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.
static SoType SoMFNode::getClassTypeId | ( | void | ) | [static] |
Returns a unique type identifier for this field class.
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.
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. \
Referenced by findNode(), and getNode().
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.
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.

void SoMFNode::addNode | ( | SoNode * | node | ) |
Adds a node at the end of the array.

int | idx | ||

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.

virtual void SoMFNode::insertSpace | ( | int | start, |
int | numarg | ||
) | [virtual] |
