mrpt::aligned_allocator_cpp11< T, AligmentBytes > Class Template Reference

Detailed Description

template<class T, size_t AligmentBytes = MRPT_MAX_ALIGN_BYTES>
class mrpt::aligned_allocator_cpp11< T, AligmentBytes >

Aligned allocator that is compatible with C++11.

Default alignment can be 16 (default), 32 (if AVX is defined) or 64 (if AVX2 is defined). See: https://bitbucket.org/eigen/eigen/commits/f5b7700

This was used (before May-2019) to provide custom STL aligned containers, but the new(n,m) addition to C++17 rendered this needless (at last!) See: http://eigen.tuxfamily.org/bz/show_bug.cgi?id=1409

Anyway, this allocator class is left here just in case it is needed for something else.
