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)()
