Detailed Description

template<typename T0_, BOOST_VARIANT_ENUM_SHIFTED_PARAMS(typename T)>
class misc::generic_variant< T0_, >

A wrapper over boost::variant supporting conversion operators.

Preconditions:

• Each type must be unique.
• No type may be const-qualified.

Proper declaration form: misc::generic_variant<types> (where types is a type-sequence) or misc::generic_variant<T0,T1,...,Tn> (where T0 is NOT a type-sequence)

template<typename T0_ , BOOST_VARIANT_ENUM_SHIFTED_PARAMS(typename T) >

misc::generic_variant< T0_, >::operator T0_ &

(

)

Convert this variant to a value of type U.

This conversion rely on boost::get. In particular, if the conversion fails, a boost::bad_get exception is thrown.
