{ Run-Time type information routines }

{ The RTTI is implemented through a series of constants : }

Const 
       tkUnknown       = 0;
       tkInteger       = 1;
       tkChar          = 2;
       tkEnumeration   = 3;
       tkFloat         = 4;
       tkSet           = 5;
       tkMethod        = 6;
       tkSString       = 7;
       tkString        = tkSString;
       tkLString       = 8;
       tkAString       = 9;
       tkWString       = 10;
       tkVariant       = 11;

       tkBool          = 18;
 
{ A record is designed as follows : 
    1    : tkrecord
    2    : Length of name string (n);
    3    : name string;
    3+n  : record size;
    7+n  : number of elements (N)
    11+n : N times : Pointer to type info
                     Offset in record
}

Type

TRecElem = Record
  Info : Pointer;
  Offset : Longint;
  end;

TRecElemArray = Array[1..Maxint] of TRecElem;

PRecRec = ^TRecRec;
TRecRec = record
  Size,Count : Longint;
