Never mind that, I changed the code after I wrote the message.
Here's the code in hopefully better formatting.
template < size_t LhsIndex, size_t RhsIndex, int Sign >
struct signature
{
typedef mpl::size_t< LhsIndex > lhs_index;
typedef mpl::size_t< RhsIndex > rhs_index;
typedef mpl::int_< Sign > type;
};
template < class Signature, class LhsIndex, class RhsIndex >
struct predicate
{
typedef typename mpl::and_<
typename mpl::equal_to<
typename Signature::lhs_index, LhsIndex
>::type,
typename mpl::equal_to<
typename Signature::rhs_index, RhsIndex
>::type
>::type type;
BOOST_MPL_AUX_LAMBDA_SUPPORT( 3,
predicate, (Signature, LhsIndex, RhsIndex) )
};
// Test code:
typedef mpl::vector< signature< 1, 1, 1 >,
signature< 4, 4, 0 >,
signature< 5, 5, 0 >,
signature< 4, 5, 1 > > signatures;
typedef mpl::find_if<
signatures,
predicate<
mpl::_1,
mpl::size_t< 4 >,
mpl::size_t< 5 >
>
>::type iter_0;
