DESCRIPTION

       This  field  maintains  a set of pointers to SoNode instances, correctly maintaining their
       reference counts.

       SoMFNodes are written to file as one or more nodes. When more than one value  is  present,
       all of the values are enclosed in square brackets and separated by commas; for example:

          [ Cube { }, Sphere { radius 2.0 }, USE myTranslation ]

METHODS

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

     SoNode *            operator [](int i) const
          Returns  the  i'th value of the field. Indexing past the end of the field (passing in i
          greater than getNum()) will return garbage.

     const SoNode * *    getValues(int start) const
          Returns a pointer into the array of values in the field, starting at index  start.  The
          values  are  read-only;  see  the  startEditing()/finishEditing()  methods for a way of
          modifying values in place.

     int                 find(SoNode * targetValue, SbBool addIfNotFound = FALSE)
          Finds the given value in the array and returns the index of that value in the array. If
          the  value  is  not found, -1 is returned. If addIfNotFound is set, then targetValue is
          added to the end of the array (but -1 is still returned).

     void                setValues(int start, int num, const SoNode * *newValues)
          Sets num values starting at index start to the values in newValues. The array  will  be
          automatically be made larger to accomodate the new values, if necessary.

     void                set1Value(int index, SoNode * newValue)
          Sets  the  index'th  value  in  the  array to newValue. The array will be automatically
          expanded, if necessary.

     SoNode *            operator =(SoNode * newValue)
     void                setValue(SoNode * newValue)
          Sets the first value in the array to newValue, and deletes the  second  and  subsequent
          values.

     int                 operator ==(const SoMFNode &f) const
     int                 operator !=(const SoMFNode &f) const
          Returns TRUE if all of the values of this field equal (do not equal) those of the given
          field. If the fields are different types FALSE will always be  returned  (even  if  one
          field is an SoMFFloat with one value of 1.0 and the other is an SoMFInt with a value of
          1, for example).

     SoNode * *          startEditing()
     void                finishEditing()
          startEditing() returns a  pointer  to  the  internally-maintained  array  that  can  be
          modified.  The  values  in  the  array  may  be  changed, but values cannot be added or
          removed. It is illegal to call any other editing  methods  between  startEditing()  and
          finishEditing() (e.g. set1Value(), setValue(), etc).

          Fields,  engines  or  sensors connected to this field and sensors are not notified that
          this field has changed until finishEditing() is called. Calling finishEditing()  always
          sets  the  isDefault()  flag  to  FALSE  and informs engines and sensors that the field
          changed, even if none of the values actually were changed.

                                                                                  SoMFNode(3IV)()
