Detailed Description

template<int DIM>
class SAMRAI::pdat::OuternodeGeometry< DIM >

Class OuternodeGeometry<DIM> manages the mapping between the AMR index and the outernode geometry index space. It is a subclass of hier::BoxGeometry<DIM> and it computes intersections between outernode box geometries and node or outernode box geometries for communication operations.

See header file for OuternodeData<DIM> class for a more detailed description of the data layout.

inherited

Calculate the overlap between two box geometry objects given the source and destination (given by this) geometries, a source mask, the priority overwrite flag, and an offset between source and destination index spaces. The box overlap description returned by this function will be used in later copy and pack/unpack calls on the patch data object. The offset is from the source space into the destination index space. That is, if p is in the source index space, then p + sourceOffset is the corresponding point in the destination index space. The overwrite flag is used to represent priority between patches. If it is set, then the copy is allowed to modify the interior of the destination region. Note that the source and destination box geometries encode the geometry of the box that they represent; thus, it is possible to calculate intersections between different geometries. This will be necessary when copying data from flux sum counters into a face centered array in the AMR flux synchronization algorithm.

pure virtualinherited

Calculate the overlap between two box geometry objects given the source and destination geometries. This form calculateOverlap() is redefined by the subclasses of BoxGeometry<DIM> for the appropriate intersection algorithms. If calculateOverlap() cannot compute the intersection between the two given geometries and retry is true, then calculateOverlap() is called on the destination geometry object with retry set to false (to avoid infinite recursion). This protocol makes it possible to add new box geometry types and still calculate intersections with existing box geometry types.
