Hi, I'm pleased to finally announce the additional record operators: Initialize, Finalize. Download (r33200): http://svn.freepascal.org/svn/fpc/branches/maciej/smart_pointers "Record management operators aka record constructor/destructor" They working like low level auto-executed constructor/destructor for records. ===== motivation ===== It can be used for: -nullable types -very fast RTTI.TValue implementation -as replacement for manually called Init/Finit record methods for example like in mORMot for many types. -auto init/finit for fields of pointer/object type Additionally, it is base for my further work: -smart pointers -ARC objects -Oxygene mode -Delphi NextGen mode ===== example begin ===== {$MODE DELPHI} uses SysUtils; type TFoo = record private class operator Initialize(var aFoo: TFoo); class operator Finalize(var aFoo: TFoo); public F: Integer; S: string; P: Pointer; C: TObject end; class operator TFoo.Initialize(var aFoo: TFoo); begin F := 10; S := 'FPC rulezzz'; P := nil; C := nil; end;
What is the need for the (var aFoo: TFoo); ? Michael. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
