Detailed Description

template<int DIM, class TYPE>
class SAMRAI::pdat::NodeData< DIM, TYPE >

Class NodeData<DIM> manages data defined on nodes of cells in patches. It is a templated node-centered patch data structure derived from hier::PatchData<DIM>. Given a box, a node data object represents node-centered data of some template TYPE with a specified depth (that is, number of components for each spatial location). See the node geometry class for more information about the translation between the AMR index space and node-centered data.

A node data array is stored in (i,...,k,d) order, where i,...,k indicates spatial indices and the d indicates the component depth at that locaion. Memory allocation is in colum-major ordering (e.g., Fortran style) so that the leftmost index runs fastest in memory. For example, a three-dimensional node data object instantiated with a box [l0:u0,l1:u1,l2:u2] allocates a data array dimensioned as

     [ l0 : u0+1 ,
       l1 : u1+1,
       l2 : u2+1 , d ]

 * 
One- and two-dimensional node data arrays are managed similarly.

The data type TYPE must define a default constructor (that takes no arguments) and also the assignment operator.

Member Typedef Documentation

template<int DIM, class TYPE>
typedef NodeIterator<DIM> SAMRAI::pdat::NodeData< DIM, TYPE >::Iterator
 

The node iterator iterates over the elements of a node centered box geometry. This typedef is a convenient link to the NodeIterator<DIM> class.


Constructor & Destructor Documentation

template<int DIM, class TYPE>
SAMRAI::pdat::NodeData< DIM, TYPE >::NodeData const hier::Box< DIM > &  box,
const int  depth,
const hier::IntVector< DIM > &  ghosts,
tbox::Pointer< tbox::Arena pool = tbox::Pointertbox::Arena >((0))
 

The constructor for a node data object. The box describes the interior of the index space and the ghosts vector describes the ghost cells in each coordinate direction. The depth gives the number of components for each spatial location in the array. If the memory arena is not given, then the standard arena is used.

template<int DIM, class TYPE>
SAMRAI::pdat::NodeData< DIM, TYPE >::~NodeData  )  [virtual]
 

The virtual destructor for a node data object.


Member Function Documentation

template<int DIM, class TYPE>
void SAMRAI::pdat::NodeData< DIM, TYPE >::copy const hier::PatchData< DIM > &  src  )  [virtual]
 

A fast copy between the source and destination. Data is copied from the source into the destination where there is overlap in the underlying index space. The copy is performed on the interior plus the ghost cell width (for both the source and destination). If copy() does not understand the source object type, then copy2() is called.

template<int DIM, class TYPE>
void SAMRAI::pdat::NodeData< DIM, TYPE >::copy2 hier::PatchData< DIM > &  dst  )  const [virtual]
 

A fast copy between the source and destination. Member function copy2() is similar to copy() except that the location of source and destination are reversed and copy2() throws an exception (aka dumps core) if it does not understand the type of the argument.

template<int DIM, class TYPE>
void SAMRAI::pdat::NodeData< DIM, TYPE >::copy const hier::PatchData< DIM > &  src,
const hier::BoxOverlap< DIM > &  overlap
[virtual]
 

Copy data from the source into the destination using the designated overlap descriptor. The overlap description will have been computed using the appropriate box geometry objects. If copy() does not understand the source object type, then copy2() is called.

template<int DIM, class TYPE>
void SAMRAI::pdat::NodeData< DIM, TYPE >::copy2 hier::PatchData< DIM > &  dst,
const hier::BoxOverlap< DIM > &  overlap
const [virtual]
 

Copy data from the source into the destination using the designated overlap descriptor. Member function copy2() is similar to the copy() member function except that the location of source and destination are reversed and copy2() throws an exception (aka dumps core) if it does not understand the type of the argument.

template<int DIM, class TYPE>
void SAMRAI::pdat::NodeData< DIM, TYPE >::copyDepth int  dst_depth,
const NodeData< DIM, TYPE > &  src,
int  src_depth
 

Fast copy between the source and destination at the specified depths.

Data is copied from the source into the destination where there is overlap in the underlying index space. The copy is performed on the interior plus the ghost cell width (for both the source and destination).
