## 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.
MFString | url
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.
SFVec3f | bboxCenter
SFVec3f | bboxSize

## Detailed Description

Here is the documentation for this node type, from the ISO standard.

## 6.36 Inline

The Inline node is a grouping node that reads its children data from a location in the World Wide Web. Exactly when its children are read and displayed is not defined (e.g. reading the children may be delayed until the Inline node's bounding box is visible to the viewer). The url field specifies the URL containing the children. An Inline node with an empty URL does nothing.

Each specified URL shall refer to a valid VRML file that contains a list of children nodes, prototypes, and routes at the top level as described in 4.6.5, Grouping and children nodes. The results are undefined if the URL refers to a file that is not VRML or if the VRML file contains non-children nodes at the top level.

If multiple URLs are specified, the browser may display a URL of a lower preference VRML file while it is obtaining, or if it is unable to obtain, the higher preference VRML file. Details on the url field and preference order can be found in 4.5, VRML and the World Wide Web.

The results are undefined if the contents of the URL change after it has been loaded.

The bboxCenter and bboxSize fields specify a bounding box that encloses the Inline 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 shall be calculated by the browser. A description of the bboxCenter and bboxSize fields is in 4.6.4, Bounding boxes.

## Constructor & Destructor Documentation

Inline | ( | 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);

~Inline | ( |  | ) | `[virtual]`

Virtual destructor, does nothing

## Member Function Documentation

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:

- url
- bboxCenter
- bboxSize

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:

- 0 : url
- 1 : bboxCenter
- 2 : bboxSize This function is useful, with nbFields() if you want to traverse all fields of a Node.

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:

- set_url

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. emarks This class has no eventIn. 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:

- url_changed

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:

- 0 : url_changed This function is useful, with nbEventsOut() if you want to traverse all events in of a Node.

Implements Node.

const char * typeName | ( |  | ) | const`[inline, virtual]`

Returns `"Inline"`. 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.

virtual Node* duplicate | ( | std::map< const Node *, Node * > & |  | ) | const`[virtual]`

Implements Node.
