Sets

A Delphi set is simulated in the C++ VCL by the class Set:

template<class T, unsigned char minEl, unsigned char maxEl>
class __declspec(delphireturn) Set;

MySet: set of 'a'..'z';
->
System::Set < char, 97, 122 > MySet;

If there is no explicit type-declaration of a set, as e.g. in:

MySet := ['a','b','c'];

a helping macro is created:

#define test__0 (System::Set< char, 0, 255 >() 
   << char ( 97 ) << char ( 98 ) << char ( 99 ) )

MySet = test__0;
