Detailed Description

template<typename T, size_t Alignment = CACHE_LINE_SIZE>
struct AlignedAllocator< T, Alignment >

A custom allocator to get aligned memory.

This allocator is intended to be used by std::vector

Template Parameters

T	The type of the elements this class should allocate memory for
alignment	The alignment restriction. Must be a power of 2, should not be 8.
