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;
