35   \brief The SoMFVec2b class is a container for SbVec2b vectors.
36 
37   \ingroup fields
38 
39   This field is used where nodes, engines or other field containers
40   needs to store an array of vectors with two elements.
41 
42   This field supports application data sharing through a
43   setValuesPointer() method. See SoMField documentation for
44   information on how to use this function.
