Detailed Description

template<int DIM>
class SAMRAI::math::HierarchyNodeDataOpsInteger< DIM >

Class HierarchyNodeDataOpsInteger<DIM> provides a collection of operations that manipulate integer node-centered patch data components over multiple levels in an AMR hierarchy. It is derived from the abstract base class HierarchyDataOpsInteger<DIM> which defines the interface to similar operations for node-centered, face-centered, node-centered patch data objects where the data is of type integer. The operations include basic arithmetic and some ordering operations. On each patch, the operations are performed by the PatchNodeDataOpsInteger<DIM> data member.

The patch hierarchy and set of levels within that hierarcy over which the operations will be performed are set in the constructor. However, note that the constructor accepts default arguments for the coarsest and finest level numbers. If the level numbers are not specified when calling the constructor the levels which exist in the hierarchy will be assumed in all operations. The hierarchy and levels may be changed at any time using the proper member functions.

Note that, when it makes sense, an operation accept a boolean argument which indicates whether the operation should be performed on all of the data or just those data elements corresponding to the patch interiors.
If no boolean argument is provided, the default behavior is to treat only the patch interiors. Also, a similar set of operations for real (double and float) and complex node-centered data is provided in the classes HierarchyNodeDataOpsReal<DIM> and HierarchyNodeDataOpsComplex<DIM>, respectively.

Constructor & Destructor Documentation

◆ HierarchyNodeDataOpsInteger() [1/2]

template<int DIM>

SAMRAI::math::HierarchyNodeDataOpsInteger< DIM >::HierarchyNodeDataOpsInteger	(	tbox::Pointer< hier::PatchHierarchy< DIM > >	hierarchy,
		const int	coarsest_level = `-1`,
		const int	finest_level = `-1`
	)

The constructor for the HierarchyNodeDataOpsInteger<DIM> class sets the default patch hierarchy and coarsest and finest patch levels in that hierarchy over which operations will be performed. The hierarchy and operations may be reset using the member fuctions setPatchHierarchy() and resetLevels() below. If no level number arguments are given here, the levels over which the operations will be performed are those already existing in the hierarchy. If the hierarchy level configuration changes, the operations must be explicitly reset by calling the resetLevels() function.

◆ ~HierarchyNodeDataOpsInteger()

template<int DIM>

virtual SAMRAI::math::HierarchyNodeDataOpsInteger< DIM >::~HierarchyNodeDataOpsInteger ( )

Virtual destructor for the HierarchyNodeDataOpsInteger<DIM> class.

virtual

Reset patch hierarchy over which operations occur.

Implements SAMRAI::math::HierarchyDataOpsInteger< DIM >.

◆ resetLevels()

template<int DIM>

void SAMRAI::math::HierarchyNodeDataOpsInteger< DIM >::resetLevels	(	const int	coarsest_level,
		const int	finest_level
	)

virtual

Reset range of patch levels over which operations occur. Levels must exist in hierarchy or an assertion will result.

Implements SAMRAI::math::HierarchyDataOpsInteger< DIM >.

◆ getPatchHierarchy()

template<int DIM>

Return the total number of data values for the component on the set of hierarchy levels. If the boolean argument is true, the number of elements will be summed over patch interiors in a unique way which avoids multiple counting of redundant values (recall the definition of node points on a patch interior). If the boolean argument is false, all elements will be counted (including ghost values) over all patches.

d_nonoverlapping_side_boxes is extremely expensive to compute, and for whatever reason SAMRAI calls resetLevels() in most linear algebra functions: this results in, for problems with lots of patches, the majority of runtime being spent recomputing overlap repeatedly in solvers when we never actually need the information.
