Detailed Description
The SoMFNode class is a container for nodes.
This field container stores an array of pointers to nodes. It takes
care of the necessary functionality for handling copy, import and
export operations.
Note that node pointers stored in field instances of this type may be
NULL pointers.

Member Function Documentation
static SoType SoMFNode::getClassTypeId (void) [static] Returns a unique
type identifier for this field class.
See also:
getTypeId(), SoType
Reimplemented from SoMField.
virtual SoType SoMFNode::getTypeId (void) const [virtual] Returns the type
identification instance which uniquely identifies the Coin field class
the object belongs to.
See also:
getClassTypeId(), SoType
Implements SoField.
virtual void SoMFNode::copyFrom (const SoField & f) [virtual] Copy value(s)
from f into this field. f must be of the same type as this field.
Implements SoField.
virtual SbBool SoMFNode::isSame (const SoField & f) const [virtual] Check
for equal type and value(s).
Implements SoField.
const SoNode* * SoMFNode::getValues (const int start) const [inline]
Returns a pointer to the values array. .SS "void SoMFNode::initClass
(void) [static]"Internal method called upon initialization of the
library (from SoDB::init()) to set up the type system.
Reimplemented from SoMField.
SbBool SoMFNode::referencesCopy (void) const [virtual] Returns TRUE if this
field has references to any containers in the scene graph which are
also duplicated during the copy operation.
Note that this method only is valid to call during copy operations.
See also the note about the relevance of the fixCopy() method for
application programmers, as it is applicable on this method aswell.
Reimplemented from SoField.
void SoMFNode::addNode (SoNode * node) Adds a node at the end of the array.
This function is an extension for Coin, and it is not available in the
original SGI Open Inventor v2.1 API.

Coin 2.0
void SoMFNode::insertNode (SoNode * node, int idx) Inserts a node at index
idx.
This function is an extension for Coin, and it is not available in the
original SGI Open Inventor v2.1 API.
Since:
Coin 2.0
SoNode * SoMFNode::getNode (int idx) const Returns the node at index idx.

int SoMFNode::findNode (const SoNode * node) const Returns the index for
the first instance of node in the field, or -1 if not found.
This function is an extension for Coin, and it is not available in the
original SGI Open Inventor v2.1 API.
Since:

int SoMFNode::getNumNodes (void) const Returns the number of nodes in this
field.

node in the field.

void SoMFNode::replaceNode (int idx, SoNode * newnode) Replaces the node at
index idx with newnode.
This function is an extension for Coin, and it is not available in the
original SGI Open Inventor v2.1 API.
Since:
Coin 2.0
void SoMFNode::replaceNode (SoNode * oldnode, SoNode * newnode) Replaces
the first instance of oldnode with newnode.

Since:

virtual void SoMFNode::deleteValues (int start, int numarg = -1) [virtual]
Remove value elements from index start up to and including index start
+ num - 1.
Elements with indices larger than the last deleted element will be
moved downwards in the value array.
If num equals -1, delete from index start and to the end of the array.
Reimplemented from SoMField.
virtual void SoMFNode::insertSpace (int start, int numarg) [virtual] Insert
num ’slots’ for new value elements from start. The elements already
present from start will be moved ’upward’ in the extended array.
Reimplemented from SoMField.
