Detailed Description

template<typename T, typename D>
class memory_c< multi_array< T >, D >

Specialization of memory_c for multi_array.

Specialization of memory_c for multi_array

It is mainly used by memory_conf to create the correct layout

Template Parameters

T	is suppose to be a boost::mpl::vector specifing at position 0 the type and at position 1 to N the dimensions size of the multi_array
D	object that allocate memory

template<typename T , typename D >

template<int S>

using memory_c< multi_array< T >, D >::int_ = boost::mpl::int_<S>

private

define T

define boost::mpl::int_ without boost::mpl

Definition at line 247 of file memory_c.hpp.

template<typename T , typename D >

typedef boost::multi_array<base,size_p::value> memory_c< multi_array< T >, D >::type

define the type of the multi_array vector minus one of the original size basically we remove the index 0 of the multi_array

Member Function Documentation

template<typename T , typename D >

bool memory_c< multi_array< T >, D >::allocate ( const size_t  sz )

inline

This function allocate memory and associate the representation to mem_r.

This function allocate memory and associate the representation of that chunk of memory to mem_r

We create a chunk of memory

buffer to store the dimensions of the full multi_array buffer

we generate the ordering buffer ord::data = {0,N-1 ...... 1 }

we create the representation for the memory buffer

Definition at line 324 of file memory_c.hpp.

template<typename T , typename D >

memory& memory_c< multi_array< T >, D >::getMemory ( )

inline

This function get the object that allocate memory.

Returns

memory object to allocate memory

Definition at line 313 of file memory_c.hpp.

template<typename T , typename D >

void memory_c< multi_array< T >, D >::setMemory ( memory &  mem )

inline

This function set the object that allocate memory.

Parameters

mem	the memory object
