Class HDF5MDDataBlock<T extends ch.systemsx.cisd.base.mdarray.MDAbstractArray<?>>

java.lang.Object

ch.systemsx.cisd.hdf5.HDF5MDDataBlock<T>

public class HDF5MDDataBlock<T extends ch.systemsx.cisd.base.mdarray.MDAbstractArray<?>>
extends java.lang.Object

A class that is used for iterating over a data set block by block, using natural data blocks. The Natural block for chunked data sets is a chunk, for non-chunked data sets it is the complete array.

The pattern for using this class is:

 for (HDF5DataBlock<MDIntArray> block : reader.getIntMDNaturalBlocks(dsNameMD))
 {
     MDIntArray naturalBlock = block.getData();
     ... work on naturalBlock, use block.getIndex() or block.getOffset() where needed ...
 }
 

The iteration in the multi-dimensional case will be in C-order, that is last-index is iterated over first.

Note: If the size of the data set is not an integer number of blocks, then the last block will be smaller than the natural block size.

Method Summary

Modifier and Type	Method and Description
T	getData() Returns the data block itself.
long[]	getIndex() Returns the iteration index of this block, starting with { 0, ..., 0 }.
long[]	getOffset() Returns the offset in the data set for the current iteration in each dimension.
