//! \ingroup OpenMaya MFn
//! \brief Function set for multiple arrays of attributes for dependency node data. 
/*!
  MFnArrayAttrsData allows the creation and manipulation of multiple
  arrays of attributes as a data object over a single connection for use
  as dependency graph data.

  If a user written dependency node either accepts or produces
  MFnArrayAttrsData, then this class is used to extract or create
  the data that comes from or goes to other dependency graph nodes.
  The MDataHandle::type method will return kDynArrayAttrsData when data
  of this type is present. To access it, the MDataHandle::data() method
  is used to get an MObject for the data and this should then be used
  to initialize an instance of MFnArrayAttrsData.

  NOTE: these data attributes are not storable.
