DESCRIPTION

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

       SoMFPaths are written to file as one or more paths (see  the  SoPath  manual  page  for  a
       description  of  the  file format for a path). When more than one value is present, all of
       the values are enclosed in square brackets and separated by commas.

METHODS

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

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

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

     int                 operator ==(const SoMFPath &f) const
     int                 operator !=(const SoMFPath &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).

     SoPath * *          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.

                                                                                  SoMFPath(3IV)()
