Detailed Description

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

Class HierarchyNodeDataOpsComplex<DIM> provides a collection of operations that manipulate complex node-centered patch data components over multiple levels in an AMR hierarchy. It is derived from the abstract base class HierarchyDataOpsComplex<DIM> which defines the interface to similar operations for node-centered, face-centered, node-centered patch data objects where the data is complex. The operations include basic arithmetic and norms. On each patch, the operations are performed by the PatchNodeDataOpsComplex<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 integer node-centered data is provided in the classes HierarchyNodeDataOpsReal<DIM> and HierarchyNodeDataOpsInteger<DIM>, respectively.

Constructor & Destructor Documentation

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

The constructor for the HierarchyNodeDataOpsComplex<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.
