All,

I'm wondering about the alignment requirements for nesting classes that use fixed-size matrices. I read the excellent documentation describing the why of such classes, such as:

Code: Select all

class Foo
{
  double x;
  Eigen::Vector2d v;
public:
  EIGEN_MAKE_ALIGNED_OPERATOR_NEW
};

The question I have is whether that alignment is now propagated, such that it is safe to have classes such as:

Code: Select all

class Bar
{
  char x;
  Foo foo;
public:
};
class Baz
{
  char x;
  Foo foo;
  short y;
  Bar bar;
public:
};

Or, would Bar and Baz be required to have the EIGEN_MAKE_ALIGNED_OPERATOR_NEW macro in the public: section?

Thank you.
