasses of Group which add per child attributes.
Reimplemented in osg::LOD, osg::PagedLOD, osg::ProxyNode, and osg::Switch.
virtual bool osg::Group::setChild | ( | unsigned int | i, | |
Node * | node | |||
) | [virtual] |
Set child node at position i. Return true if set correctly, false on failure (if node==NULL || i is out of range). When Set can be successful applied, the algorithm is : decrement the reference count origNode and increment the reference count of newNode, and dirty the bounding sphere to force it to recompute on next getBound() and return 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.
virtual void osg::Group::traverse | ( | NodeVisitor & | nv | ) | [virtual] |
Traverse downwards : calls children's accept method with NodeVisitor.
Reimplemented from osg::Node.
Reimplemented in osg::LOD, osg::PagedLOD, osg::ProxyNode, osg::Sequence, osg::Switch, osgFX::Effect, osgSim::DOFTransform, osgSim::Impostor, osgSim::MultiSwitch, osgSim::OverlayNode, osgSim::VisibilityGroup, and osgTerrain::HeightFieldNode.
