Detailed Description

template<typename T, size_t rank>
class schnek::SingleArrayLazyAllocation< T, rank >

Allocate a single array for multidimensional grids in C ordering.

Deallocation and allocation is performed only when required. When the memory need grows, the storage will allocate slightly more memory that needed. Shrinking of the allocated space happens lazily.

Use this, when a resize is expected regularly.

Template Parameters

T	The type of data stored in the grid
rank	The rank of the grid

Member Function Documentation

onUpdate()

template<typename T , size_t rank>

void schnek::SingleArrayLazyAllocation< T, rank >::onUpdate ( const UpdaterType &  updater )

protected

Add an updater to the data.

The updater is called when the data is resized.
