Detailed Description

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

Class NodeOverlap<DIM> represents the intersection between two node centered geometry boxes. It is a subclass of hier::BoxOverlap<DIM> and records the portions of index space that needs to be copied between two objects with node centered geometry.

Constructor & Destructor Documentation

template<int DIM> SAMRAI::pdat::NodeOverlap< DIM >::NodeOverlap (  const hier::BoxList< DIM > &  boxes, const hier::IntVector< DIM > &  src_offset )

The constructor takes the list of boxes and the source offset between the source and destination index spaces. This information is used later in the generation of communication schedules.

template<int DIM> SAMRAI::pdat::NodeOverlap< DIM >::~NodeOverlap (   )  [virtual]

The virtual destructor does nothing interesting except deallocate box data.

Member Function Documentation

template<int DIM> bool SAMRAI::pdat::NodeOverlap< DIM >::isOverlapEmpty (   )  const [virtual]

Return whether there is an empty intersection between the two node centered boxes. This method over-rides the virtual function in the hier::BoxOverlap<DIM> base class. Implements SAMRAI::hier::BoxOverlap< DIM >.

template<int DIM> const hier::BoxList< DIM > & SAMRAI::pdat::NodeOverlap< DIM >::getDestinationBoxList (   )  const [inline, virtual]

Return the list of boxes (in node centered index space) that constitute the intersection. The boxes are given in the destination coordinate space and must be shifted by -(getSourceOffset()) to lie in the source index space.

template<int DIM> const hier::IntVector< DIM > & SAMRAI::pdat::NodeOverlap< DIM >::getSourceOffset (   )  const [inline, virtual]

Return the offset between the destination and source index spaces. The destination index space is the source index spaced shifted by this amount. Implements SAMRAI::hier::BoxOverlap< DIM >.
