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

◆ getTypeId()

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.

◆ 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.

◆ isSame()

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

Check for equal type and value(s).

Implements SoField.

◆ getValues()

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

Returns a pointer to the values array.

◆ 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.

◆ 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 aswell.

Reimplemented from SoField.

◆ 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

◆ 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

◆ 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

◆ 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

◆ 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

◆ 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

◆ 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

◆ 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

◆ 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.

◆ 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.
