value

template<typename T >

const int CP::detail::ContainerType< T >::value

static

Initial value:

= ( std::is_same< std::true_type, decltype( test_iparticle< T >( nullptr ) ) >::value ?
                                 1 : ( std::is_same< std::true_type, decltype( test_container< T >( nullptr ) ) >::value ?
                                       2 : 3 ) )

Value evaluating to:

• 1 for xAOD::IParticleContainer types;
• 2 for other DataVector types;
• 3 for non-vector types.
