Public Attributes | |
Exposed Fields | |
A field that is capable of receiving events via an eventIn to change its value(s), and generating events via an eventOut when its value(s) change. | |
MFNode | children |
Fields | |
A property or attribute of a node. Each node type has a fixed set of fields. Fields may contain various kinds of data and one or many values. Each field has a default value. | |

A Group node contains children nodes without introducing a new transformation. It is equivalent to a Transform node containing an identity transform.
More details on the children, addChildren, and removeChildren fields and eventIns can be found in 4.6.5, Grouping and children nodes.
The bboxCenter and bboxSize fields specify a bounding box that encloses the Group node's children. This is a hint that may be used for optimization purposes. The results are undefined if the specified bounding box is smaller than the actual bounding box of the children at any time. A default bboxSize value, (-1, -1, -1), implies that the bounding box is not specified and, if needed, is calculated by the browser. A description of the bboxCenter and bboxSize fields is contained in 4.6.4, Bounding boxes.
Group | ( | const char * | name = "" |
) |
Construct a node with all its fields set to default value, which is equivalent to the code below:
bboxCenter.setXYZ(0,0,0); bboxSize.setXYZ(-1,-1,-1);
~Group | ( | ) | [virtual] |
Virtual destructor, does nothing
unsigned int nbFields | ( | ) | const [inline, virtual] |
Returns the number of fields (exposed or not) for this node type.
Implements Node.
wrl::Node::FieldHandle field | ( | const std::string & | n | ) | [virtual] |
Return a handle on the field named n
of the node or a "unknown" typed handle if there is no such field. Valid names are:
Implements Node.
wrl::Node::FieldHandle field | ( | unsigned int | n | ) | [virtual] |
Return a handle on the i
th field of the node or a "unknown" typed handle if there is no such node. Here is how i
is related to fields:
Implements Node.
bool isSetToDefaultValue | ( | unsigned int | i | ) | const [virtual] |
Implements Node.
unsigned int nbEventsIn | ( | ) | const [inline, virtual] |
Returns the number of events in for this node type.
Implements Node.
wrl::Node::EventInHandle eventIn | ( | const std::string & | n | ) | [virtual] |
Return a handle on the event in named n
of the node or a "unknown" typed handle if there is no such event. Valid names are:
Implements Node.
wrl::Node::EventInHandle eventIn | ( | unsigned int | n | ) | [virtual] |
Return a handle on the i
th event in of the node or a "unknown" typed handle if there is no such node. Here is how i
is related to fields:
This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.
Implements Node.
unsigned int nbEventsOut | ( | ) | const [inline, virtual] |
Returns the number of events out for this node type.
Implements Node.
wrl::Node::EventOutHandle eventOut | ( | const std::string & | n | ) | [virtual] |
Return a handle on the event out named n
of the node or a "unknown" typed handle if there is no such event. Valid names are:
Implements Node.
wrl::Node::EventOutHandle eventOut | ( | unsigned int | n | ) | [virtual] |
Return a handle on the i
th event out of the node or a "unknown" typed handle if there is no such node. Here is how i
is related to fields:
Implements Node.
const char * typeName | ( | ) | const [inline, virtual] |
Returns "Group"
. Useful for printing.
Implements Node.
wrl::Node * duplicate | ( | ) | const [virtual] |
Returns a deep copy of this node, that is a fully independant node with all children (if any) also copied. This is mainly useful for instanciating protos.
Implements Node.
