Detailed Description

template<typename T>
class Opm::cuistl::detail::has_should_call_pre< T >

The has_should_call_pre class detects the presence of the method shouldCallPre.

Usage:

if constexpr (has_should_call_pre<decltype(preconditioner)>::value) {
    // We know that the function shouldCallPre is present:
    auto shouldCallPre = preconditioner.shouldCallPre();
}

Note

This is mainly done in the GPU preconditioner to avoid having to copy data in the pre step.
