Detailed DescriptionThe 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​. See also SoNode, SoSFNode

Member Function Documentation

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​.

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​.

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​.
Referenced by findNode(), SoVRMLLOD::getChildren(), SoVRMLParent::getChildren(), SoVRMLSwitch::getChildren(), and getNode()​.

void SoMFNode::fixCopy (SbBool copyconnections) [virtual]This method is internally called after SoField::copyFrom() during scene graph copies, and should do the operations necessary for fixing up the field instance after it has gotten a new value​. The default method in the SoField superclass does nothing​. The application programmer should normally not need to consider this method, unless he constructs a complex field type which contains new references to container instances (i​.e​. nodes or engines)​. Overriding this method is then necessary to update the reference pointers, as they could have been duplicated during the copy operation​. Reimplemented from SoField​. References SoBase::assertAlive(), SoNode::copy(), SoField::enableNotify(), SoFieldContainer::findCopy(), SoMField::getNum(), and SoField::valueChanged()​.

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​. References SoFieldContainer::checkCopy(), SoMField::getNum(), and SoField::referencesCopy()​.

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​.
Since Coin 2​.0 References SoMField::getNum()​. Referenced by SoVRMLLOD::addChild(), SoVRMLParent::addChild(), and SoVRMLSwitch::addChild()​.

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 References SoMField::getNum(), and insertSpace()​. Referenced by SoVRMLLOD::insertChild(), SoVRMLParent::insertChild(), and SoVRMLSwitch::insertChild()​.

SoNode * SoMFNode::getNode (int idx) constReturns the 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 References SoMField::getNum(), and getValues()​. Referenced by SoVRMLLOD::getChild(), SoVRMLParent::getChild(), and SoVRMLSwitch::getChild()​.

int SoMFNode::findNode (const SoNode * node) constReturns 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 Coin 2​.0 References SoMField::getNum(), and getValues()​. Referenced by SoVRMLLOD::findChild(), SoVRMLParent::findChild(), SoVRMLSwitch::findChild(), removeNode(), and replaceNode()​.

int SoMFNode::getNumNodes (void) constReturns the number of nodes in this field​. 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 References SoMField::getNum()​. Referenced by SoVRMLParent::getNumChildren()​.

void SoMFNode::removeNode (int idx)Removes the 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 References deleteValues(), and SoMField::getNum()​. Referenced by SoVRMLLOD::removeChild(), SoVRMLParent::removeChild(), SoVRMLSwitch::removeChild(), and removeNode()​.

void SoMFNode::removeNode (SoNode * node)Removes the first instance of node in the field​. 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 References findNode(), and removeNode()​.

void SoMFNode::removeAllNodes (void)Removes all nodes from the field​. 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 References SoMField::setNum()​. Referenced by SoVRMLLOD::removeAllChildren(), SoVRMLParent::removeAllChildren(), and SoVRMLSwitch::removeAllChildren()​.

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 References SoMField::getNum()​. Referenced by SoVRMLLOD::replaceChild(), SoVRMLParent::replaceChild(), SoVRMLSwitch::replaceChild(), and replaceNode()​.

void SoMFNode::replaceNode (SoNode * oldnode, SoNode * newnode)Replaces the first instance of oldnode 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 References findNode(), and replaceNode()​.

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​. Referenced by removeNode()​.

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​. Referenced by insertNode()​.
