## Detailed Description

The **SoVRMLInline** class is used to insert VRML files into a scene.

**The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:**\

```
Inline {
  exposedField MFString url        []
  field        SFVec3f  bboxCenter 0 0 0     # (-,)
  field        SFVec3f  bboxSize   -1 -1 -1  # (0,) or -1,-1,-1
}
```

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 (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.5). \

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 (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.4).

### SoVRMLInline::~SoVRMLInline () \[protected\], \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoVRMLInline::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### SoType SoVRMLInline::getTypeId (void ) const \[virtual\]

Implements **SoBase**.

### const SoFieldData \*\* SoVRMLInline::getFieldDataPtr (void ) \[static\], \[protected\]

*This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\

 Returns the **SoFieldData** class which holds information about fields in this node.

### const SoFieldData \* SoVRMLInline::getFieldData (void ) const \[protected\], \[virtual\]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from **SoFieldContainer**.

### void SoVRMLInline::initClass (void ) \[static\]

### void SoVRMLInline::setFullURLName (const SbString & urlref)

Sets the full (non-relative) URL name.

### const SbString & SoVRMLInline::getFullURLName (void )

Returns the full URL name.

### SoGroup \* SoVRMLInline::copyChildren (void ) const

Returns a copy of the children.

### void SoVRMLInline::requestURLData (void )

Request URL data.

### SbBool SoVRMLInline::isURLDataRequested (void ) const

Sets whether Inline nodes should be treated as a normal Inventor **SoFile** node.

### SbBool SoVRMLInline::getReadAsSoFile (void ) \[static\]

Returns whether Inline nodes are read as **SoFile** nodes.

### void SoVRMLInline::doAction (SoAction \* action) \[virtual\]

This function performs the typical operation of a node for any action.

Reimplemented from **SoNode**.

### void SoVRMLInline::callback (SoCallbackAction \* action) \[virtual\]

Action method for **SoCallbackAction**.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the **SoCallbackAction** for extracting information about the scene graph.

Reimplemented from **SoNode**.

### void SoVRMLInline::GLRender (SoGLRenderAction \* action) \[virtual\]

Action method for the **SoGLRenderAction**.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from **SoNode**.

### void SoVRMLInline::getBoundingBox (SoGetBoundingBoxAction \* action) \[virtual\]

Action method for the **SoGetBoundingBoxAction**.

Calculates bounding box and center coordinates for node and modifies the values of the *action* to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from **SoNode**.

### void SoVRMLInline::getMatrix (SoGetMatrixAction \* action) \[virtual\]

Action method for **SoGetMatrixAction**.

Updates *action* by accumulating with the transformation matrix of this node (if any).

Reimplemented from **SoNode**.

### void SoVRMLInline::handleEvent (SoHandleEventAction \* action) \[virtual\]

Action method for **SoHandleEventAction**.

Inspects the event data from *action*, and processes it if it is something which this node should react to.

Nodes influencing relevant state variables for how event handling is done also override this method.

Reimplemented from **SoNode**.

### void SoVRMLInline::search (SoSearchAction \* action) \[virtual\]

Action method for **SoSearchAction**.

Compares the search criteria from the *action* to see if this node is a match. Searching is done by matching up *all* criteria set up in the **SoSearchAction** -- if *any* of the requested criteria is a miss, the search is not deemed successful for the node.

**See also**

**SoSearchAction**

Reimplemented from **SoNode**.

### void SoVRMLInline::pick (SoPickAction \* action) \[virtual\]

Action method for **SoPickAction**.

Does common processing for **SoPickAction** *action* instances.

### void SoVRMLInline::getPrimitiveCount (SoGetPrimitiveCountAction \* action) \[virtual\]

Action method for the **SoGetPrimitiveCountAction**.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the *action*.

Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from **SoNode**.

### SoChildList \* SoVRMLInline::getChildren (void ) const \[virtual\]

Returns list of children for this node.

Reimplemented from **SoNode**.
