Integrals

The integrals of the ASN1 specification are supported in the Boost ASN1 library through a templated class called integral_t. This template is specialized for the four ASN1 integral data types.

ASN1 Type	C++ Equiv
INTEGER	integer_t
ENUM	enum_t
REAL	real_t
BOOLEAN	boolean_t

The actual C++ integral (bool, int32_t, double) is encapsulated inside the integral_t object. This allows for programmer to simply create a Boost.ASN1 integral type and immediately start using it as a C++ integral.

integer_t asnInt(20);

int32_t nativeInt = asnInt;

real_t asnReal;

asnReal = asnInt;

The integral types support the fundamental operators required by C++ integral data types:


`operator`	`operator()`	`operator T()`
`operator<`	`operator<=`	`operator>`
`operator>=`	`operator==`	`operator!=`
`operator+=`	`operator-=`	`operator*=`
`operator/=`	`operator%=`	`operator\|=`
`operator&=`	`operator^=`	`operator<<=`
`operator>>=`	`operator++`	`operator--`
