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.

See also: SoNode, SoSFNode

Member Function Documentation

◆ addNode()

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

◆ copyFrom()

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.

◆ copyValue()

virtual void SoMFNode::copyValue	(	int	to,
		int	from )

protectedvirtual

Implements SoMField.

◆ createInstance()

void * SoMFNode::createInstance ( void )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Creates a new instance of the class type corresponding to the SoType object.

◆ deleteAllValues()

virtual void SoMFNode::deleteAllValues ( void )

protectedvirtual

Implements SoMField.

◆ deleteValues()

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.

◆ findNode()

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: Coin 2.0

◆ fixCopy()

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.

◆ getClassTypeId()

SoType SoMFNode::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

◆ getNode()

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.

Since: Coin 2.0

◆ getNumNodes()

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.

Since: Coin 2.0

◆ getTypeId()

SoType SoMFNode::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoField. This is used for runtime type checking and "downward" casting.

Implements SoField.

◆ getValues()

const SoNode ** SoMFNode::getValues ( const int start ) const

inline

Returns a pointer to the values array.

◆ initClass()

void SoMFNode::initClass ( void )

static

Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.

◆ insertNode()

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

◆ insertSpace()

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.

◆ isSame()

SbBool SoMFNode::isSame ( const SoField & f ) const

virtual

Check for equal type and value(s).

Implements SoField.

◆ referencesCopy()

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 as well.

Reimplemented from SoField.

◆ removeAllNodes()

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

◆ removeNode() [1/2]

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

◆ removeNode() [2/2]

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

◆ replaceNode() [1/2]

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

◆ replaceNode() [2/2]

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
