Help with serialization a record with set of enumerated

Hi,
I'm developing with Delphi 7 and I don't known how define the constant for this record. Can you help me?

type
  TPosFlag = (pfInService, pfSupervisorHelp, pfReadyForCalls, pfMakingCall,
    pfMakingCall2, pfReadyForChats, pfACDCall, pfACDChat, pfEnteringDigits);

  TPosData = packed record
    PosNumber: Word;                 
    UserId: Word;                    
    PosFlags: set of TPosFlag;
  end;

const
  __TPosData = 'PosNumber Word UserId Word PosFlags set of TPosFlag';

Thanks in advance.

Re: Help with serialization a record with set of enumerated

What do you want?

- Declare a constant for this record :

  TPosData = packed record
    PosNumber: Word;                 
    UserId: Word;                    
    PosFlags: set of TPosFlag;
  end;

const
  POSTDATA : TPosData = (PosNumber : 10; UserID : 11; PosFlags : [pfInService]);

  __TPosData).Options := [soReadIgnoreUnknownFields,soWriteHumanReadable];

Re: Help with serialization a record with set of enumerated

Define a specific type like

TPosFlags = set of TPosFlag;

Then register this simple type, and the __TPostData text, using "PosFlags: TPosFlags".

Re: Help with serialization a record with set of enumerated

Thanks Ab.
With this code fire the error: TJSONCustomParsers.Search(kind=6) not DynArray or Record.

type
  TPosFlags = set of TPosFlag;
const
  __TPosFlags = '(pfInService, pfSupervisorHelp, pfReadyForCalls, pfMakingCall, '+
                'pfMakingCall2, pfReadyForChats, pfACDCall, pfACDChat, pfEnteringDigits)';

type
  TPosData = packed record
    PosNumber: Word;
    UserId: Word;
    PosFlags: TPosFlags;
  end;
  TACDPositions = array of TPosData;
const
  __TPosData = 'PosNumber Word UserId Word PosFlags TPosFlag'
               

    TTextWriter.RegisterCustomJSONSerializerFromText(TypeInfo(TPosFlags),
 __TPosFlags).Options := [soReadIgnoreUnknownFields,soWriteHumanReadable];

Re: Help with serialization a record with set of enumerated

Use this method:

TTextWriter.RegisterCustomJSONSerializerFromTextSimpleType(TypeInfo(TPosFlags));
