DESCRIPTION
       A multiple-value	field that contains any	number of two-dimensional vec-
       tors.

       SoMFVec2fs are written to file as one or	more pairs of  floating	 point
       values  separated  by  whitespace. When more than one value is present,
       all of the values are enclosed in square	brackets and separated by com-
       mas; for	example:

	  [ 0 0, 1.2 3.4, 98.6 -4e1 ]

METHODS
     void		 setValues(int start, int num, const float xy[][2])
	  Sets	num values starting at index start to the given	floating point
	  values. There	must be	num*2 values in	the passed array.

     void		 set1Value(int index, float x, float y)
     void		 set1Value(int index, const float xy[2])
	  Set the index'th value to the	given floating point values.

     void		 setValue(float	x, float y)
     void		 setValue(const	float xy[2])
	  Sets the field to contain the	given value and	only the  given	 value
	  (if the array	had multiple values before, they are deleted).

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

     const SbVec2f &	 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 SbVec2f *	 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()/fin-
	  ishEditing() methods for a way of modifying values in	place.

     int		 find(const  SbVec2f  &	 targetValue, SbBool addIfNot-
			      Found = 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 SbVec2f *newVal-
			      ues)
	  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, const SbVec2f & newValue)
	  Sets the index'th value in the array to newValue. The	array will  be
	  automatically	expanded, if necessary.

     const SbVec2f &	 operator =(const SbVec2f & newValue)
     void		 setValue(const	SbVec2f	& newValue)
	  Sets	the first value	in the array to	newValue, and deletes the sec-
	  ond and subsequent values.

     int		 operator ==(const SoMFVec2f &f) const
     int		 operator !=(const SoMFVec2f &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 ex-
	  ample).

     SbVec2f *		 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.
