DESCRIPTION

       A multiple-value field that contains any number of floating point values.

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

          [ 1.0, 2.3, 5, 6.2e4, -100, ]

     The last comma is optional.

METHODS

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

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

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

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

     float *             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.

                                                                                                SoMFFloat(3IV)()
