template<unsigned int dim, typename T, typename S, typename layout_, template< typename > class layout_base>

void grid_base_impl< dim, T, S, layout_, layout_base >::setMemory ( S & m )

inline

Get the object that provide memory.

An external allocator is useful with allocator like PreAllocHeapMem to have contiguous in memory vectors. Or to force the system to retain memory

Template Parameters

S	memory type

Parameters

m	external memory allocator

Is external

Create and set the memory allocator

Allocate the memory and create the reppresentation
