Question:
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.
function IsWriteProp(Info: PPropInfo) : Boolean;
begin
Result := Assigned(Info) and (Info^.SetProc<>nil)
end;
function IsReadProp : Boolean;
begin
Result := Assigned(Info) and (Info^.GetProc<>nil)
end;
function IsStoredProp : Boolean;
begin
Result := Assigned(Info) and TYPINFO.IsStoredProp(FObj, Info)
end;
