Expression

Description

g.elements_type

traits::is_nary_generator<G>::type

Metafunction that evaluates to mpl::true_ if a certain type, G is a NaryGenerator, mpl::false_ otherwise (See MPL Boolean Constant).

Invariants

For each element, E, in any NaryGenerator, G, the following invariant always holds:
