Delphi 2010 RTTI : Explore Enumerations

Considering such an enumeration :

type
  TTypeOfData = (
    [XmlName('ABC')] todABC,
    [XmlName('DEF')] todDEF,  
    [XmlName('GHI')] todGHI
  );

Where XmlName is a custom attribute used to define the serialization string for members of this enumeration.

How can I explore the attributes attached to each member of this enumeration ?

Solution

  • Attributes associated with elements in enumerations are not currently stored in Win32 RTTI data in the executable. RTTI is already responsible for a fair increase in the size of executables, so some lines had to be drawn somewhere. Attributes in Delphi Win32 are supported on types, on fields of records, and fields, methods, their parameters, and properties of classes.

    The attribute declarations don't cause errors because of backward compatibility with Delphi for .NET.
