Detailed Description

template<>
struct RefinementPossibilities< 2 >

A class that provides possible choices for isotropic and anisotropic refinement flags in the current space dimension.

This specialization is used for dim=2, where it offers refinement in x- and y-direction separately, as well as isotropic refinement in both directions at the same time.

Possibilities

enum RefinementPossibilities< 2 >::Possibilities

Possible values for refinement cases in the current dimension.

Note the construction of the values: the lowest bit describes a cut of the x-axis, the second to lowest bit corresponds to a cut of the y-axis and the third to lowest bit corresponds to a cut of the z-axis. Thus, the following relations hold (among others):

cut_xy  == cut_x  | cut_y
cut_xyz == cut_xy | cut_xz
cut_x   == cut_xy & cut_xz

Only those cuts that are reasonable in a given space dimension are offered, of course.

In addition, the tag isotropic_refinement denotes isotropic refinement in the space dimension selected by the template argument of this class.
