UpValues
  • UpValues[ f ] gives a list of transformation rules corresponding to all upvalues defined for the symbol f.
  • You can specify the upvalues for f by making an assignment of the form UpValues[ f ] = list.
  • The list returned by UpValues has elements of the form HoldPattern[ lhs ] :> rhs.
  • See the Mathematica book: Section 2.4.13.
  • See also: Set, DownValues, HoldAllComplete.
