Slicer

public Slicer()

Method Details

visit

public static void visit(ISliceViewIterator iterator,
 SliceVisitor visitor)
                  throws Exception

Throws:

Exception

visitParallel

public static void visitParallel(ISliceViewIterator iterator,
 SliceVisitor visitor,
 int nProcessors)
                          throws Exception

Throws:

Exception

getFirstSlice

public static org.eclipse.january.dataset.IDataset getFirstSlice(org.eclipse.january.dataset.ILazyDataset lz,
 Map<Integer,String> sliceDimensions)

getSliceViewGenerator

public static ISliceViewIterator getSliceViewGenerator(org.eclipse.january.dataset.ILazyDataset lz,
 Map<Integer,String> sliceDimensions)

getSize

public static int getSize(org.eclipse.january.dataset.ILazyDataset lz,
 Map<Integer,String> sliceDimensions)

Parameters:

lz -

sliceDimensions -

Returns:

size of expected iteration, slightly faster than calling getSlices(...).size()

getDataDimensions

public static int[] getDataDimensions(int[] shape,
 Map<Integer,String> sliceDimensions)

getSliceArrayFromSliceDimensions

public static org.eclipse.january.dataset.Slice[] getSliceArrayFromSliceDimensions(Map<Integer,String> sliceDimensions,
 int[] shape)

getSliceNDFromSliceDimensions

public static org.eclipse.january.dataset.SliceND getSliceNDFromSliceDimensions(Map<Integer,String> sliceDimensions,
 int[] shape)
