This header defines a compatibility macro that implements an unspecified bool operator idiom, which is superseded with explicit conversion operators in C++11.

Definition in file explicit_operator_bool.hpp.

Macro Definition Documentation

#define BOOST_CONSTEXPR_EXPLICIT_OPERATOR_BOOL

(

)

Value:

BOOST_FORCEINLINE BOOST_CONSTEXPR explicit operator bool () const BOOST_NOEXCEPT\
    {\
        return !this->operator! ();\
    }

The macro defines a constexpr explicit operator of conversion to bool.

The macro should be used inside the definition of a class that has to support the conversion. The class should also implement operator!, in terms of which the conversion operator will be implemented.

BOOST_FORCEINLINE explicit operator bool () const\

The macro defines an explicit operator of conversion to bool.

The macro should be used inside the definition of a class that has to support the conversion. The class should also implement operator!, in terms of which the conversion operator will be implemented.

#define BOOST_EXPLICIT_OPERATOR_BOOL_NOEXCEPT

(

)

Value:

BOOST_FORCEINLINE explicit operator bool () const BOOST_NOEXCEPT\
    {\
        return !this->operator! ();\
    }

The macro defines a noexcept explicit operator of conversion to bool.

The macro should be used inside the definition of a class that has to support the conversion. The class should also implement operator!, in terms of which the conversion operator will be implemented.
