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.
SoType SoMFNode::getClassTypeId | ( | void | ) | [static] |
Returns a unique type identifier for this field class.
Reimplemented from SoMField.
SoType SoMFNode::getTypeId | ( | void | ) | const [virtual] |
Returns the type identification instance which uniquely identifies the Coin field class the object belongs to.
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. \
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.
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.
SoNode * SoMFNode::getNode | ( | int | idx | ) | const |
Returns 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.
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.
int SoMFNode::getNumNodes | ( | void | ) | const |
Returns 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.
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.
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.
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.
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.
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.
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.
