  \class SoMFInt32 SoMFInt32.h Inventor/fields/SoMFInt32.h
  \brief The SoMFInt32 class is a container for 32-bit integer values.
  \ingroup fields

  This field is used where nodes, engines or other field containers
  needs to store a group of multiple 32-bit integer values.

  This field supports application data sharing through a
  setValuesPointer() method. See SoMField documentation for
  information on how to use this function.
