Classes
class	variant< Types >
	Represents a concrete instance of a run-time specified type from a set of typesA concept is typically modeled by a collection of different types. They may be instantiations of a templated type with different template parameters or even completely unrelated types. More...

Functions
template<typename Types , typename UnaryOp >
BOOST_FORCEINLINE UnaryOp::result_type	apply_operation (variant< Types > &arg, UnaryOp op)
	Invokes a generic mutable operation (represented as a unary function object) on a variant.
template<typename Types , typename UnaryOp >
BOOST_FORCEINLINE UnaryOp::result_type	apply_operation (const variant< Types > &arg, UnaryOp op)
	Invokes a generic constant operation (represented as a unary function object) on a variant.
template<typename Types1 , typename Types2 , typename BinaryOp >
BOOST_FORCEINLINE BinaryOp::result_type	apply_operation (const variant< Types1 > &arg1, const variant< Types2 > &arg2, BinaryOp op)
	Invokes a generic constant operation (represented as a binary function object) on two variants.
