Detailed Description

Class SideCellSynchCopyFillPattern is a concrete implementation of the abstract base class SAMRAI::xfer::VariableFillPattern. It is used to calculate overlaps according to a pattern which limits overlaps to the side-centered ghost region surrounding a patch appropriate for "synchronizing" side-centered values at patch boundaries.

overridevirtual

Calculate overlaps between the destination and source geometries according to the desired pattern. This will return the portion of the intersection of the geometries that lies in the ghost region of the specified width surrounding the patch, excluding all edges and corners. The patch is identified by the argument dst_patch_box.

Parameters

dst_geometry	geometry object for destination box
src_geometry	geometry object for source box
dst_patch_box	box for the destination patch
src_mask	the source mask, the box resulting from shifting the source box
overwrite_interior	controls whether or not to include the destination box interior in the overlap
src_offset	the offset between source and destination index space (src + src_offset = dst)
