Как прочитать весь список Published методов?

procedure EnumMethods( aClass: TClass; lines: TStrings );

  type
    TMethodtableEntry = packed Record
      len: Word;
      adr: Pointer;
      name: ShortString;
  end;
  {Note: name occupies only the size required, so it is not a true shortstring! The actual
  entry size is variable, so the method table is not an array of TMethodTableEntry!}

var
  pp: ^Pointer;
  pMethodTable: Pointer;
  pMethodEntry: ^TMethodTableEntry;
  i, numEntries: Word;
begin
  if aClass = nil then
    Exit;
  pp := Pointer(Integer( aClass ) + vmtMethodtable);
  pMethodTable := pp^;
  lines.Add(format('Class %s: method table at %p', [aClass.Classname, pMethodTable ] ));
  if pMethodtable <> nil then
  begin
    {first word of the method table contains the number of entries}
    numEntries := PWord( pMethodTable )^;
    lines.Add(format('  %d published methods', [numEntries] ));
    {make pointer to first method entry, it starts at the second word of the table}
    pMethodEntry := Pointer(Integer( pMethodTable ) + 2);
    for i := 1 to numEntries do
    begin
      with pMethodEntry^ do
        lines.Add(format( '  %d: len: %d, adr: %p, name: %s', [i, len, adr, name] ));
      {make pointer to next method entry}
      pMethodEntry := Pointer(Integer( pMethodEntry ) + pMethodEntry^.len);
    end;
  end;
    EnumMethods( aClass.ClassParent, lines );
end;
