Set is a template for emulating the intrinsic set types found in Object Pascal.

Header

sysset.h

Description

The Set<type, minval, maxval> is a C++ class template that implements the Delphi intrinsic type set.

Syntax

template<class T, unsigned char minEl, unsigned char maxEl>

class __declspec(delphireturn) Set;

You must specify three template parameters:

Parameter    Usage

type    the type of the elements (usually int, char, or an enum type)
minval    the minimum value the set can hold (this value cannot be less than 0)
maxval    the maximum value the set can hold (this value cannot be greater than 255)

Each instantiation of a Set creates an object based on all three parameters. Therefore, the following are two distinct types because they have different minimum and maximum values:

Set <char, 'A', 'C'> s1;

Set <char, 'X', 'Z'> s2;

if (s1 == s2)   // ERROR; illegal struct.

To create multiple instances of a Set type, use a typedef expression.

typedef Set <char, 'A','Z'> UPPERCASESet;

The declaration of a Set variable does not initialize the variable. You can declare the set types and initialize them by using the << operator, as shown in this example:

UPPERCASESet s1;

s1 << 'A' << 'B' << 'C';   // Initialize
UPPERCASESet s2;
s2 << 'X' << 'Y' << 'Z';   // Initialize

Note:    If you #include <iostream> or #define VCL_IOSTREAM before the include statement for sysset.h (which is typically included indirectly via vcl.h), you can use the streaming operators (<< and >>) with Set values as an argument:

template <class T, unsigned char minEl, unsigned char maxEl> ostream& operator <<(ostream& os, const Set<T, minEl, maxEl> & arg);
template <class T, unsigned char minEl, unsigned char maxEl> istream& operator >> (istream& is, Set<T, minEl, maxEl> & arg)
