* \brief The macro defines an explicit operator of conversion to \c bool
|
|

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