DESCRIPTION

49       This field maintains a pointer to an SoNode instance,  correctly  main‐
50       taining its reference count.
51
52       SoSFNodes  are  written  to  file as the node they are pointing to. For
53       example:
54
55          mySoSFNodeField Cube {}
56
57     is an SoSFNode field named 'mySoSFNodeField', pointing to an SoCube node.
58     If  the  node is used elsewhere, the regular DEF/USE instancing mechanism
59     applies:
60
61          anotherSoSFNodeField USE topSeparator
62
63     is an SoSFNode field that points to a node named 'topSeparator' that  was
64     DEF'ed earlier in the scene.
65

METHODS

67     static SoType       getClassTypeId()
68     virtual void        getTypeId() const
69          Returns  the  type  for  this  class  or a particular object of this
70          class.
71
72     SoNode *            getValue() const
73          Returns this field's value.
74
75     SoNode *            operator =(SoNode * newValue)
76     void                setValue(SoNode * newValue)
77          Sets this field to newValue.
78
79     int                 operator ==(const SoSFNode &f) const
80     int                 operator !=(const SoSFNode &f) const
81          Returns TRUE if f is of the same type and has the same value as this
82          field.
