Method End

cpp/src/arrow/util/iterator.h:51–51

\brief a reserved value which indicates the end of iteration. By default this is NULLPTR since most iterators yield pointer types. Specialize IterationTraits if different end semantics are required. Note: This should not be used to determine if a given value is a terminal value. Use IsIterationEnd (which uses IsEnd) instead. This is only for returning terminal values.

  /// terminal value.  Use IsIterationEnd (which uses IsEnd) instead.  This
  /// is only for returning terminal values.
  static T End() { return T(NULLPTR); }

  /// \brief Checks to see if the value is a terminal value.
  /// A method is used here since T is not necessarily comparable in many
