DESCRIPTION

This field maintains a pointer to an SoNode instance, correctly maintaining its reference count.

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



mySoSFNodeField Cube {}

is an SoSFNode field named ’mySoSFNodeField’, pointing 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 points to a node named ’topSeparator’ that was DEF’ed earlier in the scene.

METHODS

    static SoType    
                    
static SoType        getClassTypeId()    
virtual void    
                    
virtual void         getTypeId() const
Returns the type for this class or a particular object of this class.

    SoNode *    
                    
SoNode *             getValue() const
Returns this field’s value.

    SoNode *    
                    
SoNode *             operator =(SoNode * newValue)    
void    
                    
void                 setValue(SoNode * newValue)
Sets this field to newValue.

    int    
                    
int                  operator ==(const SoSFNode &f) const    
int    
                    
int                  operator !=(const SoSFNode &f) const
Returns TRUE if f is of the same type and has the same value as this field.
