Detailed Description

LOCAL interface on cartesian dense data that presents a window. This allows for a self-similar interface to a smaller block within the window.

 Example:
 LocalArray Window *awin; // assumed 2D
 enum RawDataType::RawDataType dataType;
 int rank;
 int *lbc, *ubc, *stride, *ld;
 void * array;
 awin->getInfo(dataType, rank);
 awin->getData(lbc, ubc, stride, ld, array);
 for (int j = lbc[1]; j <= ubc[1] ; j += stride[1]) {
     for (int i = lbc[0]; i <= ubc[0] ; i += stride[0]) {
      x += array[(j*ld[0])+ i];
     }
 }

virtual const char* LocalArrayWindow::getName

(

)

[pure virtual]

Get the name of this object.

virtual void LocalArrayWindow::getInfo	(	enum RawDataType::RawDataType &	dataType,
		int &	rank
	)		[pure virtual]

Basic info lookup, in case we want a copy version of getData. LocalArray Window *awin; // assumed 2D enum RawDataType::RawDataType dataType; int rank; int *lbc, *ubc, *stride, *ld; void * array; awin->getInfo(dataType, rank); awin->getData(lbc, ubc, stride, ld, array); for (int j = lbc[1]; j <= ubc[1] ; j += stride[1]) { for (int i = lbc[0]; i <= ubc[0] ; i += stride[0]) { x += array[(j*ld[0])+ i]; } }

Parameters:

rank	1d,2d,3d array.

virtual void LocalArrayWindow::getData	(	const int &[]	lowerBoundsC,
		const int &[]	upperBoundsC,
		const int &[]	stride,
		const int &[]	leadingDimensions,
		const void *&	data
	)		[pure virtual]

Get the info needed for iteration. We may want locking(read/write),release. We assume Babel will solve the index from 1 problem in the FORTRAN binding.

Parameters:

lowerBoundsC	0-indexed array of lower bounds.
upperBoundsC	0-indexed array of upper bounds.
stride	step in each dimension.
leadingDimensions	size of actual array in each dimension.
array	the same pointer regardless of window lowerbounds.
