The BOOST_PP_TUPLE_ENUM macro converts a tuple to its comma-separated elements. The comma-separated elements are in the form of variadic data.

Usage

BOOST_PP_TUPLE_ENUM(size,tuple)

or

BOOST_PP_TUPLE_ENUM(...) (v)

Arguments

size
The size of the tuple.  Valid tuple sizes range from 1 to BOOST_PP_LIMIT_TUPLE.
tuple
The tuple whose elements are to be converted.

Remarks


You can invoke the variadic version (v) as BOOST_PP_TUPLE_ENUM(tuple) or BOOST_PP_TUPLE_ENUM(size,tuple).
