This static method returns the \fBSoType\fP object associated with objects of this class\&. 
.SS "\fBSoType\fP SoVRMLParent::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\&. 
.PP
Reimplemented from \fBSoGroup\fP\&.
.PP
Reimplemented in \fBSoVRMLAnchor\fP, \fBSoVRMLBillboard\fP, \fBSoVRMLCollision\fP, \fBSoVRMLGroup\fP, and \fBSoVRMLTransform\fP\&.
.SS "const \fBSoFieldData\fP ** SoVRMLParent::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

 Returns the \fBSoFieldData\fP class which holds information about fields in this node\&. 
.SS "const \fBSoFieldData\fP * SoVRMLParent::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 \fBSoGroup\fP\&.
.PP
Reimplemented in \fBSoVRMLAnchor\fP, \fBSoVRMLBillboard\fP, \fBSoVRMLCollision\fP, \fBSoVRMLGroup\fP, and \fBSoVRMLTransform\fP\&.
.SS "void SoVRMLParent::initClass (void )\fR [static]\fP"

.SS "SbBool SoVRMLParent::affectsState (void ) const\fR [virtual]\fP"
Returns \fRTRUE\fP if the node could have any effect on the state during traversal\&.

.PP
If it returns \fRFALSE\fP, no data in the traversal state will change from the pre-traversal state to the post-traversal state\&. The \fBSoSeparator\fP node will for instance return \fRFALSE\fP, as it pushes and pops the state before and after traversal of its children\&. All \fBSoShape\fP nodes will also return \fRFALSE\fP, as just pushing out geometry data to the rendering engine won't affect the actual rendering state\&.

.PP
The default method returns \fRTRUE\fP, on a "better safe than sorry" philosophy\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoVRMLParent::addChild (\fBSoNode\fP * node)\fR [virtual]\fP"
Append a child \fInode\fP to the list of children nodes this group node is managing\&.

.PP
Please note that this method is not virtual in the original SGI Inventor API\&.

.SS "SbBool SoVRMLParent::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 \fBSoGroup\fP\&.
.SS "void SoVRMLParent::copyContents (const \fBSoFieldContainer\fP * from, SbBool copyconnections)\fR [protected]\fP, \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\&.\&.]
}
