This example shows how to get the RTTI available for records methods.

Code

program Program1;

{$APPTYPE CONSOLE}

uses
  SysUtils,
  Rtti;

type
  TKey = record
  private
    FData: array[0..15] of Byte;
  public
    function GetByte(Index: Integer): Byte;
    // ...
  end;

function TKey.GetByte(Index: Integer): Byte;
begin
  // ...
end;

var
  LContext: TRttiContext;
  LType: TRttiType;
  LRecord: TRttiRecordType;
  LMethod: TRttiMethod;

begin
  LContext := TRttiContext.Create;

  LType := LContext.GetType(TypeInfo(TKey));
  if LType.IsRecord then
  begin
    LRecord := LType.AsRecord;

    { List all TKey methods }
    for LMethod in LRecord.GetMethods do
    begin
      Writeln(LMethod.ToString);
    end;
  end;

  LContext.Free;

end.

Console Output

function GetByte(Index: Integer): Byte
