RTTI and Portability in C++
- by Joshua
If a compiler doesn't "support" RTTI, does that mean that the compiler can not handle class hierarchies that have virtual functions in them? Or have I been misunderstanding the literature about how RTTI isn't portable, and the issues lie elsewhere?Read the article

Rtti accessing fields and properties in complex data structures
- by Coco
As already discussed in Rtti data manipulation and consistency in Delphi 2010 a consistency between the original data and rtti values can be reached by accessing members by using a pair of TRttiField and an instance pointer. This would be very easy in case of a simple class with only basic member types (like e.g. integers or strings). But what if…Read the article

Delphi RTTI unable to find interface

I'm trying to fetch an interface using D2010 RTTI. program rtti_sb_1; {$APPTYPE CONSOLE} {$M+} uses SysUtils, Rtti, mynamespace in 'mynamespace.pas'; var ctx: TRttiContext; RType: TRttiType; MyClass: TMyIntfClass; begin ctx := TRttiContext.Create; MyClass := TMyIntfClass.Create; // This prints a list of all known…Read the article

Hi, If I have a superclass, say Animal, and two subclasses: Zebra and Giraffe, If I decide to define a Vector of Animals: Vector <Animal> animals = new Vector(); and I want to say: You can add Giraffes, but you must own at least one Zebra first. What is the best way to do this without using RTTI? (instanceof)Read the article

Delphi: RTTI and TObjectList<TObject>
- by conciliator
Based on one answer to an earlier post, I'm investigating the possibility of the following design TChildClass = class(TObject) private FField1: string; FField2: string; end; TMyClass = class(TObject) private FField1: TChildClass; FField2: TObjectList<TChildClass>; end; Now, in the real world, TMyClass will have 10…Read the article

Rtti data manipulation and consistency in Delphi 2010
- by Coco
Has anyone an idea, how I can make TValue using a reference to the original data? In my serialization project, I use (as suggested in XML-Serialization) a generic serializer which stores TValues in an internal tree-structure (similar to the MemberMap in the example). This member-tree should also be used to create a dynamic setup form…Read the article

Mixing libraries with and without RTTI with GCC on Mac OS X?

I've been banging my head on an issue and before I continue injuring myself some more, I'd like to confirm: Is it possible to have a GCC project that uses libraries that are compiled with and without RTTI? So, for example, I have project A (compiled without RTTI) that uses library B (compiled with RTTI) and library C (compiled…Read the article

Rtti for Variant Records

I try to write a kind of object/record serializer with Delphi 2010 and wonder if there is a way to detect, if a record is a variant record. E.g. the TRect record as defined in Types.pas: TRect = record case Integer of 0: (Left, Top, Right, Bottom: Longint); 1: (TopLeft, BottomRight: TPoint); end; As my serializer should…Read the article

Can I get a PTypeInfo from a string?
- by Mason Wheeler
This is probably going to be a "no", but is there any way I can use Delphi's RTTI, either old-school or the 2010 extended RTTI, to pass in a string containing the name of a type, specifically the name of an enumerated type, and have it give me the PTypeInfo for that type? I've looked through RTTI.pas and…Read the article

Delphi interface cast using TValue

Delphi 2010: whatever happened to TRTTIConstructor?

In an adjacent bullet point, on finds…Read the article

Delphi TRttiType.GetMethods return zero TRttiMethod instances

One logical next step would be to iterate…Read the article
