Detailed Description

Field containing a a node.

This field maintains a an SoNode instance , correctly maintaining its reference counts .

SoSFNodes are written to file as the node they are containing. For example:

   mySoSFNodeField Cube {}

is an SoSFNode field named 'mySoSFNodeField', referring to an SoCube node. If the node is used elsewhere, the regular DEF/USE instancing mechanism applies:

   anotherSoSFNodeField USE topSeparator

is an SoSFNode field that refers to a node named 'topSeparator' that was DEF'ed earlier in the scene.

Member Function Documentation

getClassTypeId()

static SoType SoSFNode::getClassTypeId ( )

static

Returns the type identifier for this class.

getTypeId()

virtual SoType SoSFNode::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Implements SoTypedObject.

getValue() [1/2]

SoNode * SoSFNode::getValue ( ) const

inline

Returns this field's value.

Definition at line 100 of file SoSFNode.h.

getValue() [2/2]

SoNode * SoSFNode::getValue

(

SbBool

getEffectiveNode = FALSE

)

Gets the value of this field.

The getEffectiveNode parameter is only used when the node in the field is a Proto. In this case, if the parameter is true then for convenience it returns the first child of the proto (the node the proto is pretending to be).

getValueSize()

virtual size_t SoSFNode::getValueSize ( ) const

inlinevirtual

Get size of the value.

Reimplemented from SoField.

Definition at line 100 of file SoSFNode.h.

operator!=()

int SoSFNode::operator!= ( const SoSFNode &  f ) const

inline

Returns FALSE if otherField is of the same type and has the same value as this field.

Definition at line 100 of file SoSFNode.h.

operator=() [1/2]

const SoSFNode & SoSFNode::operator=

(

const SoSFNode &

f

)

Copy from another field of same type.

operator=() [2/2]

SoNode * SoSFNode::operator= ( SoNode *  newValue )

inline

Sets this field to newValue.

Definition at line 100 of file SoSFNode.h.

operator==()

int SoSFNode::operator==

(

const SoSFNode &

f

)

const

Returns TRUE if otherField is of the same type and has the same value as this field.

setValue()

void SoSFNode::setValue

(

SoNode *
