Detailed Description

template<class T>
class Eigen::aligned_allocator< T >

STL compatible allocator to use with with 16 byte aligned types.

Example:

// Matrix4f requires 16 bytes alignment:
std::map< int, Matrix4f, std::less<int>, 
          aligned_allocator<std::pair<const int, Matrix4f> > > my_map_mat4;
// Vector3f does not require 16 bytes alignment, no need to use Eigen's allocator:
std::map< int, Vector3f > my_map_vec3;
