Transform the boost::fusion::vector into memory specification (memory_traits) More...

Detailed Description

template<typename T>
struct memory_traits_inte< T >

Transform the boost::fusion::vector into memory specification (memory_traits)

Transform the boost::fusion::vector into memory_traits. In this implementation we interleave each property of the base type with memory_c

We basically create a buffer for each property

See also: see inter_mem_c for detail

Parameters

T	base type (T::type must define a boost::fusion::vector )

Definition at line 83 of file memory_conf.hpp.

#include <memory_conf.hpp>

Public Types
typedef inter_memc< typenameT::type >::type	type
	for each element in the vector interleave memory_c

typedef int	yes_is_inte
	indicate that it change the memory layout from the original

typedef boost::mpl::int_< SOA_layout_IA >	type_value
