Returns a list of fields, including the eventIn's and eventOut's.

(Inherited from SoFieldContainer.)
Public methodGetAlternateRep

This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type).

Remarks

This node represents a subgraph that was read from a named input file. When an OIV.Inventor.Nodes.SoFile node is written out, just the field containing the name of the file is written; no children are written out. When an OIV.Inventor.Nodes.SoFile is encountered during reading, reading continues from the named file, and all nodes read from the file are added as hidden children of the file node.

Whenever the OIV.Inventor.Nodes.SoFile.name field changes, any existing children are removed and the contents of the new file is read in. The file node remembers what directory the last file was read from and will read the new file from the same directory after checking the standard list of directories (see OIV.Inventor.SoInput), assuming the field isn't set to an absolute path name.

The children of an OIV.Inventor.Nodes.SoFile node are hidden; there is no way of accessing or editing them. If you wish to edit the contents of an OIV.Inventor.Nodes.SoFile node, you can modify the contents of the named file and then "touch" the OIV.Inventor.Nodes.SoFile.name field (see OIV.Inventor.Fields.SoField). Alternatively, you can use the OIV.Inventor.Nodes.SoFile.CopyChildren() method to get an editable copy of the file node's children. Note that this does not affect the original file on disk, however.

FILE FORMAT/DEFAULT

File {
name "<Undefined file>"
}

ACTION BEHAVIOR

OIV.Inventor.Actions.SoGLRenderAction, OIV.Inventor.Actions.SoCallbackAction, OIV.Inventor.Actions.SoGetBoundingBoxAction, OIV.Inventor.Actions.SoGetMatrixAction, OIV.Inventor.Actions.SoHandleEventAction Traverses its children just as OIV.Inventor.Nodes.SoGroup does.

OIV.Inventor.Actions.SoRayPickAction Traverses its hidden children, but, if intersections are found, generates paths that end at the OIV.Inventor.Nodes.SoFile node.

OIV.Inventor.Actions.SoWriteAction Writes just the OIV.Inventor.Nodes.SoFile.name field and no children.
