A RTTI question - it is possible to determine if a certain property is Read-Only, 
Write-Only or stored?

Answer:

The following code checks whether a property can be written to, read or whether it 
is stored.


1   function IsWriteProp(Info: PPropInfo): Boolean;
2   begin
3     Result := Assigned(Info) and (Info^.SetProc <> nil)
4   end;
5   
6   function IsReadProp: Boolean;
7   begin
8     Result := Assigned(Info) and (Info^.GetProc <> nil)
9   end;
10  
11  function IsStoredProp: Boolean;
12  begin
13    Result := Assigned(Info) and TYPINFO.IsStoredProp(FObj, Info)
14  end;
