.SH "Detailed Description"
.PP 
The \fBSoFile\fP class is node container for another model file\&. 

This node provides a way to split your models into a set of 'component' models to include into larger 'master' files\&.

.PP
Just provide the name of the model file to include in the \fBSoFile::name\fP field, and it will automatically be loaded and have its nodes inserted into the scene graph at the point of the \fBSoFile\fP node\&.

.PP
You can also set the \fBSoFile::name\fP field manually\&. Such an action will then automatically trigger an invocation of a read operation which imports the filename you set in the field\&.

This static method returns the \fBSoType\fP object associated with objects of this class\&. 
.br
 
.SS "\fBSoType\fP SoFile::getTypeId (void ) const\fR [virtual]\fP"
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for runtime type checking and 'downward' casting\&. 
.br
 
.PP
Implements \fBSoBase\fP\&.
.SS "const \fBSoFieldData\fP ** SoFile::getFieldDataPtr (void )\fR [static]\fP, \fR [protected]\fP"
\fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP
.br

.br
 Returns the \fBSoFieldData\fP class which holds information about fields in this node\&. 
.br
 
.SS "const \fBSoFieldData\fP * SoFile::getFieldData (void ) const\fR [protected]\fP, \fR [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fRNULL\fP\&. 
.PP
Reimplemented from \fBSoFieldContainer\fP\&.
.SS "void SoFile::doAction (\fBSoAction\fP * action)\fR [virtual]\fP"
This function performs the typical operation of a node for any action\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::callback (\fBSoCallbackAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoCallbackAction\fP\&.

.PP
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::GLRender (\fBSoGLRenderAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGLRenderAction\fP\&.

.PP
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\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::getBoundingBox (\fBSoGetBoundingBoxAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGetBoundingBoxAction\fP\&.

.PP
Calculates bounding box and center coordinates for node and modifies the values of the \fIaction\fP to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node\&.

.PP
Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::getMatrix (\fBSoGetMatrixAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoGetMatrixAction\fP\&.

.PP
Updates \fIaction\fP by accumulating with the transformation matrix of this node (if any)\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::handleEvent (\fBSoHandleEventAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoHandleEventAction\fP\&.

.PP
Inspects the event data from \fIaction\fP, and processes it if it is something which this node should react to\&.

.PP
Nodes influencing relevant state variables for how event handling is done also override this method\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::pick (\fBSoPickAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoPickAction\fP\&.

.PP

.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::getPrimitiveCount (\fBSoGetPrimitiveCountAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGetPrimitiveCountAction\fP\&.

.PP
Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the \fIaction\fP\&.

.PP
Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::audioRender (\fBSoAudioRenderAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoAudioRenderAction\fP\&.

.PP
Does common processing for \fBSoAudioRenderAction\fP \fIaction\fP instances\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::search (\fBSoSearchAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoSearchAction\fP\&.

.PP
Compares the search criteria from the \fIaction\fP to see if this node is a match\&. Searching is done by matching up \fIall\fP criteria set up in the \fBSoSearchAction\fP -- if \fIany\fP of the requested criteria is a miss, the search is not deemed successful for the node\&.

Returns list of children for this node\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoFile::copyContents (const \fBSoFieldContainer\fP * from, SbBool copyconnections)\fR [virtual]\fP"
Makes a deep copy of all data of \fIfrom\fP into this instance, \fIexcept\fP external scene graph references if \fIcopyconnections\fP is \fRFALSE\fP\&.

.PP
This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which need to account for internal data that are not handled automatically\&.

.PP
For copying nodes from application code, you should not invoke this function directly, but rather call the \fBSoNode::copy()\fP function:

.PP
.PP
.nf
SoNode * mynewnode = templatenode\->copy();
.fi
.PP

.PP
The same also goes for engines\&.

.PP
Make sure that when you override the \fBcopyContents()\fP method in your extension class that you also make it call upwards to its parent superclass in the inheritance hierarchy, as \fBcopyContents()\fP in for instance \fBSoNode\fP and \fBSoFieldContainer\fP does important work\&. It should go something like this:

.PP
.PP
.nf
void
MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
                                  SbBool copyconnections)
{
  // let parent superclasses do their thing (copy fields, copy
  // instance name, etc\&.)
  SoNode::copyContents(from, copyconnections);

  // [\&.\&.then copy internal data\&.\&.]
}
.fi

.SS "const \fBSbString\fP & SoFile::getFullName (void ) const"
Returns the read filename, possibly including the (relative) path where the file was found\&. Returns an empty string if no file has been read\&.

.PP
This method is an extension versus the Open Inventor API\&.

.SS "void SoFile::setSearchOK (SbBool dosearch)\fR [static]\fP"
Enables/disables searching children using \fBSoSearchAction\fP\&. 
.SS "SbBool SoFile::getSearchOK ()\fR [static]\fP"
Returns whether searching children using \fBSoSearchAction\fP is enabled\&. 
.SS "SbBool SoFile::readInstance (\fBSoInput\fP * in, unsigned short flags)\fR [protected]\fP, \fR [virtual]\fP"
This method is mainly intended for internal use during file import operations\&.

.PP
It reads a definition of an instance from the input stream \fIin\fP\&. The input stream state points to the start of a serialized / persistent representation of an instance of this class type\&.

.PP
\fRTRUE\fP or \fRFALSE\fP is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not\&. The import process should be robust and handle corrupted input streams by returning \fRFALSE\fP\&.

.PP
\fIflags\fP is used internally during binary import when reading user extension nodes, group nodes or engines\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "SbBool SoFile::readNamedFile (\fBSoInput\fP * in)\fR [protected]\fP, \fR [virtual]\fP"
Read the file named in the \fBSoFile::name\fP field\&.

.PP
Used to be a private method, moved into protected space to enable subclasses to detect when the file is (re)read\&.
