Detailed Description

template<class T, int Alignment = -1>
class Dune::AlignedAllocator< T, Alignment >

Allocators which guarantee alignment of the memory.

Template Parameters

T	type of the object one wants to allocate
Alignment	explicitly specify the alignment, by default it is std::alignment_of<T>::value
